Question

我正在运行我的应用程序崩溃时获得这些堆栈跟踪。我知道它必须用“ANR keyDispatchingTimedOut”做一些事情。我是Android开发的新手，我需要帮助阅读这些痕迹。

ANR keyDispatchingTimedOut表示您的活动陷入困境，无法对下一个用户输入作出反应。

要读取堆栈跟踪，只需扫描它，直到看到您的包名称，这是您想要专注的位。

之前我曾回答过这个问题：ANR keyDispatchingTimedOut error

ANR错误

活动无响应。

您的活动花了很长时间才对Android操作系统说'嘿，我还活着'！（这是UI线程的作用）。

http://developer.android.com/guide/practices/design/responsiveness.html

基本上，如果你让UI线程执行一些复杂的任务，它就会忙着告诉操作系统它仍然“活着”。

http://developer.android.com/resources/articles/painless-threading.html

您应该将数据库选择/更新/删除代码移动到另一个线程，然后使用回调告诉您已完成的UI线程并对结果执行某些操作。
