How can I find the android log file?

I am using the 开发者_StackOverflowcommand

Log.i(TAG, "Received a message");

But I am not able to find where it is outputted.

Can any body help me about this?

You can view it in eclipse in the debug environment, and you can use adb: http://developer.android.com/guide/developing/tools/adb.html#logcat

You can also download something like aLogCat on a device for looking at live logfile information.

You can also use the adb logcat command from the console (if adb is in your path).
