If somewhere in any third party lib you will see something like this:

   final public class AnyClass {        
        private static final Logger logger = Logger.getLogger(AnyClass.class.getName());
         ...
            if (logger.isLoggable(Level.FINE)) {
                logger.fine("any log event");
            }
         ...
     }

Add to your code this after creating first instance of AnyClass.class:

SetupLogger.setup(Arrays.asList(
                new Pair<>(AnyClass.class.getName(), Level.FINEST),//AnyClass.class.getName() is because instance `logger` has his name
                new Pair<>(AnyOther.class.getName(), Level.FINEST)
        ));

SetupLogger .class

public class SetupLogger {

    static public void setup(List> loggerNames) {
        // suppress the logging output to the console
        AndroidLoggingHandler rootHandler = new AndroidLoggingHandler();
        AndroidLoggingHandler.reset(rootHandler );
        for (Pair pair : loggerNames) {
            Logger logger = Logger.getLogger(pair.first);
            logger.setLevel(pair.second);
        }
    }
}
