What is the semantics of the return value of the Android logging functions (e.g. Log.v() )?

Question

The Android logging functions return an int. The documentation does not say anything about them. What does the return value mean?

When I try in my simple app, I get 18 for the following Log.v call:

android.util.Log.v("MyApp", "my message");

Answer 1

It's the number of bytes written, from the underlying println.
