Qt.inputMethod.keyboardRectangle does not work on Android making it impossible to make application to adapt to different sizes when keyboard is shown. Application does resize or be moved so that input usually is visible, but there is no way to know visible size of the window.

This could have been workaround when dealing with QTBUG-40728 but it seems that QAndroidInputContext::keyboardRect() does only return default value (0,0)
