I'll go against the majority advice here. Don't start downloading large collections of digital stuff, whether pdf's, videos, wikipedia or whatever. For one thing there might be electricity outages too. And you can never really be "complete" and self-sufficient with educational resources unless you have a very clear idea what you will focus on. Make the best of a bad situation by going deep into only one important and difficult and relevant for your future career subject. Pick one good and complete resource. E.g. a well regarded book with plenty of coding exercises, or a well documented open source project, complete with documentation etc. Then go over it line-by-line, understand and replicate everything, make it your own. This approach will minimize that you will need random other resources. Hopefully at the other end of it you'll have a new and powerful tool in your toolkit. What is the best project to focus-on? you know better. Something orthogonal to android app development would be one direction. Maybe learn python and a backend framework like django that has excellent documentation. But taking android to the next level makes sense too. You know where you want to be. Lets hope that at some point we'll learn how to live in peace and stop wasting human life and talent.
