ANR输入调度超时（等待发送非键事件，因为触摸的窗口尚未完成处理500.0ms前传递给它的某些输入事件。等待队列长度：60。等待队列头时代：8503.2ms。）

嗨！我从几个用户那里得到了这个奇怪的ANR报告。不幸的是，我对ANR报告的知识非常有限，我希望有人可以帮助我理解这可能是什么原因

Answer 1

当我有一个循环并且循环有一个增加的条件时，这发生在我身上。我没有设置不符合条件的增量。因此，循环停滞不前。这导致了上述错误。

没有你的代码，我无能为力。但上述情况可能是导致错误的原因。

很显然，您的日志还不完整。它只显示主线程日志，还有什么线程日志。

在主线程中，从"main" prio=5 tid=1 Suspended开始，我们知道该线程已被挂起。在此之前 - locked <0x08f02647> (a android.os.MessageQueue) at android.os.Handler.removeMessages(Handler.java:652) at android.view.Choreographer.removeCallbacksInternal(Choreographer.java:418) - locked <0x0bd41e74> (a java.lang.Object)

您应该搜索日志以检查哪个线程正在等待锁定<0x08f02647>和<0x0bd41e74>，您可能会找到一些线索。
