我有一个已经生产了一段时间的Android应用程序。我收到了一份关于Firebase的致命报告（下面是日志），但我不清楚下次如何避免。
我在java.net.UnknownHostException Unable to resolve host "accounts.google.com": No address associated with hostname while inserting rows in bigquery处找到了类似的堆栈跟踪，但是他们可以通过以下方式解决它：
<uses-permission android:name="android.permission.INTERNET" />
但这不是我的情况。
对于网络通信，我使用：
改造2
好的http 3
用于翻新2的rxjava2适配器
使用此设置，所有错误最终将在rx subscription中的onError函数中结束。我在所有HTTP调用中都处理UnknownHostException，但是即使我不这样做，它也应该报告非致命错误，这是最糟糕的情况。
我不知道如何重现此错误。堆栈跟踪不是很有用，因为它不会将我指向应用程序的任何地方。
关于重现该错误的方法的任何想法以及任何其他见解都将受到赞赏。
这是堆栈跟踪：

手机已断开与网络的连接，并且发生在Android 6.0.1上。
最佳答案
该问题导致嵌套的Rx调用。当我取消一个Rx呼叫的订阅时，嵌套的一个仍然存活并导致崩溃。
