First, you need to create your environment in order that your desktop is prepared to aid your Android development goals. For that, you may need Android Studio and the Android SDK.
Android Studio is an IDE, which is essentially an interface wherein you can enter your code and access all the different tools necessary for development. Android Studio helps you to get, access to the libraries and APIs from the Android SDK and thereby providing access to the native functions. You’ll also be successful to build your app into an APK with the use of Gradle, test it through a virtual device, and debug your code even as it runs.
3. Start a new project
Once you’ve Android Studio on your machine, the next step is to start a new project. Go to File > New > New Project. Now you may be asked to select a Project Template. This defines the code and UI elements with a view to be included in your new app when it loads.

Kotlin is probably the language of choice for Android developers that are learning for fun, or that haven’t any aspirations to develop for other platforms.
5. Familiarize yourself with the files
There are just so many different files, folders, multiple types of code, and more. The file that is open MainActivity.java or MainActivity.kt. The main file for this activity is going to outline how your app behaves. Look at the left, and you may see that this file is found in: MyApplication > app > src > main > java > com > name > my application. The folders are vital for Android development, as they assist Android Studio and Gradle to find its entirety and build it correctly.
6. Test your app
The first thing that you are supposed to do when familiarizing yourself with any new programming language, and to create an app.
If you look at the controls along the top, you will see there is a touch of green play arrow. When you installed Android Studio, you ought to also have installed an Android system along with the AVD Manager. You already have an Android emulator to set up and ready to go. By clicking on this green arrow, you will be capable to launch and test your app. You can change the settings for your virtual device – such as Android version, screen size, space, etc – by going to Tools > AVD Manager. Make sure that your virtual device meets or exceeds the minimum SDK you place at the start.
77% of Americans own smartphones and apps are wherein the majority of their time is spent. In fact, the apps have been downloaded, making sure that a profession as an Android App Developer is solid, one with lots of possibilities for growth.
