Answer by AndroidGecko for How to remove all debug logging calls before building the release version of an Android app?

I highly suggest using Timber from Jake Wharton

https://github.com/JakeWharton/timber

it solves your issue with enabling/disabling plus adds tag class automagically

just

public class MyApp extends Application {

  public void onCreate() {
    super.onCreate();
    //Timber
    if (BuildConfig.DEBUG) {
      Timber.plant(new DebugTree());
    }
    ...

logs will only be used in your debug ver, and then use

Timber.d("lol");

or

Timber.i("lol says %s","lol");

to print

"Your class / msg" without specyfing the tag
