TLDR: I'm currently looking for suggestions on where exactly to get started programming android apps.
I am by no means new to coding nor am I an expert, however I have never done JAVA before. Because of this I am currently reading JAVA for Dummies. Following this I plan to read Android Application Development for Dummies. Thus far I have simply done the Hello Android tutorial and followed the tutorials by CornBoyz on youtube. I still do not feel as though I have a good grasp on the subject matter.
If someone could please provide me with "homeworks", preferably ones that have solutions I can turn to when I get stuck, I would greatly appreciate it. That being said any other, tips or suggestions would be greatly appreciated.
