我在Android 2.2上获得ANR
我在一台设备上注意到它，并认为它只是很慢，但继续尝试优化。现在我在模拟器上尝试了它，所以我可以得到错误日志（因为StrictPolicy在Android 2.2上不可用）而且我确实有。但我也将模拟器推向Android 2.3并且ANR不会发生。
其他事实，ANR在一切都完成加载后发生。应用程序没有停止响应，用户输入和交互将完全正常，没有任何滞后，然后随机ANR将弹出。如果用户点击等待，ANR将不会再次出现，正常运行的应用程序将继续正常运行。
我已经做了很多优化尝试解决这个问题：
现在，它挂起的地方，UI线程中似乎没有任何事情发生，其他线程似乎已经完成了
这是traces.txt，它并没有真正告诉我任何有用的东西，但也许你
