How can I blur and darken the image that will be used as the activity background?

Question

As in the title: I want to blur and darken the downloaded image.
BlurMaskFilter in the SDK sounds relevant, but I can not find any documentation on it.

Any suggestions?

I used this time only once and just for fun (not an expert). Try something like:

 paint.setMaskFilter(new BlurMaskFilter(20, Blur.OUTER));
