Hi,
why do you want to learn Android app programming? Just for fun, or to program a project, or for job application?
Are you familiar with Java basics? OOP, Getters and Setters etc.?
I would suggest to start with simple tasks and progress to little projects.
Do you speak German?
At the moment I am a freelancer and programming an app I want to put in the playstore before christmas.
I am patient for sure ;-)
Greetings,
Richard, Mannheim
