Framework/Library for Android App

If it comes to game, we all merge our voices and scream “LIBGDX FOR GOD’S SAKE!” together. How about normal app? Anyone know a good framework to speed up development?

I come to this because I see many apps have beauty interface which I believe not coming from google’s design. Even almost most twitter clients like Plume, Tweetcaster, Twigee, etc share same layout. My google-fu came up with ignition and droid-fu, but I want to know more.

EDIT: to save threads, if anyone know good tutorial on android game dev withOUT any lib (pure, using built in canvas like java2d on desktop) please share it too. Don’t worry I wont use it.

So basically you want to learn raw Android? Try Google’s tutorials :stuck_out_tongue:

For game, yes. But not for common app.

EDIT:
For common app, I found another one called Open Mobile IS. But it looks like unmaintained. There’re lot of frameworks to speed up android dev (and even cross to iOS and WP too!) but they’re all web app which use Js and HTML5 :emo:
