nope. nope. nope.

are you supposed to write your own firebase? develop your own android? yes, OP learned a hard lesson about Google, but that does not mean that you cannot build stuff using just one provider. you need to do your due diligence of course. You need to have a plan, of course. But the cost of doing this on 2 platforms skyrocket. And especially for a small player the multi-cloud, massive investment is just not an option.
