How to clean logs buffer in Android studio?

ANS:  Use adb logcat from command line and pipe the output to a file, since the DDMS has a very limited buffer. At the moment, when I restart my app (after fixing bugs etc) the logcat buffer has data from the previous launch as well. Even uninstalling the app does not clear the buffer. The only way I've found so far to clear the buffer, is reboot. This is effective, but would like to know if there's an easier way.

Why do we need to clean buffer before running logcat ?

ANS: Logcat is a command-line tool that dumps a log of system messages, including stack traces when the device throws an error and messages that you have written from your app with the Log class.

To run logcat through the adb shell, the general usage is:

[adb] logcat [<option>] ... [<filter-spec>] ...

For logcat online help, start a device and then execute:

adb logcat --help
