Closing App from inner Activity

Question

I have two different activities. The first launches the second one. I want to close the app from second Activity but using finish() the first activity is automatically displayed instead of closing application .How can I avoid this?

Answer 1

As @user3676184 mentioned, you can finish first activity ones you launch second activity. i.e.

Implement this in first activity from where you are launched your second activity.

Intent intent = new Intent(ActivityOne.this, ActivityTwo.class);
startActivity(intent);
finish(); //this will finish ActivityOne and only ActivityTwo will be present and when you call finish in ActivityTwo it will close.

Answer 2

I want to close the app from second Activity but using finish() the first activity is automatically displayed instead of closing application .How can I avoid this?

Because FirstActivity is added in back-stack and pop-up back when pressing back button on SecondActivity.

To get required behavior, after starting SecondActivity call finish() method in FirstActivity to remove from stack :

Intent intent=new Intent(FirstActivity.this,SecondActivity.class);
startActivity(intent);
FirstActivity.this.finish(); //<< close FirstActivity here

Answer 3

when you start second activity from first activity then call method finish() like,

Intent i = new Intent(FirstActivity.this,SecondActivity.class);
startActivity(i);
finish();
