推荐答案

由于直到API才引入KeyboardShortcutGroup，您可能需要将目标android版本(在使用Android版本编译"下的Android项目属性内)增加到API 24. 24.

You may need to increase your target android version (within the Android project properties under Compile using Android version) to API 24 since KeyboardShortcutGroup was not introduced until API 24.
