【海外场测反馈】【xxx】动态测试时对比机xxxx拨打测试机xxxxx自动挂断电话
工作中遇到一个掉话的问题，需要分析log，log比较大，我也没法上传，就简答的讲讲吧
【Android之mtklog分析】
其实我也不太懂，随便说说吧：
1.
在mobilelog/APLog_2016_0902_134517/radio_log中：
56200:09-02 13:50:59.012418 1570 1570 D CallManager: handleMessage (EVENT_SERVICE_STATE_CHANGED)
mobilelog/APLog_2016_0902_134517/radio_log:56202:09-02 13:50:59.01338815701570 D CallManager:handleMessage (EVENT_SERVICE_STATE_CHANGED)
mobilelog/APLog_2016_0902_134517/radio_log:56586:09-02 13:51:00.57127815701570 D CallManager:handleMessage (EVENT_INCOMING_RING)
mobilelog/APLog_2016_0902_134517/radio_log:57025:09-02 13:51:02.36129815701570 D CallManager:handleMessage (EVENT_IN_CALL_VOICE_PRIVACY_OFF)
mobilelog/APLog_2016_0902_134517/radio_log:57058:09-02 13:51:02.36495715701570 D CallManager:handleMessage (EVENT_IN_CALL_VOICE_PRIVACY_OFF)
mobilelog/APLog_2016_0902_134517/radio_log:57101:09-02 13:51:02.37368615701570 D CallManager:handleMessage (EVENT_PRECISE_CALL_STATE_CHANGED)
mobilelog/APLog_2016_0902_134517/radio_log:60984:09-02 13:52:25.81575215701570 D CallManager:handleMessage (EVENT_DISCONNECT)
mobilelog/APLog_2016_0902_134517/radio_log:61056:09-02 13:52:25.82767415701570 D CallManager:handleMessage (EVENT_PRECISE_CALL_STATE_CHANGED)
mobilelog/APLog_2016_0902_134517/radio_log:62892:09-02 13:52:27.08098115701570 D CallManager:handleMessage (EVENT_SERVICE_STATE_CHANGED)

通过这可以看出从来电到断掉连接
2.在mobilelog/APLog_2016_0901_114539/sys_log:中

可以看出网络连接断开
下面是mtk给的分析结果，因为log中有一些文件只有mtk才有工具能打开查看，我们是看不到里面的内容的，
这次是网络挂断的call，应该是主叫异常导致的。手机处理正常。
