Android 活动冻结，需要帮助解释日志

Question

已与调用 mSurfaceHolder.unlockCanvasAndPost(canvas); 链接起来

这些事件最近 正常返回，而其他人只是崩溃（有时确实使手机崩溃，让我重新启动）。它大约每 1/5 次尝试就会发生一次，而且由于某种原因，我实际上很难用 DDMS 捕获它，因为当我尝试记录/分析它时它根本不会出现故障。

此后，我使用 DDMS 记录了整个冻结期间的以下活动。如果我碰巧遇到我的解决方案，同时我会发回来，对此日志的任何帮助将不胜感激。提前致谢！

还使用加速计、触摸和捕捉按键。所有这些都是在使用 canvasThread 从 surfaceView 进行绘图时完成的。所有这些都与 UI 线程“分离”。

一直试图从崩溃中获取堆栈跟踪，但是当我将调试器附加到它时，该死的事情不会在我身上出现故障；然而，它似乎确实以几乎一半的速率从加速度计获取数据？知道这是为什么吗？

新信息，在使用 DDMS 时，我尝试在冻结时点击“停止进程”，并且它会杀死应用程序一秒钟，然后它会重新出现并毫不犹豫地继续......奇怪
