import android.os.Bundle;
import android.widget.Toast;

public class ActivitylifecycleActivity extends Activity {

    void mt(String msg) {
       
        Toast.makeText(this, msg, Toast.LENGTH_LONG).show();
    }
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
       
        mt("On Create");
    }
   
    @Override
    protected void onStart() {
        super.onStart();
       
        mt("On Start");
    }
   
    @Override
    protected void onResume() {
        super.onResume();
       
        mt("On Resume");
    }
   
    @Override
    protected void onPause() {
        super.onPause();
       
        mt("On Pause");
    }
   
    @Override
    protected void onStop() {
        super.onStop();
       
        mt("On Stop");
    }
   
    @Override
    protected void onDestroy() {
        super.onDestroy();
       
        mt("On Destroy");
    }
   
    @Override
    protected void onRestart() {
        super.onRestart();
       
        mt("On Restart");
    }
}
