It's taken a while, but Baldur's Gate: Enhanced Edition is now available on Android devices. It costs $9.99 (with some DLC that costs extra), and can run on any Android 4.0 or later.
Baldur's Gate EE originally came out more than a year ago, and was available for iPad shortly after. Even its sequel came out before the original hit Android. But you can download it from Google Play now, at least. It received generally positive reviews.
