我正在开发一个动态壁纸，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动态壁纸设置为壁纸时，会抛出一个异常，说“注册输入失败频道。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。
知道是什么原因导致了这个问题，或者我该如何解决？
【问题讨论】：
-
(1) 你检查过“日志”吗？ (2) 堆栈跟踪中是否有以“caused by:”开头的第二轮？
-
@Aleadam 不，只有一轮堆栈跟踪。我发现与此问题相关的唯一日志是“在没有当前上下文的情况下调用 OpenGL ES API（每个线程记录一次）”，正如我在上面列出的那样
-
@Aleadam 也“输入通道未初始化”
-
@Aleadam 我发现这是因为我使用启动器 pro 进行测试，当用户单击“设置壁纸”按钮时，它不会释放 OpenGL ES 当前使用的硬件
