Android Studio Internal Details

Android Studio is a powerful Integrated Development Environment (IDE) used for developing Android apps. It is built on the JetBrains IntelliJ IDEA software and is specifically designed for the Android platform.


Android Studio uses the Java programming language with the Android SDK (Software Development Kit) to create Android apps. Java is a high-level programming language that is used to write code for Android applications.


public class MainActivity extends Activity {
    protected void onCreate(Bundle savedInstanceState) {
        // Do something here


The output of the above code is the creation of a new activity that displays the layout defined in the activity_main.xml file.


The MainActivity class extends the Activity class, which is the base class for Android activities. The onCreate method is called when the activity is created and is used to set up the activity's user interface.

The setContentView method is used to set the layout for the activity, which is defined in the R.layout.activity_main file. This file is stored in the res/layout directory of the Android project.


Android Studio is used to develop Android applications. Developers can use the IDE to write code, debug, test, and deploy their apps to the Google Play Store.
