我正在开发一个 Livewallpaper，它使用一个名为 Andengine(andengine.org) 的开源游戏引擎，它现在工作正常，除非有时当用户将我的 Livewallpaper 设置为墙纸时，会抛出一个异常，说无法注册输入频道.查看日志以获取详细信息."，但奇怪的是动态壁纸仍然有效并且没有退出.

I was developing a Livewallpaper which uses a open-source game engine called Andengine(andengine.org), it works fine now except sometimes when user set my Livewallpaper as wall paper, an Exception will be thrown saying "Failed to register input channel. Check logs for details.", but the werid thing is the Livewallpaper still works and did not exit.

知道是什么原因导致了这个问题，或者我该如何解决?

Any idea what maybe causing this problem , or how I can fix it?
