Understanding Android Activity Lifecycle

The Android Activity lifecycle is a sequence of states that an Activity goes through when it is created, paused, resumed, and destroyed. The key methods to handle are:

    onCreate()
    onStart()
    onResume()
    onPause()
    onStop()
    onDestroy()
  

Each of these methods is called at different stages of the Activity's lifecycle.

Example:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
