<pre>Im using WallpaperService to set the live wallpaper on homescreen. Im able to set 10 pics from resources and rotate them

class WallpaperEngine extends Engine {
    //frequency selected by user to update the wallpaper
    private final int Wallpaper_DURATION = utils.getFrequency;

    private int[] mImagesArray;
    private int mImagesArrayIndex = 0;
    private Thread mDrawWallpaper;

    public WallpaperEngine() {
        customWallpaperHelper = new CustomWallpaperHelper(getApplicationContext(), getResources());
        mImagesArray = new int[] {R.drawable.one,R.drawable.two,R.drawable.three,R.drawable.four,R.drawable.five};

        mDrawWallpaper = new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    while (true) {
                        drawFrame();
                        incrementCounter();
                        Thread.sleep(Wallpaper_DURATION);
                    }
                } catch (Exception e) {
                    //
                }
            }
        });

        mDrawWallpaper.start();
    }

    private void incrementCounter() {
        mImagesArrayIndex++;

        if (mImagesArrayIndex >= mImagesArray.length) {
            mImagesArrayIndex = 0;
        }
    }

    private void drawFrame() {
        final SurfaceHolder holder = getSurfaceHolder();

        Canvas canvas = null;

        try {
            canvas = holder.lockCanvas();

            if (canvas != null) {
                drawImage(canvas);
            }
        } finally {
            if (canvas != null) {
                holder.unlockCanvasAndPost(canvas);
            }
        }
    }

    private void drawImage(Canvas canvas)
    {

        Bitmap image = BitmapFactory.decodeResource(getResources(),
                mImagesArray[mImagesArrayIndex]);
        Bitmap b=Bitmap.createScaledBitmap(image, canvas.getWidth(), canvas.getHeight(), true);
        canvas.drawBitmap(b, 0,0, null);
    }
