What do you recommend to read for Android developement? The SO documentation is not that great for me since I'm just strarting to create some apps?

What's about the Google documentation? They also have trainings and tutorials. I also want to get into Android development and did the first tutorial there...

developer.android.com is pretty good in my experience. For examples google has enough stuff.

Here's how I got started. I had an app idea, learnt the very basics first. Then started googling "how to do this, that.." and learnt many things on the go. Maybe atleast you'll be motivated to create the app and learn at the same time.
