I'm porting an iPhone app to Android and I can't seem to find a means to pop each activity on the stack except the root activity.
In objective-c I would do something like the below
[navController popToRootViewControllerAnimated:YES];
Anyone know if I can effectively call "finish()" on each activity after some action?
If you want to start one Activity, say, your homescreen, and remove every other Activity in your application's stack, you can use:
Intent intent = new Intent(this, MainActivity.class); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); // Removes other Activities from stack startActivity(intent);
If you also want to provide this event in the MainActivity (such as a logo click in the title bar), you can add the FLAG_ACTIVITY_SINGLE_TOP
flag as well to make sure it does not add another instance of itself to the stack.
