手机端如何输入日志？

[SoDebug]

Google play上下载的，没有发现日志这个选项，，手机端怎么通过终端提取日志？

[vvb2060]

MIUI？
终端的话 logcat -d -s BreventServer >/sdcard/log.txt
然后在内置存储根目录找log.txt文件

[SoDebug]

可他是空的

[SoDebug]

不是MIUI，是360OS

[SoDebug]

然后网易云这些可以识别出来

[vvb2060]

需要ROOT权限……得先执行su

[SoDebug]

我执行了su的

[liudongmiao]

应用并不存在。

[liudongmiao]

你可以播放时，执行 dumpsys media.audio_flinger 以及 dumpsys activity processes。
这两个日志非常大，打包发出来。
