  1. Playing sound in andoird

    Adding sound and music to your app is extremely easy. Place your sound file in a new directory res/raw.

    import android.media.MediaPlayer;

    and then where you want the music to play:

    MediaPlayer myMusic = MediaPlayer.create(this, R.raw.splashsound);
    myMusic.start();

    where splashsound is the sound file's name without the extension.

    That's it!

  2. Programmatically adding buttons in Android

    Well I have had a frustrating few hours working out how to add buttons dynamically. Here is how I did it. Firstly, you need to give the layout an ID in the xml file.

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

  4. Look and Feel ToolBar solution.

    This solution is written coz of the problem i have faced for almost a week and after a huge panic, i came to find an alternate solution to solve the problem.
    The problem is Java Synthetica BlackEye Look and Feel with the desktop application. Well, if you try to place a tool bar over your desktop application, you will
    never be able to see LAF(Look and Feel) effect over it. You will most probably get even more confused if you will see the effect on the menu items. Well, what is the actual ...
  5. Fun little optimization

    Disclaimer: While optimizations can be fun and addictive, determine if your particular application needs any before attempting to optimize it.

    I've always wondered if the Java compiler was capable of performing certain loop optimizations. So for fun, I picked a two of them (a simple permutation and loop unrolling) and tested them out.

    public class Test
    {
     
    	public static void main(String[] args)
    	{
    		final int DIM = 0x2000;
