What are these log messages ？ Do I lack the actual application here logcat journal ？

Yes , You are missing a log , This indicates that some messages are not placed in the actual log , It may be that other applications send too many messages to it .

` It seems to be Marshmallow（？） in liblog New things in the world . No clear explanation was found for the new logging policy , Even if there is actually an explanation , But this change is mentioned here ：

Once the application records 5 More than content , We declared the application too talkative Wait a second . Please raise an error for the application owner , Generating class logging spam at this developer verbose debug level . journal The size is 256KB, This means that the application is creating DOS attack , Reduce the log time span to 6 second （！）, Make it invalid for all other logs .

Once the application is logcat Think it's “ Chat ”（ Exceeding every second 5 That's ok ）, Your application log will be collapsed .

• Put my app on the white list :

adb logcat -P "45678"

• You can disable this behavior in the following ways ：

adb logcat -P ""

• Shows that I have whitelisted my application

adb logcat -p
45678 (the UID of my app)

perhaps

setprop ro.logd.filter disable

setprop persist.logd.filter disable
