Logcat debug level --help

[Yash Jain]

Hello All,
I have one dumb question,
when i read a logcat message through command logcat -d, i will get a list of all events with the prefix I, V, D, W, and E which represent Information, Verbose, Debug, Warning and Error.
I am interested only to display the error messages in the log file( logcat -f log_error.txt) or to the console( logcat -d).
Can anyone help me to print only the error log messages.

Thanks in advance.

Regards,
Yash Jain.

There is DDMS tool which is part of Android SDK, which allows creating
the Filter for logcat messages using the Error Log level.
The procedure is straight forward...
1. Start the DDMS
2. Once it is launched, one can see the "+" sign in Green color, to
add the Filter.
3. After clicking the "+" sign, a small window will pop up, named Log
Filter,
4. Just specify any user-chosen name for filter, and then Select the
Option, by Log Level.
5. Choose the appropriate log level such as Error, Warning.

Hope this helps...

Hello Yash :)

You can pass logcat a filter specifying which level of event to show, in the form tag:priority, where the priority is given as the single letter prefix you have mentioned. Sounds like you don't want to specify a tag, so you can just use * (all tags). For example, to show only error messages:

$ logcat *:E

There's some documentation on filters for logcat at http://developer.android.com/guide/developing/debugging/debugging-log.html#filteringOutput
