Answer 1

System.exit() does not kill your app if you have more than one activity on the stack

Use android.os.Process.killProcess(android.os.Process.myPid()); this way.

for sample

public void onBackPressed() {
    android.os.Process.killProcess(android.os.Process.myPid());
    super.onBackPressed();
}

I hope this will help you.

Answer 2

You can use this function to close your application

Process.killProcess( Process.myPid() );
