Can we add Debug information to Logcat using ADB commands or any other means?

I am running a script on an Android device and getting data from logcat. Is there anyway I can add debug statements to logcat in runtime using adb commands or any other means?

Solution

  • By default Android should redirect stdout and stderr to /dev/null. You can for instance change this behaviour by redirect stdout/stderr to log with:

    $ adb shell stop
$ adb shell setprop log.redirect-stdio true
$ adb shell start

    Update: From within your script, just use:

    log -p i "your message"

    to append the message to the log
