Deep Linkning in Roku

Deep Linking in Roku

Deep Linking is widely used for the purpose of launching the public channel, performing the universal search and for directly opening to a specific part of the video that is in a public channel. The Roku app developer needs to implement the deep linking in order to access a piece of video content directly rather than accessing it only from the home page. The latest Roku app development guidelines have stated that all the public channels will be essentially important to completely implement the deep link to pass the certification.

In this article, we have discussed the implementation process of deep linking in Roku by the Roku app developer.

What is Deep Linking in Roku?

Deep linking in Roku allows the users to get to their content quickly from the Roku UI via content discovery features of Roku such as Roku Search and Roku home screen banners. While deep linking in Roku, your channel is launched into content springboards or playback directly from the Roku UI. For instance, whenever you select a movie from Roku Search, immediately the playback starts without any navigation of the channels. This feature allows you to take the full advantages of Roku’s content discovery features for driving the users to your channel and increasing engagement.

What are the Deep Linking Parameters in a Roku Channel?

Deep link requests include two parameters: contentid and mediaType.

  • A contentId can be defined with some valid ASCII string that is less than 255 characters in length. The Roku channel must have behaviors like handling invalid deep links, the unauthenticated users and displaying paywall when responding to the deep link request. In order to enable this deep linking, every piece of content present in the channel is identified by means of a unique string identifier.
  • The next process step will be to associate a proper Roku defined mediaType with each contentId. The purpose of this mediaType is to convey to the Roku platform on handling the specific content. The content id must be an opaque string, a single string, URL encoded, as a command-line argument and be immutable. Once both the content id and media type are defined, they shouldn’t be changed until the Roku app is developed.

How to Implement Deep Linking in a Roku Channel?

The Roku app developer must follow the below series of steps to perform the deep linking process in the Roku Channel resulting in advanced Roku app development.

  • Step 1: Modifying the main.brs file of the channel.
  • Step 2: Testing the validity of args[contentid] and args[MediaType].
  • Step 3: Adding code to launch.
  • Step 4: For a series, implement bookmarking.
  • Step 5: Using roInputEvent.
  • Step 6: Testing with the help of Deep Linking in Roku Channel Tester application.

Now, as we have understood the basic steps required for deep linking in a Roku channel, let us understand them with some more clarity.

Step 1: Modifying the main.brs file of the channel

The Roku app developer has to first modify the Roku channel’s main.brs file in order to handle the deep linking. This can be done by either editing the Roku channel’s main() or the runuserinterface(). One more argument must be added to the function and can be named as args. The main() function must be modified so that the channel can accept the deep linking parameter easily.

This will be like, Function Main (args as Dynamic) as void.

The parameters of the function would be the contentId for defining a piece of content, the mediatype to identify the media type of the context and the third one is the correlator is the optional argument that is sent by ads during the launch of the channel.

Step 2: Testing the validity of args[contentid] and args[MediaType]

Adding the test code for args[contentid] and the args[MediaType]The code must be added in order to test the args[contentid] as well as the args[MediaType] are not the valid ones. In case these have values, then they are deep linked with So the testing condition will be like:

Function Main (mainArgs as Dynamic) as Void

If (mainArgs.ContentId <> invalid) and (mainArgs.MediaType <> invalid)

print “Channel is deep linked”

End If

End Function

Step 3: Adding code to launch

The next step for implementing the deep linking in the Roku channel is to add the code for launching the required scene whenever the contentId is valid. In case they are invalid, the Roku app developer has to ensure that the corresponding error message gets displayed.

Function Main (mainArgs as Dynamic) as Void

If (mainArgs.ContentId <> invalid) and (mainArgs.MediaType <> invalid)

If (mainArgs.mediaType = “movie” )

print “Play Movie “, mainArgs.ContentId

Else If (mainArgs.mediaType = “live” )

print “Play Live “, mainArgs.ContentId

End If

End If

End Function

Step 4: For a series, implement bookmarking

This should be followed by the implementation of bookmarking for the series. The decision must be taken as to which episode has to be played. Once decided, go to the specific episode part and begin the playback option. Precise knowledge on finding a suitable place for playback in the episode should be known.

Step 5: Using roInputEvent

When the channel is running, it is necessary to use the roInputEvent for the purpose of catching deep links thereby preventing the delays in the channel launching. Direct playback commands can be deep linked to channel content by the Roku developer.

Step 6: Testing with the help of Deep Linking in Roku Channel Tester application

The Roku developer must then test the process using the deep linking tester tool. One step is to try curl -d ” ” ‘http://ip-address:8060/launch/dev?contentID=123456&MediaType=live’ One can gain insights on testing the deep linking using the Roku deep linking tester tool.

Conclusion

We hope you will find this article helpful. After going through this article you will be easily able to implement deep linking in a Roku channel even if you are on a beginner level. You can also take help from several deep linking video lessons or by contacting 4 Way Technologies to get the best possible outcome as per your requirement.

How To Design and Develop Android TV App [ 2021 Tutorial ]

Over the last few years, the applications on television have taken the user experience to the next level as it offers a lot of comfort to the customers. Android, in specific, offers an exquisite user experience that is specifically optimized and structured for the application to run on large screen devices with high resolutions.

This blog walks you through the designing and developing process of the Android TV app.

Introduction

Android ensures that developing apps for the TV is very similar to the procedure for creating apps for phones or tablets.

One of the interesting highlights is to develop apps successfully on TV devices. The layouts must be designed in such a way that can be easily understood from nearly 10 feet away and offer a good degree of navigation.

So, let’s dive in!

Prerequisites for Android TV App Development

To get started with the Android TV application, the structure for the phones can be used. An important requirement is that the app developer must definitely meet some requirements to be considered as Android TV apps. The other important prerequisites will be to ensure that the SDK tools are updated to version 24.0 or higher, SDK with Android 5.0 with API 21 or higher is available. 

The following is the architecture of Android TV application architecture with its components:

Android TV Application Architecture

Finding the Specific Media Format Support

While developing the Android TV application, it is necessary to know in detail about the codecs, protocols, and formats that are completely supported by the Android TV. Any type of media codec can be used based on the requirements of the developer. It is generally highly advised to use the media encoding profiles which are classified as device-agnostic. 

Developers must also know about the DRM ( Digital rights management) before creating an application for the TV devices and the ExoPlayer library can also be used for implementing the high functionalities while creating the application. The following image has a common video format and codes.

Android TV App Development Tutorial

Setting Up the TV Project for Android

The prominent components that are used for the creation of the Android TV applications are the Activity for TV and the TV support libraries. While developing, the activity to run must be declared in the application manifest file. 

The libraries are optional while developing Android TV apps. A wide range of support libraries is present for the TV devices which definitely helps in scaling the appearance of the application to the next level in the form of widgets which eventually make up an intuitive user interface.

Declaration of the TV Activity

A launcher activity must be defined in the application manifest file. This is a must for any application that has to run on television devices. This can be done with the help of an intent filter CATEGORY_LEANBACK_LAUNCHER. 

The functionality of this filter is to ensure that your designed application is enabled for the TV devices. The intent is the one that decides the activity to launch when the user clicks on the application.

<application

android:banner=”@drawable/banner” >

<activity

android:name=”com.example.android.MainActivity”

android:label=”@string/app_name” >

<intent-filter>

<action android:name=”android.intent.action.MAIN”/>

<category android:name=”android.intent.category.LAUNCHER”/>

</intent-filter>

</activity>

<activity

android:name=”com.example.android.TvActivity

android:label=”@string/app_name”

android:theme=”@style/Theme.Leanback”>

<intent-filter>

<action android:name=”android.intent.action.MAIN”/>

<category android:name=”android.intent.category.LEANBACK_LAUNCHER”/>

</intent-filter>

</activity>

</application>

When an existing application is extended for use on the television, one should never use the same activity layout of the mobile version for the televisions. The user interface of the television app should be having a simpler interface for simpler and easy navigation. There are some intuitive general TV design principles for development.

Declaring the Lean Back Support And Use of Home Screen Banner

It is very important to declare that the application uses the lean-back user interface. If you intend to develop applications to run on both TV and mobile, you will have to set the required attribute value to false. If the value is set as true, the app will run on devices that only use the Leanback user interface. 

When an app has the Leanback launcher filter, the home screen banner becomes mandatory for localization purposes. The banner must be added to the app’s manifest file as it is the launch point that becomes visible to the users on the home screen in apps.

<manifest>

<uses-feature android:name=”android.software.leanback”

android:required=”false”/>

</manifest>

Home Screen Banner

<application

android:banner=”@drawable/banner” >

</application>

The banner must definitely be an xhdpi resource with a size of 320 x 180 px.  To include the banner in the manifest file, the attribute android: banner can be used within the <application> tag. The text needs to be included in the pic. Below is a sample of the home screen banner of Android TV.

Simple Home Screen Banner for Android TV

The television application’s manifest need not declare the android: hardware. touchscreen feature as the operations of the TV devices need not rely on the touch screen as a form of input.

No Touchscreen Declaration

<manifest>

<uses-feature android:name=”android.hardware.touchscreen”

android:required=”false”/>

</manifest>

No Changing of the Launcher Color

The interesting feature in the development of the Android TV application is the ability to customize the color of the application. This can be done by setting the android: color primary attribute of the television app. Additionally, the developer must also set two more transition overlap attribute values as true. The following is a snippet example from a theme XML format file.

<resources>

<style … >

<item name=”android:colorPrimary”>@color/primary</item>

<item name=”android:windowAllowReturnTransitionOverlap”>true</item>

<item name=”android:windowAllowEnterTransitionOverlap”>true</item>

</style>

</resources>

The TV Support Libraries

To design and develop the Android TV application in an interactive and intuitive manner, the TV support libraries are a must. These play a very vital role as they provide the APIs as well as the widgets for the TV devices. These libraries are generally found to be located in the path- <sdk>/extra/android/support/ directory.

Some of the common ones are the v17 Leanback library– this provides a wide range of UI widgets that are very much required for the TV applications that never need the media playback. The next important TV support library is the v8 recyclerview library that generates the classes to manage the display of the lists efficiently. The next one is the v7 card view library that offers the UI widgets for card views and description.

Running the TV Application

Once the Android TV app is developed, you will have to run the app on TV devices. The TV devices should be configured to the USB debugging mode or the user of virtual television devices is also encouraged. While running on the real device, the following steps will have to be followed:

  • With the help of the USB cable, connect your TV to the machine that has been used for the development Then switch on the TV, and choose the Settings option, You should then click on the device option and select about.
  • Once this is done, scroll down through the options and locate the build option. Click that option many times to enable the developer mode. Now choose settings, then preferences followed by the developer options.
  • The developer must then select debugging, then USB debugging to switch it ON.

Running the Developed Application on the Virtual Device

AVD Manager ( Android virtual device ) helps in running the application on the virtual device. The developer needs to start the AVD manager, choose the device definitions, then click on their preferred TV configurations and create the AVD.

Testing the Developed Android TV Application

In order to test the application on the TV device, you will have to choose the project and choose the run option. Then the deployment target must be chosen to test your application. This will help you identify the bugs, run the debugger and rectify the errors.

The developers are provided the opportunity to build the TV playback applications for entertainment purposes that can be done in the form of intuitive user interface tools and widgets. 

TV games can also be built as it is the best platform to play games with a large screen. The video can also be presented with a wide range of channels and programs. Thus the steps for building an intuitive, interactive android application for the TV devices with the TV support libraries along with the running and testing of the application are finished.

Conclusion

After going through this article, we hope you will be able to design and develop your own Android TV app even if you are starting your career in Android TV app development or you are a pro developer.

Introduction

Apple tv app development Apple provides two diverse approaches in designing applications for the APPLE TV. One way for developing apps is using the Television Markup Language (TVML) and the other way is a general iOS app which is a custom method. People who want more customized features in their application definitely opt for the latter method. These two approaches play a critical role in helping the designing and developing of applications for the APPLE TV.

How to Create a TVML Application?

While creating the first TVML application, the first step will be to completely set up the server and create the initial TVMLKit Javascript file. People deciding to follow this JavaScript centered approach can build their application with a series of JavaScript pages. You can know more about creating a simple application using the TVML approach. Below is the workflow of the TVML approach in designing and developing applications for the APPLE TV.

TVML Approch

This approach helps in the creation of the applications using TVMLKit Javascript files, the markup language (Apple TV Markup language) as well as the framework. The majority of the TVML applications are usually client-server applications. They should have extensive in-depth knowledge of javascript. While creating your TVML app, you need to follow the below steps:

1. Setting Up Your Server

One has to decide whether to host the content on their own server or through any hosting site. If you decide to proceed with the hosting site, then you have the liberty to leave all the responsibilities of setting up the server to them inclusive of fixation issues.

The developer needs to decide whether the content should be hosted on their own server or through the hosting site. You can opt for the hosting site as all the server outages are usually taken care of by them.

The only drawback would be that you will have to wait for a specific period for the hosting site to fix the problem. Setting up your own server will indeed provide a great level of control over how the content is being organized and you become filly responsibilities for the server functionalities and resolving its errors.

Irrespective of setting up the server on your own server or through the hosting site, you should necessarily know the path to the initial TVMLKit JS file. This is the place from where all the TVML page templates can be easily accessed. The below image shows how a TVML application can be created after the server is set up.

LG TV Application

2. Creating the XCode Application

The APPLE TV template applications should be designed using the Xcode. Such apps point towards the initial TVMLKit JS file. While creating some template app, you need to select the select tvOS option, then choose an application and then the TVML application. Once the name of the product is entered, the skeleton of the app gets created.

Two major static constants get created namely tvBaseURL and the tvBootURL. The former contains a URL pointing to the server, while the latter contains the exact location where the initial TVMLKit JS file is found. The standard web server is needed in order to host the assets from which you will be able to access the templates. The below image shows the different templates available for the project to be created in your Xcode application.

The Apple TV temple applications are designed and created in Xcode. These are generally simple applications that point to the initial TVMLKit JS file for the application. To create a new template application, you will need to select the tvOS -> Application -> TVML application.

3. Integrating the Components

Once the server is fully set up and the creation of the Xcode application is done, you should then create the initial TVMLKit JS File. The major purpose of this JS file is that it must definitely implement the App.onLaunch function. These functions must serve the purpose of parsing the TVML code into the Document Object Model (DOM tree), as well as push the DOM tree into the navigation stack.

Now, the JavaScript files can be created with the code in them. The next step is to change the already present tvBootURL constant to the AppDelegate.tvBaseuRL/(first JS file name). Care should be taken that the local server is run from the same directory where the initial TVMLKit JS file is also present. Creation of the dynamic pages can be known here.

The biggest advantage of using TVML is the presence of simple, compound elements as well as the templates. The limitations while using TVML is that it is suited only for the lightweight apps that are not suited for gaming apps.

What are Custom Apps and How They are Implemented?

These are usual iOS apps which are extended to adapt to the tvOS SDK. This approach requires an extensive usage of Swift or the Objective-C languages. Over the last few years, many people have begun to use this approach in designing and developing the applications for the APPLE TV.

The following are the steps for successful implementation of the application:

1. The Focus Engine

The focus, in general, refers to the onscreen effect as well as indirect user input from the input device. The developer must surely rely on a remote that incorporates the Focus Engine to focus on a particular item using the remote swiping gestures. It must be remembered that not all items are focusable and that users easily change the focus by choosing the direction on their remote.

Storyboards and elements must be designed ensuring that they are conducive to the single focus navigation. The other point to be noted is that only the user is capable of changing the focus completely, changing the focus and the focus gets completely managed by its environment.

2. Ensuring that the Already Existing iOS Elements Conform to the tvOS

It is a happy fact that many Apple frameworks like the UIKit support the focus engine thereby can be used for creating apps for the APPLE TV without additional code. The UITextField, the UISearchBar also has focus support thereby supporting the design of apps for the Apple TV.

With the help of the UIFocus Environment, the developer can easily dictate the steps on how each UI element reacts to the changes that happen around. This will provide access to all the focus environments, also the movement of the focus as well as its response.

3. Presence of Custom Support for the Focus Engine

The users will have to design the custom UI elements for focussing since these will lack the inherent focus support. Users can completely design their own UI elements, determine their own functionalities and also be able to gain access to the updates in the Focus Engine. In case for the user interface elements that lack inherent focus support, the developer will need to come up with an implementation of their own customer behavior for the purpose of focusing.

The biggest striking advantage of this approach is that one can design robust iOS apps with a high level of functionalities. If one had to design an app with only video or audio content with fewer functionalities, it would be wiser to opt for the TVLM approach.

The latest update from Apple is that a very new updated Apple TV iteration has been released. The biggest highlight of this release is that it has ensured the framework as a completely fully-fledged third-party developer’s platform. With the new introduction of the Siri-powered remote, users are now able to experience gesture navigation and other high functionalities that are developed by the coders by using either of the approaches.

Conclusion

We hope you will find this blog helpful. After going through this article, you will be easily able to understand the development and designing process of Apple TV applications. If you are a developer, this blog can also help you in building your own Apple TV app even if you are on a beginner level.

Introduction

As the need for Android devices is increasing at a fast pace, the demand for developing new Android apps is also increasing at a rapid rate. Android Studio is a free and easy-to-use Android applications development environment. If you are a beginner and have some good knowledge about Java programming language, it would be a great aspect for you as Java is the programming language, which is used mainly in Android app development.

This tutorial walks you through the basics of developing an Android app with the help of the Android Studio development environment.

So, let’s start!

What Are the Major Component Files During Mobile App Development?

On opening the Android Studio, you will find a series of options. The developer has to select the option ‘Start a new Android Studio Project’. You can also go to the file option and choose the new project option to open up a new project template. 

The application name, company domain, and project location can be changed based on convenience. The target Android devices can be then chosen with the values, an empty activity can be chosen to begin coding. The following is the screen sample for the various activities present in the Android Studio.

By selecting the app->Java->com.example.project name>Main Activity-

This would be the main entry point for the application to be created. The system would launch an instance of this particular activity and then proceed by loading its layout. This would be the major or the home activity of the Android mobile application.

You will then have to design the activity_main.xml file. This XML file deals with the definition of the various activities ’ UI. You can find this XML file in app->res->layout-activity_main.xml that would possess the entire layout of the mobile application.

The next major file would be the manifest file of the application. This is very critical as it would contain all the fundamental information and characteristics of the application with the version of packages, the version of SDK, and the components defined.

As a developer, you would also notice two files with the name build. gradle. One would be for the entire project while the other would be only for the ‘app’ module. One thing that is noticeable is that every module must be built in a .gradle file, while there will be one gradle file for the entire project.

What Are the Fundamental Components of the Mobile Application?

Activities:

This, being the most fundamental block of the android application, you will have to define this as an entry point for all the user’s interaction with an application that includes navigation as well. Implementation of the activity can take place easily as a subclass of the Activity class. 

This would provide the way for the app to get used to the user flows present between them. It would also help in keeping track of what the user currently does on a particular screen. You can know more about the possible operations of Activities with the state flows here.

Services:

This is a major application component that has the ability to do all long-running operations at the background level without the user interface. 

The best example would be a service designed for the purpose of handling network transactions, music playing, performing the file operations all from the background without the user interface. For creating service, the developer will have to first create a subclass of the Service or any of its already existing subclasses.

The most important callback methods that should be overridden are as follows:

  • on Start Command() – This callback method gets invoked by the system by calling the start Service(). You will have to ensure that the service is stopped by either using stop Self() or stop Service().
  • on Bind() – Here this method gets invoked by calling the bound Service() when there is a need to bind with another component. In case you don’t need to allow binding, the null option should be returned.
  • on Create() – This callback method gets invoked in order to do the single time setup method when the service gets initially created. 
  • on Destroy() – This gets invoked when a particular service is no longer needed and destroyed. You must be declaring a service in the manifest similar to declaring the activities and components. The Declaration of the Service is shown in the below figure.

Broadcast Receivers –

This is a component that helps the system in providing the events that are different from the regular flow ensuring the app responds to the system. The broadcast receiver gets implemented as a subclass of the main Broadcast Receiver wherein each of the broadcasts gets delivered as only an object of Intent. 

You can know more about the Broadcast Receiver class, its classes, constructors, and methods here.

Content Providers:

This is a component known for managing all the shared sets of application data present in the system. This is also in regard to the SQLite database. With the help of this, the other applications can query or do any modification to data. 

One example would be the Contacts Contract. Data content provider whose major function is to read and write the information about a specific person. This is implemented as a subclass of the Content Provider and should definitely implement the API’s

How To Develop Android App?

The initial step would be to set up the workspace to develop android application. This can be done by opening the app->res->layout->activity_main.xml. 

The developer then needs to press the design tab located at the bottom and then further press the blueprint option. You can then select the default margins and also click the device for the preview on the screen.

You can add the text box by pressing the Text View present in the Component Tree window and can also add the plain text to it. From the palette, you can choose the buttons wherein you can drag and drop and constitute towards a more intuitive user interface of the application. 

In addition, you can also select the design surface and then select Design. This can be done by opening the app->res->value->strings.xml. This would be the string resources file wherein you will be able to specify all the UI strings. All these will help you to develop a simple and intuitive user interface with specific layout designs.

You can also contact android app development company 4 Way Technologies to get your android app developed faster.

The Android Application’s Manifest

The developer has to know that every project must definitely contain an Android Manifest.xml file. This will present at the root directory of the project and will be containing the necessary information about the application. 

You can know more about the android manifest element reference. The manifest file must contain the application’s package name matching with the namespace. All the components of the applications that include services, broadcast receivers, content providers, and the activities must be declared in the manifest file. 

Another major part of the manifest file is that all the permission the application would need in order to access all the protected parts of apps is declared. The following is a sample of the entire android manifest file.

Running the Android Mobile Application

Once the Android app gets completely developed and successfully tested with all its functionality, it can be launched. There is a possibility of running the application developed on the device as well as on an emulator. To run the application on the device, you will have to do the following steps:

  1. Connect the mobile device to the machine which is specific for the deployment purpose. This can be done with the help of a USB cable. 

    The next step will be to enable the USB debugging mode in the developer options present.
  2. The development mode can be enabled by opening the Settings->System->about the phone. You should then scroll through the bottom and select ‘About phone’. After which you should select the Build number 7 times continuously to enable the USB debugging mode.

In the Android Studio, you will have to choose the app module and then choose the Run option. This should be followed by selecting the deployment target device.

To run the Android application developed on an emulator, choose the app module -> then press the Run option. You can then choose the hardware, a phone device can be chosen. Then from the list of system image screens present, you can choose the one with the highest API level for the best quality of the application. You can also know furthermore about running the application.

Conclusion

We hope that you found this tutorial helpful. Now, you would be able to design and develop Android app using the Android Studio development environment with the help of this guide. Please provide your valuable feedback in the comment section below.

You can easily download the specific version of JDK for your machine and run it. The Android Studio which serves as the official IDE for Android code and projects can be used here for developing the applications.

For building the application, the developer has a variety of options that include the following- Amazon creator, Fire App Builder, the Web Application Starter Kit, the custom Android application, custom web application, and the games application. 

The developer can choose from one of these for the development of the application based on the purpose of the app and the skillsets of the developer.

During the development of the Amazon Fire TV App, the developer can also try implementing the Amazon APIs in order to create a much more robust experience. The In-App Purchasing API concept and the Amazon Fling SDK enable the customers to experience a more robust experience of the Amazon Fire application created. 

The Web application starter kit for the Amazon Fire TV can be used if the developer is a web application developer whose purpose is to build a media streaming application.

2. Development of the application using the Fire App Builder

The amazon fire tv developer will need to ensure that the latest version of the Android Studio is available, the Java Development Kit (JDK) version 8 or later is available on the device they are working on. The developer will also need the Fire TV or the stick for testing the functionalities of the application created for the Amazon Fire TV. 

The Fire App Builder provides an extensive range of features that help in building a highly intuiting application for the end-users. The critical features provided by the Fire App Builder are as follows. 

The Five screens are the most important features provided by the Fire App Builder. The major screens include the splash screen, content detail screen, search screen, content renderer, and home screens. The key steps involved in developing the Fire TV application are as below

3. To get started with the Fire App Builder for building an app for the Amazon Fire TV

The sequence of steps involved in setting up the environment includes downloading and building the sample application using the Fire App Builder. 

This must be followed by connecting through the ADB (Android Debug Bridge), ensuring enough knowledge is gained by taking an application tour, gaining hands-on experience with the Alexa Integration process and making changes, testing the features and functionalities by customizing the sample project. 

You can know more about the features and highlights of the Fire App Builder through the image below:

4. Configuring your Feed section

The developer will have to load the media feed inclusive of the images or the video files required. The next step will be to set up the category recipe and completely configure it. You can find more detailed steps of setting up the category’s recipe, customizing with the query parameters. The next important step will be to find the match list parameters with the query parameters.

This is followed by setting up the contents recipe and finally completely configuring the navigator for the application to be built. You start with loading the media feed and then configuring it. 

The feed would contain all types of media assets such as titles, descriptions, and various media objects. For the purpose of loading, configuration the feed, the developer needs to efficiently use the queries to target specific information elements in the feed. 

The results are then later mapped to the Fire App builder model. The basic flow of the Fire App builder would be like the image below:

5. Customizing the appearance

The appearance of the application can be changed by altering the applications’ logo or the icon. The Home screen appearance, the layout can be changed. The home screen for the application can be changed to a different look by customizing the home screen

The best part is that the customization can be done to every element of the application inclusive of the font, background color, the layout, screen customization by modifying the changes to the application custom.xml. File.

6. Addition of the Components for more Functionality

Fire App Builder enables the inclusion of the components for the purpose of authentication, the analytics, the media player, and the advertisements. It is possible that only one component can get loaded of a particular interface type. 

Addition or the removal of the components can be done by editing the lines in the Gradle build files of the application. Each component of the application would have a set of specific instructions for the purpose of configuration.

7. Adding the recommendations

The recommendations play a very critical role. They allow the view of the media files to the users. The media tiles generally have information about the content in the feed. They appear on the recommended section of the Fire TV home screen. These recommendations play a huge role in encouraging users to use the application.

8. Testing and Submission of the Application to the Amazon app store of the Amazon Fire TV

Once the application is completely developed and tested for the Amazon Fire TV, you will have to submit it to the app store for use. The foremost step will be to completely interpret and understand the Amazon Appstore submission procedure. 

You need to ensure that you have an Amazon customer and developer account. The submission of the application to the app store is more like as shown in the image below:

Develop a Fire TV App

The application developer must comply with the content policy of Amazon. Additionally, screenshots of the developed application must be provided for the purpose of promoting the application on the Appstore. 

The following are the brief steps involved in the submission of the application to the Appstore.

  • Develop or migrate the application – The developer needs to ensure that the application is either created from scratch or gets migrated for the purpose of getting published in the Appstore.
  • Testing of the application – It is very critical to check whether the application meets the criteria of the Appstore and comply with the various policies of the Amazon app store. Additionally, Amazon also provides testing services in order to validate the application’s functionalities.
  • Submission of the application – You will have to log in to your developer Amazon account, enter the necessary information and then upload the application.
  • Responding to any failure notification – There can be situations where the application fails to meet any submission criteria, for which you would receive the failure notification. This will help to a great extent in fixing the application and then resubmitting it to the app store.
  • Updation of the application – The developer gets the chance to update the application by making some changes to it when the app is being live in the app store.

And finally, We are done!
