I was looking for something similar to CocoaControls targetting Android developers for sometime now. I recentrly found the following:
AndroidViews
and The Ultimate Android Library
Also checkout the following:
AndroidKickstartR helps you to quickly create a well configured Android application using the most popular libraries. It creates and configures your project for you.
Android Asset Studio allows you to quickly and easily generate icons and other resources in the appropriate sizes (similar to Iconify for iOS)
Edit: More Mobile Dev resources at AppDevWiki (via alexsapran)
antonis.log() 
Very nice and useful links. I found an interesting site that might help you as it helped me with my mobile projects.
Is a list of mobile development components (for iOS and Android).
