Automatic thread

Nice piece of code from Android e-mail client

public static AsyncTask runAsync(final Runnable r) 
{  return new AsyncTask() {
       @Override 
       protected Void doInBackground(Void... params) {
            r.run();
            return null;
       }}.execute();
    }
    runAsync(new Runnable() {
      @Override
      public void run() {}}
    );
