I am trying to do this right now, I want to make android apps but I already have one strike on my account and the threat of losing everything associated with Google is too much. I already successfully moved my email but that took something like a year. Finding all the places where I used that address wasn't easy. I am now wrestling with photos, I haven't found a service that I like yet. I'll try nextcloud but I am not very keen on paying for a vps just for that and all my other have their resources allocated to running other websites. Another VERY important one for me is really Google maps. I travel a lot and both the public transport features and search are extremely useful. And last but not least apps. I don't know if I can make it with just f-droid. For example, neither maps.me or Here WeGo are on it.
