Using Android Logcat to display like this

I am new to Android and I am currently trying to understand how to use the logcat well. If you look at this here:

LinkedIn scribe OAuth library unable to allow access to LinkedIn account

This person has logcat print out all system.out.println() to verify that the code works without having to write a full app to run. I was hoping someone could show me how I might be able to do this. Thanks

I'm not sure what you mean by this:

without having to write a full app to run.

But the code in that question most probably does not generate those statements without actually running them as an APK.

And then it is just a fact that a line like this:

System.out.println("=== LinkedIn's OAuth Workflow ===");

Wil behave as if Log.? is called. So the way you can do what happens in that question is just put your log-lines (either trough Log.? or if you please with System.out.println) in your APK. But you need to run it to .. well.. run it :)
