I think you need to seriously reconsider your business model. If you're trying to earn revenue thru 1-time app sales, then I'm afraid you're in a losing game if you're content with building just 1 app. When it comes to to-do lists, no matter how great it is, the market is flooded with those, and a lot of them are cheap.

"Google is the guy driving this bus" <-- yes, it is, it's sorta like owning a website who's only source of visitors is SEO. It's just waiting and hoping Google doesn't mess up in anyway. When you're so reliant on 1 company for your revenue, something's wrong. You shouldn't put all your eggs in 1 basket.

Maybe it's time to branch out. Explore other money making opportunities.. Maybe, just maybe building a very very good app isn't enough to build a sustainable business. Yes, it makes you proud as a developer to build an app. But we're talking about building a business.

There won't be a lack of developers developing for Android, trust me... when the audience is so huge, it doesn't matter how much friction there is. Huge companies will pay ppl tons of money to deal with the BS. They're 10+ abstraction levels away from the bullshit. They'll just tell the developer team: DEAL with it, develop this in 1 month or you're all FIRED.
