我在应用程序中有一个ANR问题。我有两个我正在测试的设备（htcm8和一个三星tab3），我无法重现这个问题。
我的应用程序有几个片段（~10），大多数都做asynctask所以我怀疑某处有锁，但我不确定。我通过一次真正启动多个线程（asynctask）进行测试，并让它们尽可能长时间运行，我从来没有得到ANR。
我的主要问题是ANR的堆栈跟踪非常难以阅读和理解（崩溃更容易:)）。是否有一些指导从哪里开始。
我查看了stackoverflow，这是一些很好的东西，但我没有关于我们应该寻找的东西的详细白皮书？由于我不进行调试（ANR发生在远程站点），有什么要看的东西？
https://developer.android.com/training/articles/perf-anr.html没用？
以下是GetInfoWan.java的第166行：
ipwan = new GetIP_WAN().execute("127.0.0.1").get();
以下是我的追踪示例。看起来有很多asyctasks同时运行，但我找不到“等待锁定”。

答案 0 :(得分：0)
问题是get（）方法，它将在AsyncTask完成之前阻塞。 AsyncTasks具有有限的线程池大小，因此如果还有许多其他AsyncTasks，则在GetIP_WAN AsyncTask完成之前，您必须等待其他任务完成。
你应该做的不是使用get（），而是覆盖AsyncTask中的onPostExecute方法来获得结果。
