Logging on Android phones

Question

call it crazy, but I never use debugging, just logging when developing software for mobile phones... So when coming from Symbian to Android platform I was looking for something similar here. After searching for a while I figured out a way of using logs (I need live logs during the devlopment and file with logs, when testers are using the application), and I would like to ask the audience to comment and might be make an interesting suggestions:

I am using the Log class (http://developer.android.com/reference/android/util/Log.html)
I am using the adb logcat to see the live output from emulator or USB connected device
Since I am developing on Windows I am using the GNU grep port to filter data out from adb logcat, which do not belong to my application (http://gnuwin32.sourceforge.net/packages/grep.htm)
If I need logs from testers I ask them to use the Log collector application to send logs over Bluetooth to the PC (http://code.google.com/p/android-log-collector/)

I welcome any comments to my approach...

There is no need to use grep as logcat supports filtering. http://developer.android.com/guide/developing/tools/adb.htmladb ( IE: logcat MyApp:D ) — stealthcopter, Mar 04 '11 at 08:49

As suggested in the comments you need not use grep , logcat supports filtering.

I have never used the log-collector but what I prefer is to write all logs to the SD card and also have an UncaughtExceptionHandler which logs to separate files . Only a few lines of code are required and it can entirely be controlled by a configuration parameter.

One way could be, you can add java.util.logger in your code. Instead of Log.v, use java.util.logger functionality. This is a powerful logger, which can help you publish the log on to a log file on the sdcard and logcat, both at the same time. You can check this link:-
