我的 Android 应用程序出现 ANR 错误。

它的踪迹在下面

“main”和“Thread-20153”是 ANR 的主要问题？

但我不知道问题代码在哪里。

如何解释这个？

痕迹太长，问题太幼稚。您不必解释整个错误，只需告知如何解释主题即可。

到目前为止，它看起来没有问题。正如我们在这里所看到的，主线程被暂停，另外一个称为 WebViewCoreThread 的线程也被暂停，除了这两个之外，其他所有线程似乎都很好，无论是进行经典等待还是定时等待或只是运行。

这里可能发生 ANR 的 2 个可能原因可能是因为 2 个线程中的任何一个被无限期挂起，并且 android（系统）在等待一段时间后会认为它们已经死了，比如几秒钟，因此抛出了 ANR .

您可能想检查这些线程中是否有任何断点，或者这些线程中的任何一个正在执行一些涉及实例化导致 gc 的对象的繁重操作，这也可能导致线程进入挂起模式。

还要检查日志看门狗杀死任何系统进程的任何迹象..可能有助于解决这个问题！

您应该检查 TIMED_WAIT 线程，为什么每次尝试锁定不同的主题？是什么导致了这种情况发生？ - waiting on <0x40e0b258> (a java.util.Timer$TimerImpl)
