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，除了有时当用户将我的Livewallpaper设置为壁纸时，会抛出异常，提示“无法注册输入通道。检查”记录详细信息。”，但奇怪的是动态壁纸仍然有效并且没有退出。

知道什么可能导致这个问题，或者我该如何解决它？

Answer 1

抱歉，我只能发现 InputQueue “为应用程序提供了一种接收传入输入事件的机制。目前只能从本机代码中使用”。

检查andengine 中的GLSurfaceView 类。这可能会让您了解壁纸有什么问题

您可能还想检查为什么会发生这种情况：
