I have an issue when i'm moving from the portrait mode to landscape mode on mHandler.removeCallbacks(mShowContentRunnable);
the onDestroyView is under a class that extends ProgressFragment
How i can fix it?

@Override
public void onDestroyView() {
    super.onDestroyView();
    mHandler.removeCallbacks(mShowContentRunnable);
}

Here my error log
