Answer 2

AIDE (Android IDE) is an android app, allowing you to write android-apps on your android phone.
of has some examples also.
you can directly compile and run on your phone.
although it is not really a course, it allows me to make some small apps anytime, anywhere.
Of course I also used google to gain examples, but the trial and error also taught me a lot.

there is a free basic version, and a paid professional.
