If you are comfortable working in C++ you can probably pick up pretty easily anything else. I think there is a limited amount of work to be done remotely in C++ since most of the postings seem to be for more "hipster" technologies. There a decent amount of Android work to be done though.

As for the maze, I think it's something we have to come to terms to. There is just simply too much. While you can be a generalist or specialize in one thing we have to accept that there is still too many technologies and we can't know everything. The good news is that you get to pick whatever you want!
