The Android life cycle refers to the series of stages that an activity goes through during it’s existence.

The stages are important to understand because they allow developers to manage the behavior of an activity and ensure that the user has a smooth experience while interacting with the application.

The stages are:

1.onCreate() : This is the first method called when an activity is created.

2.onStart() : The activity enters the “started” state, indicating that the activity is visible to the user, but not yet in the foreground or interacting with the user.

3.onResume() : The activity enters the “resumed” state, indicating that it is now in the foreground and actively interacting with the user.

4.onPaused() : The activity is about to be paused. This typically happens when another activity is launched in front of the current activity or when the device goes to sleep.

5.onStop() : The activity is no longer visible to the user. It may be either stopped by calling its onStop() method or because a new activity has been started and is covering it.

6.onDestroy() : The final stage of the activity lifecycle. It is called when the activity is being destroyed and is about to be removed from memory.

7.onRestart() : If an activity has been stopped and is about to be restarted, the onRestart() method is called before onStart().
