Can I silence some logs from classes other than my application classes in android?

Question

When I start my application I have Logcat output like this:

Some of these logs come out from Retrofit, some from drawing, some from Android emulator drivers i guess. All of them appear like owned by my.application.package.

Can I silence of filter out them (or most of them) quickly to get only logs from my project classes without typing all relevant classes in logcat filter?

Only idea that I have at this moment to "mark" my classes with some TAG prefix, but maybe there is better solution?

TAG prefix is not such a bad idea. work manager library does exactly that. They use `WM-` prefix, followed by a lots of tags (class names in their case). — Shlomi Katriel, Oct 18 '22 at 16:09

For now I put something like this in my all classes:

private val TAG = "Cl-" + this.javaClass.simpleName

Previously I had this:

private val TAG = this.javaClass.simpleName
