Well good luck if you do give a go, SRS. If you do, one Internet resource that I think is excellent that you'd probably bump it to is StackExchange. It doesn't aim to be a tutorial but it can answer questions like "how might I say in Java display an integer as a hex string (base 16, eg 255 is FF in hex)" and "why is this failing on Android?"

It's maybe for a bit further down the line than just getting started and writing your first "hello world" program but I find it can save a lot of time. I usually find someone else has already asked my question and at least one other (and there can be more than one good solution) has answered it. I think the inexpert me has only provided one possible solution to a problem but the count of times it has helped me out runs to several hundred.
