Android Activity Lifecycle and Explanation of Each Callback Method

Android Activity Lifecycle refers to the different states an activity goes through during its lifetime. There are several callback methods provided by the Android system to manage the activity lifecycle:

1. onCreate(): This method is called when the activity is first created. It is used for initializing essential components of the activity.
2. onStart(): This method is called when the activity becomes visible to the user. It is typically used for preparing the UI to be visible.
3. onResume(): This method is called when the activity is about to start interacting with the user. It is used for activities that require user interaction.
4. onPause(): This method is called when the activity is going into the background, but is still visible. It is used to stop ongoing actions and save data.
5. onStop(): This method is called when the activity is no longer visible to the user. It is used for releasing resources that are no longer needed.
6. onDestroy(): This method is called when the activity is being destroyed. It is used for releasing resources and performing cleanup operations.

Understanding the Android Activity Lifecycle and its callback methods is crucial for properly managing the lifecycle of an activity and maintaining a smooth user experience.
