Discover how Activities work internally in the Android SDK, including their lifecycle management, intents, and the back stack mechanism. This understanding is crucial for developing efficient Android applications.

<?php
// Example of Activity lifecycle in Android
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initialization code
}
@Override
protected void onStart() {
super.onStart();
// Code to execute when Activity is starting
}
@Override
protected void onResume() {
super.onResume();
// Code to execute when Activity is now in the foreground
}
@Override
protected void onPause() {
super.onPause();
// Code to execute when Activity is partially obscured
}
@Override
protected void onStop() {
super.onStop();
// Code to execute when Activity is no longer visible
}
@Override
protected void onDestroy() {
super.onDestroy();
// Cleanup code
}
}
