Android Development: Combining small tiles/bitmaps into one bitmap

Question

Im trying to get all my small images like grass, water and asphalt and so on, into one bitmap.

I have an Array that goes like this:

public int Array[]={3

If all the tiles are the same size you can create one large Bitmap and draw all the tiles in the right location. For example:

private static final int MAP_WIDTH = 10; // in tiles
private static final int MAP_HEIGHT = 10;
private static final int TILE_WIDTH = 10;
private static final int TILE_HEIGHT = 10;

public Bitmap createMap() {
    Bitmap mainBitmap = Bitmap.createBitmap(TILE_WIDTH * MAP_WIDTH, TILE_HEIGHT * MAP_HEIGHT,
            Bitmap.Config.ARGB_8888);
    Canvas mainCanvas = new Canvas(mainBitmap);
    Paint tilePaint = new Paint();
    for (int i = 0; i < map.length; i++) {
        // Grab tile image (however you want - don't need to follow this)
        Bitmap tile = BitmapFactory.decodeResource(getResources(), getResources()
                .getIdentifier(String.valueOf(map[i]), "drawable", "your.package"));

        // Draw tile to correct location
        mainCanvas.drawBitmap(tile, (i % MAP_WIDTH) * TILE_WIDTH,
                (i / MAP_WIDTH) * TILE_HEIGHT, tilePaint);
    }
    return mainBitmap;
}
