Question

I observed that when i use Logcat with Eclipse with ADT for Android, I get messages from many other applications as well. Is there a way to filter this and show only messages from my own application only.

Answer 1

Package names are guaranteed to be unique so you can use the Log function with the tag as your package name and then filter by package name:

NOTE: As of Build Tools 21.0.3 this will no longer work as TAGS are restricted to 23 characters or less.

Log.<log level>("<your package name>", "message");

adb -d logcat <your package name>:<log level> *:S

-d denotes an actual device and -e denotes an emulator. If there’s more than 1 emulator running you can use -s emulator-<emulator number> (eg, -s emulator-5558)

Example: adb -d logcat com.example.example:I *:S

Or if you are using System.out.print to send messages to the log you can use adb -d logcat System.out:I *:S to show only calls to System.out.

You can find all the log levels and more info here: https://developer.android.com/studio/command-line/logcat.html

EDIT: Looks like I jumped the gun a little and just realized you were asking about logcat in Eclipse. What I posted above is for using logcat through adb from the command line. I’m not sure if the same filters transfer over into Eclipse.
