In fact, the famous American technology columnist and writer David Pouge renamed smartphones as app phones to distinguish between the earlier smartphones with lesser applications to the modern-day phones available with millions of applications.
Android – The Wonderful Operating System
Android is an open-source mobile Operating System developed by Android Inc. which was before the release of the OS, it was taken over by Google. It is developed on a modified version of Linux and a few other open-source software. It was solely meant for mobile app development but now it has taken over the market for applications on wearable devices and smart TVs as well.
What are the Steps for Developing A Basic Android Application?
1. Install Android Studio
The first step is pretty obvious, to develop android application first step should be to Install Android Studio. While downloading one needs to make sure that it is from Android’s original site and all the requirements for hardware and software meet.
2. Download Java Development Kit (JDK)
Make sure you have JDK installed in your system for Java. If not, go ahead and install it. If you already have you’re good to go ahead.
3. Opt for new Project
When the setup is done choose ‘Start a new Android Studio Project’. Choose a name that will appear at the store for your application and a ‘domain’ for your company if you’re acting as an individual you can choose something else but decent. This is how it’ll appear: com.companyname.appname. This represents the APK (‘Android Package File’) that will be uploaded to the Google Play Store.
4. Choose an Activity
The next step will be about choosing how you want your application to look like. The first ‘Activity’ you choose will represent your application’s main screen. There are various modules available at Android Studio, you have to choose according to the need and the idea of your application. There are full-screen activity, blank activity, etc. But as for the beginners, it’s better to go for ‘Basic Activity’ to keep things simple. Make sure the selected language is Java and not KOTLIN.
5. Choose the desired Layout
After choosing the required activity, comes the part to select a layout name for the chosen activity. The layout will define where the elements like images and menus go and what fonts will be used and visible to the end-users.
6. Edit the textbox according to your requirement
The next step will be about editing, moving, stretching the textbox and other available widgets as per your plan and your applications. When you choose a widget that comes with the default texts, you need to edit the texts, the size, the colour as per your plan of the application.
7. Add buttons and widgets as per your and application’s need
This step is about drag and drop of all the widgets and buttons you need in your application, and renaming them, editing them, adjusting them.
8. Code for the Backend
Here, comes a bit of a complex part that is the backend coding. You need to fill in the details of all the widgets you use with their respective functions. And you have to write a code for what your application will do. Android Studio provides code suggestions, so you don’t have to worry much about it.
9. Test Run on Emulator or connected Android Device
The last step is always about execution. After you think your application is ready, test it to make sure it’s working the way you have planned.
