在代码中我们经常看见ProtoLog打印的log#xff0c;如下#xff1a;
ProtoLog.i(WM_DEBUG_ANIM, Animation start delayed for %s, mAnimatable);这种log正常情况不会显示#xff0c;因此我们需要打开开关#xff0c;其格式为#xff1a; adb …ProtoLog开关
在代码中我们经常看见ProtoLog打印的log如下
ProtoLog.i(WM_DEBUG_ANIM, Animation start delayed for %s, mAnimatable);这种log正常情况不会显示因此我们需要打开开关其格式为 adb shell wm logging enable-text [代码中对应的TAG] 我们这段代码的TAG是WM_DEBUG_ANIM因此通过命令adb shell wm logging enable-text WM_DEBUG_ANIM打开log开关
logcat抓取log
# 抓取普通的andorid log
adb shell logcat log.txt
# 仅抓取events log
adb shell logcat -b events log.txt
# 抓取所有类型log
adb shell logcat -b all log.txt# 根据关键字抓取log-i可以忽略大小-e可以添加多条关键字如下
adb shell logcat -b events | grep -ie 关键log1 -ie 关键log2 log.txt
events.log中对应代码查找
events log对应代码的规律是 events log开头的字段比如wm_xxx 则对应的代码可以通过 grep 抓取 writeWmxxx 找出是在哪里打印的该events log
例如 应用走到onresume生命周期的log wm_on_resume_called: [223605563,com.tencent.mm.ui.LauncherUI,RESUME_ACTIVITY,10]
EventLogTags.writeWmOnResumeCalled(mIdent, getComponentName().getClassName(), reason);通知cancel的log notification_canceled: [0|com.tencent.mm|40|null|10218,8,19980,19980,7720,-1,-1,NULL]
EventLogTags.writeNotificationCanceled(canceledKey, reason,r.getLifespanMs(now), r.getFreshnessMs(now), r.getExposureMs(now),rank, count, listenerName);
