How hard is Android development?

So I've been getting really interested in learning how to code and program. So far I've been following a series by mybringback on YouTube that teaches java. Once I finish that series, I plan to follow the tutorials on the android developer site. Do you guys think these classes and tutorials will be enough? I'm understanding java pretty well so far, so hopefully android development won't be too my harder. I've also read somewhere that you only need to know the basics of java to develop for android. So if you are a developer, how hard is it to develop for android? Thanks!
