how to finish all activities and close the application in android?

My application has the following flow:

Home->screen 1->screen 2->screen 3->screen 4->screen 5>Home->screen 2->Home->Screen 3

My problem is that when I am trying to close the application then Home activity opens everytime when I am trying to close the application.

I just want to close the application when user presses the back key of device on home screen.

Hi if you are in a fragment and are not able to use the finish method as it is(because finish should solve your problem) then you can use the getActivity.finish() method after startActivity(intent);. If you are not in a fragment you could directly use finish() after you startActivity(intent); line

There is finishAffinity() method that will finish the current activity and all parent activities, but it works only in Android 4.1 or higher.

Use finishAffinity() method that will finish the current activity and all parent activities. But it works only for API 16+ mean Android 4.1 or higher.

API 16+ use:

finishAffinity();

Below API 16 use:

ActivityCompat.finishAffinity(this); //with v4 support library

To exit whole app:

finishAffinity(); // Close all activites
System.exit(0);  // Releasing resources

Sometime finish() not working

To clear all the activities while opening new one then do the following:

Intent intent = new Intent(getApplicationContext(), YourActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

This works well for me.

  • You should using FLAG_ACTIVITY_CLEAR_TASK and FLAG_ACTIVITY_NEW_TASK flags.

    Intent intent = new Intent(SecondActivity.this, CloseActivity.class);
//Clear all activities and start new task
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK); 
startActivity(intent);

  • onCreate() method of CloseActivity activity.

    @Override 
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    finish(); // Exit 
}

You can try starting the Screen 3 with Intent.FLAG_ACTIVITY_CLEAR_TASK http://developer.android.com/reference/android/content/Intent.html#FLAG_ACTIVITY_CLEAR_TASK

There are 2 ways for solve your problem

1) call finish() after startActivity(intent) in every activity

2) set android:launchMode="singleInstance" in every tag in menifest file

i think 2nd way is best for solving problem but you can also use first way

Add android:noHistory="true" in your activity manifest file.
