Merge "Revert "Fix touch focus not updated correctly after launching overview...

        mTarget = activity.getDragLayer();

        mTarget.getLocationOnScreen(mLocationOnScreen);

        // When Overview is launched via meta+tab or swipe up from an app,

        // the touch mode somehow is not changed to false by the Android framework.

        // The subsequent key events (e.g. DPAD_LEFT, DPAD_RIGHT) can only be dispatched to

        // focused views, while focus can only be requested in

        // {@link View#requestFocusNoSearch(int, Rect)} when touch mode is false. To note,

        // here we launch overview with live tile.

        mActivity.getRootView().getViewRootImpl().touchModeChanged(false);

    }
