We've seen collections of Android development resources in the past - this list, and if that's not big enough, this BIG list - but from Vladislav Bauer comes the biggest list yet: Android Arsenal. This one is thorough, with a huge collection of tools and resources divided up into categories, such as:
- Action Bars
- Automation Testing
- Social Networking
And quite a few more. In total, there are 55 categories, each with a handful of links to get you where you're going. If you need some tools to help you with anything, really - I mean, 55 categories, come on - take a look at Bauer's Android Arsenal and see what you can find.
