Android Closing Program Activities

Question

What is the equivalent operation in action to move from the screen. For example, when you click the back button, the action disappears from view. How can this be called from within the action so that it closes.

Answer 1

What about the Activity.finish() method:

Call it when your activity is completed and must be closed.

Answer 2

you can use this.finish () if you want to close the current activity.

 this.finish() 

Answer 3

Method

finish () is used to complete the operation and remove from the previous stack. You can call it in any way in action. But make sure that you close all database connections, all reference variables are null, to prevent memory leak.

Answer 4

you can use finishAffinity(); to close all actions.

Answer 5

 finish(); OR System.exit(0); 

I think this will help.
