I am wanting to learn app development but don't have an idea of what to create. I love the Android TV platform and would love to make an app that helps the experience but have no ideas. Any suggestions for something you have been looking for but can't find?
As a professional developer (director now, but w/e), learn by solving a problem that has already been solved - most unsolved problems are that way because it takes a lot of work for an experienced dev (or team of them). Once you're into Android TV it's launchers, games, or something cloud based with an app on the frontend. These are all complex tasks, with game development probably being the least so (or most, depending on where you take it and what engine you use).
If you try to bite off more than you can chew on the first pass, that will be just as discouraging as trying to make a hyper-realistic colored pencil drawing without first developing even basic drawing skills. Make something simple like a calculator, to do list, etc. Turn the to do list into a simple project management app. If that sounds boring (it kind of is), look at the problems being solved with spreadsheets and try to solve them with an application. As an example, I'm currently writing something to help my wife manage her model horse collection. Once you get into UI, data models, database, image uploads, tests, etc. it can get fairly complicated for something that seems trivial, and you get to learn a lot along the way. Even better if you can find someone to help you on your journey, because self-taught is a strength and a weakness, and that weakness is overcome with the input of experienced developers.
