Here are some great tutorials and resources to get you started:
- Udacity – Developing Android Apps: This 8-week online class has a good amount of free elements, taught directly by Google engineers. The course won’t just copy-paste code, but it will help you learn some of the core concepts and features you’ll need.
- Android Developer Training: Part of Google’s documentation includes training tutorials on how to use its tools. These documents will walk you through basic features of the IDE. If you don’t have much experience developing applications, this might not turn you into a master dev, but it will help you learn the tools.
- Vogella: It’s worth mentioning Vogella tutorials in just about every section here. This massive set of tutorials covers just about everything you could cover. If you have a basic question not covered above, check Vogella.
