  2. Click on the "File" menu and select "New" > "Java Class" (or "Kotlin Class" if you're using Kotlin).

    public class MyActivity extends AppCompatActivity {
 @Override
 protected void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.activity_my);
 }
}

  6. Create a new layout file for your activity by right-clicking on the "app/src/main/res/layout" directory and selecting "New" > "Layout resource file".

  7. Name the file "activity_my.xml" and add the following code:

    
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:orientation="vertical">

 <TextView
     android:id="@+id/textView"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:text="Hello World!" />
``` That's it! You now have a new empty activity in Android Studio.
