I wrote this class in order to not having to write tag every time (because of code duplication and risk of typos).public class TaggedLogger {    public static final TaggedLogger GLOBAL = new TaggedLogger(Global);    private final String tag;    public static TaggedLogger forClass(Class<?> someClass) {        return new TaggedLogger(someClass.getName());    }    public TaggedLogger(String tag) {        this.tag = tag;    }    public void debug(String message) {        Log.d(tag, message);    }    public void info(String message) {        Log.i(tag, message);    }    public void exception(String message) {        Log.e(tag, message);    }    public void exception(String message, Throwable exception) {        Log.e(tag, message, exception);    }    // skipped}Using:public class MainActivity extends Activity {    private static final TaggedLogger LOGGER = TaggedLogger.forClass(MainActivity.class);    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        LOGGER.debug(Initialization: start);        init(savedInstanceState);    }    // skipped}What do you think? Maybe this class is useless?Help me choose a more appropriate name for this class (if TaggedLogger isn't good) ?

I do not consider your class useless, I have actually done a similar thing myself. Very similar actually. Perhaps even exactly the same, pretty much.Overall, your code is very well-written. You use final and private where you can, which I like.A few comments:private static final TaggedLogger LOGGER = TaggedLogger.forClass(MainActivity.class);Even though it is correct that constants are written in ALL_CAPS. One exception for this is loggers. If you write LOGGER.info and stuff often, that LOGGER will pick on your eyes after a while. I would recommend using the name logger (lowercase) instead.public static final TaggedLogger GLOBAL = new TaggedLogger(Global);I am not sure if you really need this one. Especially not inside that class.It is good that you have not made your class a singleton at least, but I'm not sure if this public static 'global' is really necessary.I can recommend using log4j for Android for logging. Log4j is a very nice and popular logging framework for Java, and it is possible to get it working on Android.
