CountUpTimer for android

Usage:

new CountUpTimer(1000L) {
    @Override
    public void onTick(long millisElapsed) {
        Date date = new Date(millisElapsed);
        DateFormat dateFormat = new SimpleDateFormat(TimeUnit.MILLISECONDS.toHours(millisElapsed) >= 1 ? "HH:mm:ss" : "mm:ss");
        Log.i(dateFormat.format(date));
    }
};

android.util.Log without the tag

Perhaps having come languages like PHP, Javascript or ActionScript, I just can not get used to tagging log output.
Hence I came up with a class: OneLog – one tag.

I initialise OneLog.TAG in my Application class, but it really can go anywhere appropriate.

public class MyApp extends Application
{
    public static final String PACKAGE;
    static {
        PACKAGE = MyApp.class.getPackage().getName();
        OneLog.TAG = PACKAGE;
    }
    ...
}

And then you’re free (from tagging):

Log.i("test log");

AndroidAsync socket server service example

AndroidAsync (https://github.com/koush/AndroidAsync) is an asynchronous socket, http (client+server), websocket, and socket.io library for android. Based on nio, not threads.
Here is an example how to create a working socket server service within seconds, without having to think about threads.
