How to draw a smooth/dithered gradient on a canvas in Android

Question

Several answers mention to use GradientDrawable.setDither(true) to draw smooth gradients in Android. That has no effect in my code. Any idea what I have to change to get a well looking gradient in my live wallpaper?

GradientDrawable gradient = new GradientDrawable(Orientation.TL_BR, colors); gradient.setGradientType(GradientDrawable.RADIAL_GRADIENT); gradient.setGradientRadius(canvas.getWidth() * 2); gradient.setDither(true); gradient.setGradientCenter(-0.1f, -0.1f); gradient.setBounds(cb); gradient.draw(canvas);

Seeing as you have a Canvas to work with. Here is one option.

private Bitmap makeRadGrad() {     RadialGradient gradient = new RadialGradient(200, 200, 200, 0xFFFFFFFF,             0xFF000000, android.graphics.Shader.TileMode.CLAMP);     Paint p = new Paint();     p.setDither(true);     p.setShader(gradient);      Bitmap bitmap = Bitmap.createBitmap(400, 400, Config.ARGB_8888);     Canvas c = new Canvas(bitmap);     c.drawCircle(200, 200, 200, p);      return bitmap; }
