Tools and libraries that simplify Activities in Android?

    // Example of using Android Jetpack library to simplify Activity management
    import androidx.appcompat.app.AppCompatActivity;
    import android.os.Bundle;
    
    public class MainActivity extends AppCompatActivity {
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
        }
        
        // Manage Activity lifecycles efficiently with Jetpack libraries
        @Override
        protected void onStart() {
            super.onStart();
            // Code to run when the activity is about to become visible
        }
    }
