ANR keyDispatchingTimedOut

我遇到了应用冻结的一些问题。看起来它与hardwarerenderer有关，也许与我正在使用的线程数量有关。我喜欢有人看看日志，并告诉我是否有任何明显的指出。感谢。

ANR是众所周知的问题。确保您在AsyncTask中执行所有昂贵的操作，并且不要对onCreate，onStart或onResume活动负担过重。

请查看Responsiveness以获取更多信息。

  

特别是，活动应尽可能少地设置关键生命周期方法，如onCreate（）和onResume（）。潜在的长时间运行操作（如网络或数据库操作）或计算上昂贵的计算（如调整位图大小）应在子线程中完成（或者在数据库操作的情况下，通过异步请求）。但是，这并不意味着您的主线程在等待子线程完成时应该阻塞 - 也不应该调用Thread.wait（）或Thread.sleep（）。在等待子线程完成时，您的主线程应该为子线程提供一个Handler，以便在完成时回发。以这种方式设计应用程序将允许主线程保持对输入的响应，从而避免由5秒输入事件超时引起的ANR对话框。对于显示UI的任何其他线程，应遵循这些相同的做法，因为它们也受到相同的超时。

答案 1 :(得分：0)

我发现了其中一个ANR错误的非常具体的原因。

在我的应用程序的一个布局定义中，我设置了android：layout_alignRight =“fieldX”

但是在fieldX的定义中，我有了android：visibility =“gone”。

因此显示器试图将字段与不可见的字段对齐。

通过取出fieldX定义的android：visibility线，应用程序开始正常工作而不会挂起。
