This would be a great tool to have. One thing to watch out for is version incompatibilities, which are a much bigger problem in Android than other frameworks.

Not only that but also devices fragmentation. Google is doing much to address this, but there's still an ocean of troubles in this field. If a guy would have enough patience and traction to get an "android compatibility framework", he would surely be a hot shot. I'll dig into that maybe :) Or does that exists already? AFAIK not yet. Any input?

http://actionbarsherlock.com/ would be a good piece in Android compatibility framework. I am not aware of anything comprehensive though.

Great. Correct, I almost forgot it. Thanks for the input. I'll dig into that.

Seems to have been tried out before with not enough traction to get relevant. But I believe that now that Android tools and community are getting stronger, it could make sense. Ruby Toolbox is just great. So it's a very good model to base on. imo.

Wouldn't Maven suffice?

Saying that Maven does the trick is like saying that Bundler does what Ruby-Toolbox does which is not the case. The key point here is to be able to recognize quickly which dependency to add given some requirements.

I would love this. Here's to hoping it takes off.
