PixStack Photo Editor is now available for Android. It features a number of effects, such as grayscale, sepia, selective color, and blur, among others.
Both free and paid versions of the app are available. Functionality wise, they're identical, but the paid version doesn't contain ads. Grab it on the Google Play Store. If you don't have access to the store, you can also download the free version from the app page.
