You can try something like the following:
Bitmap grayscaleBitmap = Bitmap.createBitmap(
colorBitmap.getWidth(), colorBitmap.getHeight(),
Bitmap.Config.RGB_565);
Canvas c = new Canvas(grayscaleBitmap);
Paint p = new Paint();
ColorMatrix cm = new ColorMatrix();
cm.setSaturation(0);
ColorMatrixColorFilter cmcf = new ColorMatrixColorFilter(cm);
p.setColorFilter(cmcf);
c.drawBitmap(colorBitmap, 0, 0, p);
