I'm quiet a noob in regard to logcat. I got it to work and my logs seem to be usable but I don't realy know what I did.
Based on endles reading and trying I figured out that that I can retrive logs as soon as logcat viewer is connected to my phone. There are multiple viewers on available as disussed in stackoverflow- android desktop log viewer
or do it only by the means of ADB (in conjuction with LineageOS bug report
Furthermore I found good explanation aboute the log levels
and message types
But what do you do when you on the move with phone. I know there a plenty of apps. I used aLogcat root but it exported only a fraction of the live log, whyever?
allowed me to save huge logs what began before I connected it to a desktop PC. I cannot explain how that is possible sine any other viewer shows only live logs and may shows only a limited number of log entries.
So I would like to know how is the loging process started and how it is ended. Is there any command or does an logcat app need to run. If an app is neccesary, does it have to run in the foreground or background?
