how to stay app open when the user press back button

Question

I want to create an app with this ability:when the user press back button.don't close app & stay in running list in settings->application manager->running
& stay in running list when user press home button too.

I like to make an app that there isn't in task manager->active application but there is in settings->application manager->running such as Viber,Tango,Gmail

use a receiver and run something in background to maintain your process stays running.Override backpressed in your class to handle its click. — hemanth kumar, Feb 04 '14 at 12:32

Add onBackPressed() into your Activity:

@Override
    public void onBackPressed() {
     moveTaskToBack(false);
  }

you can achieve it as follow:

@Override
public void onBackPressed() {
    moveTaskToBack(false);
}

to minimize your app use moveTaskToBack(true);

NOTE: don't write super.onBackPressed();

moveTaskToBack(false); `true` will close the application or activity while OP has asked not to close the activity. – user3264399 Feb 04 '14 at 12:32

welcome, just to add one more thing that above code doesn't minimize the application. – user3264399 Feb 04 '14 at 12:34
but with this code app stay in task manager too & when the user press end my app will be close. but there are many app that there aren't in task manager but are running how can I do it? – user3257386 Feb 04 '14 at 12:51
this is another question. But as per my knowledge no one can make an app that is not killed by the app manager. – dinesh sharma Feb 04 '14 at 12:54
Even if you write a background service to wake up your app the app manager will also kill the service. – dinesh sharma Feb 04 '14 at 12:56
ok I know it.but I like to make an app that there isn't in task manager->active application but there is in settings->application manager->running such as Viber,Tango,Gmail – user3257386 Feb 04 '14 at 13:05
They show it in the running because they have background service running but the app may have closed – dinesh sharma Feb 04 '14 at 13:44

Why do you need to keep your app running? If you need to process data while the user is not in your app, you need a Service:
