Boring answer maybe, but Google it. Every specific problem you have try to formulate it in a concise way and google. Usually one of the top answers is from stackoverflow which is totally invaluable as a developer. Make sure you check the top 2 answers most of the time, as sometimes the accepted answer (which is always at the top) is worse than the 2nd answer (which in that case usually has way more upvotes).

If you're new to Android it might be a good idea to try a couple of different tutorials where you create a simple app.
