Question

I am using moveTaskToBack() method in my activity.

When I am pressing back button the activity still is visible. The back key does not work. What did I do wrong here? I want to navigate back to the previous activity.

public void onBackPressed() {
    // TODO Auto-generated method stub
    moveTaskToBack(true);
    new Finalizer().killApp(false);
    super.onBackPressed();
}

Answer 1

The purpose of moveTaskToBack:

http://developer.android.com/reference/android/app/Activity.html

moveTaskToBack(boolean nonRoot)

Move the task containing this activity to the back of the activity stack.

What you could do is:

public void onBackPressed() {
    moveTaskToBack(true); // I don't think you're looking for this.
    new Finalizer().killApp(false); // Neither this.
    super.onBackPressed();
}

Maybe this: Android: Go back to previous activity
Something similar in your onBackPressed() after super.OnBackPressed();
Also make sure when you’re hitting your back button, you’re actually going in this method.
