logging - How do I write outputs to the Log in Android?

Question

I want to write some debugging output to the log to review it with logcat.

If I write something to System.out this is already displayed in logcat.

What is the clean way to write to the log and add levels and tags to my output?

Answer 1

Look into android.util.Log. It lets you write to the log with various log levels, and you can specify different tags to group the output. For example

Log.w("myApp", "no network");

will output a warning with the tag myApp and the message no network.
