Code example for ThreadPoolExecutor

            new ThreadPoolExecutor.DiscardOldestPolicy());
     * An {@link Executor} that executes tasks one at a time in serial order. 
     * This serialization is global to a particular process. 
    public static final Executor SERIAL_EXECUTOR = AndroidUtils.isHoneycombOrHigher() ? new SerialExecutor()
            : Executors.newSingleThreadExecutor(sThreadFactory);
