I think this is probably a valid thing to consider in most APIs, especially if they're statically linked APIs, where you can actually check. The documentation should also specify the conditions under which this should happen, to be fair. I think the problem here is something that should be clarified in the documentation, I'd assume since it's not you should follow the safe practice of checking values or letting them crash and get reports after testing on your end with a test suite. But again, this is much more to do with the dynamically linked nature of the Android framework, as opposed to a static library (where you usually *can* check what the case is).
