As a full time Android developer, I can tell you that wouldn't be a burden. First off, there are already lots of places you have to handle compatibility based on the version of the phone, intents available from other apps installed on the phone, or capabilities (even something as basic as a phone can't be guaranteed if you support tablets). Obviously you can turn small things on and off in a block of code with if statements, but you can handle major changes with the Fragment model. If you have a drastically different UI due to a missing intent/permission/API feature you can actually ship the app with 2 different Fragments and decide which one to show at runtime. As an aside, I turned off auto-updating for Facebook and will not upgrade from here. Too many permissions, too intrusive to the UI. I have deleted Facebook from my phone before and I'm fine without it now.
