Warning when canceling ActionBar Overflow menu on Android 4.1.x

This is not related with your work.

Overflow menu is implemented by PopupWindow. When user touch to close PopupWindow, ACTION_DOWN event queued to app's Message queue. Then it is delivered to View through ViewPostImeInputStage class and finally ViewPostImeInputStage send this input event to PopupWindow's onTouchEvent listener.

    @Override    public boolean onTouchEvent(MotionEvent event) {        final int x = (int) event.getX();        final int y = (int) event.getY();        if ((event.getAction() == MotionEvent.ACTION_DOWN)                && ((x < 0) || (x >= getWidth()) || (y < 0) || (y >= getHeight()))) {            dismiss();            return true;        } else if (event.getAction() == MotionEvent.ACTION_OUTSIDE) {            dismiss();            return true;        } else {            return super.onTouchEvent(event);        }    }

dissmiss() try to close PopupWindow and PopupWindow::onDetachedWindow call WindowInputEventReceiver::dispose() first.

And then ViewPostImeInputStage call WindowInputEventReceiver::finishInputEvent to finish that ACTION_DOWN event. However WindowInputEventReceiver instance is already disposed so it throw warning messages.

You can debug it by breakpoint. open InputEventReceiver.java(need android source code at framework/base/) and set breakpoint at dispose method.
