Cannot close android activity

Question

I have an application with an activity (activity1) that pauses when pressing a button, opening a new activity (activity2) that has two buttons: a menu button and a button to resume the activity1. Pressing the menu button that opens a new activity (activity3) that has a button to get out of the application but instead of closing, it goes back to activity1, restarting it. How can I close the aplication or close the activity1 inside the activity 2 or 3?

Sorry my English. thank you very much

When you call your activity, call finish(); straight after:

Intent intent = new Intent(getApplicationContext(),MyActivity.class);
startActivity(intent);
finish();

This will run your new activity, and close the old one in the process.

But I what to pause activity1 when I pass to activity2. And when I change from activity2 to activity3 I finish activity2. But activity1 is paused on background and I want to finish it when I try to System.exit();. – user1491548 Aug 01 '12 at 12:52
If you close activity 1, (and 2?) Then when you click the button to close activity 3 (`finish();`), the whole application will close, as there are no longer any activities on the stack. Or see @userSeven7s answer. Actually, yes. Follow userSeven7s answer, I missed that you wanted to resume activity1 in some scenarios. – IAmGroot Aug 01 '12 at 13:13

Pressing the menu button that opens a new activity (activity3) that has a   
button to get out of the application but instead of closing,   
it goes back to activity1,restarting it.

Closing a Activity from other activity?? Not Possible.
But you can achieve it(manually) by setting a Global Variable..

Like when you press Exit Button in Activity-3,set a Global variable(int),say "int exit" and call finish() in Activity 3,this will land you in Activity-2..Now in the OnResume Method of the Activity-2 and Activity-1,Go On to Check the value of the Global Variable,if exit== 1,call finish() there.else do nothing.

You can create a class that would extend the class Application..there you can Declare variables and use there Values any where in any Activity. – Haresh Chaudhary Aug 01 '12 at 12:56

Use startactivityforResult to start your second activity.
In second activity, when you press exit menu button, finish the activity with result code 1..
In onActivityResult of first activity, check the result code.. if its exit code(1) then call finish...

This ^^^. Starting both activities from Activity1 would give you more control over what's happening. It doesn't sound like you actually WANT the activities to stack so this would work well. – DeeV Aug 01 '12 at 13:04
I'm not understanding the third step! – user1491548 Aug 01 '12 at 13:16
