该类的方法是这样的：

在具有AndroID 4.4的手机上发现了这个问题.在许多其他情况下,在其他 *** 作系统版本上,该方法可以正常工作.

解决方法:

对于那些仍然遇到此类错误问题的人来说,这就是我的结论：

经过大量的搜索和尝试我在网上找到的一切,我自己修复了它.我使用DDMS来查看我的设备上运行的当前线程,并看到有一个ASyncTask运行了很长时间但从未停止过.

它似乎正在访问主线程正在访问的’某事’,并且在访问了’某事’一段时间后,两个线程碰撞导致应用程序挂起导致ANR异常.

我所做的是删除ASyncTask,而是在应用程序启动时(启动时)执行“一次性” *** 作,确保它将运行一次,而不是更多.

我真的建议使用DDMS来查看当前线程,因为ANR通常是由同步/并发问题引起的.

如果您收到此错误,请随时与我联系.
