我得到了一个电话管理器的实例（单或多卡设备）并得到了几个 ANR。我已经设法完成了其中的大部分工作，但这个仍然存在：

*意图广播{act=android.intent.action.SCREEN_OFF flg=0x50000010（有额外内容）

处理这个问题的最佳方法是什么？其中一些只有在打开应用程序并打开设备屏幕几个小时后才能重现。这使得调试诸如此类的 ANR 变得困难。

报告中有一部分说运行被“锁定”。如何区分这是死锁还是线程正在等待当前操作完成？callbackDataConnectionStateChanged()、refreshTelephonyState() 方法是同步的
