I had the same fear as you, initially. It's true that there are a lot of possible devices, versions, screen sizes etc. But in all reality, you mostly need to care about 2-3 devices.
- OS: Android 2.2/2.3 and 4.x. (Rest doesn't matter, honestly)
- Device sizes: a big/new samsung galaxy-sized one (~ 1200x700), one 320x480 and maybe a smaller one.
Depends a bit on your target demography.
This isn't actually too much worse than what you have with iOS these days, where you have retina + non-retina + tall device. (possibly + iPad). And possibly 3 iOS versions to think about - 4.3, 5.1 and 6.0.
