Are there any frameworks out there which make it even more easy than it is to build Android applications and would you be interested in one?
There are several frameworks of different scope and purpose to make mobile application development faster, or cross-platform, or code-free.
Technology thrives on competition and new ideas, so please don't take the presence of several other solutions as a deterrent from making your own if you think you can build a rounder wheel.
There's also phonegap, which you can use to write android apps using html+javascript.
I have completed developing an Android Framework for everyone to be able to use easily and quickly. I already developed several applications with that and it is called appFramework and as you can see, you will be using almost every feature and latest libraries in seconds with just extending or implementing the classes i have already created in the library. Setup process is already included, rest of using roadmap is up to you!
Already Created Classes of Features:
Have a nice coding!
One of the best right now IMHO is Appcelerator
Free and open-sourced, develop one app for all major platforms (cross-platform), compiles the app to native code, has a rich API...
I enjoyed playing with it.. very easy to learn :)
Hope this help!
P.S.: even though it sounds like I work there, I don't... unfortunately for me :(
