我们的应用程序有时会在设备前景很长一段时间后与ANR锁定，比如过夜。该应用程序启动，但只显示黑屏。 Back和home按钮在按下后大约10秒钟才会响应。
以严格模式运行应用程序，不会突出显示任何问题。所有网络活动和长时间运行的任务都在后台线程上完成。
查看我们应用程序的跟踪文件，我无法识别“主”线程，因此我无法诊断锁定UI的内容。
This question听起来像是相同的症状，但我们的应用程序不使用违规库：JmDNS。

dumpstate文件中的更多信息。 （在/data/log/dumpstate_app_anr.txt.gz上的ANR之后从设备检索）使用Unix用户app_112的应用程序的进程ID是16042。查看更详细的logcat（在文件中搜索MAIN LOG），它看起来像OutOfMemoryException。但我希望JVM能够崩溃并重新启动，而不是在僵尸状态下锁定。什么阻止应用程序成功崩溃？
冻结Android应用的zip file中/ proc / PID /文件夹的详细信息。
答案 0 :(得分：0)
我还没有看到ANR跟踪中的主线程堆栈，它在哪里？
而且，从“java.lang.ProcessManager”堆栈，我猜你正在通过分支子进程来做某事？
之前我遇到过这个问题，在等待子进程退出时，Java进程包装器有时会被阻塞是一个非常奇怪的错误。
我不确定它是一个bug，在我的情况下，我的子进程已经消失，但主进程仍然在主线程中等待它。然后ANR发生了。
最后，我编写了一些JNI代码来包装C库“system（”cmd“）”来解决这个问题。
