所以我得到我的logcat垃圾邮件这个datarouter错误.谁可以帮助我解决这个问题并告诉我它为什么会发生？
哦,我尝试重新启动手机和日食.
编辑：它似乎主要发生在我的Mac工作计算机上.
以下是每30秒发送一次完整垃圾邮件的日志：

解决方法:
这不是正常的错误,实际上它根本不是错误. Android RIL(特别是在三星设备上)呈现其调试日志是(愚蠢的？)方式.您看到的“DataRouter”,曾经被归类为“Debug”,旧版/其他手机/调制解调器中的标签为“AT”.这对开发人员来说确实非常混乱,并不知道这些变化.很可能是因为三星使用他们自己的协议与基带调制解调器进行通信而不是标准的AT集合,这在某个地方被解释…
一个很好的参考是XDA线程：
