android - ANR keyDispatchingTimedOut 报告 Google

Question

我得到了“著名的”报告ANR keyDispatchingTimedOut，我正在阅读它，但我不太明白，我想问一下。我猜这个问题是由 onCreate() 上的大量工作引起的？如果我创建一个新方法，我可以避免这个错误吗？这是我第一次遇到这种类型的错误，我有点困惑。

我不知道这条消息的问题在哪里，我的应用程序只有一个主要 Activity 。

非常感谢大家:)

我认为在这里发布您的代码会给您最好的答案，但您可能不了解使用多线程来防止主线程 (GUI) 变得无响应也可能是真的。我发现本教程最有帮助。

这对于刚入门的 Android 程序员来说是一个棘手的问题，即使是有经验的程序员也是如此，但是一旦掌握了窍门，它并没有那么糟糕。
