> This was always using Google's proprietary data, even in the G1 days. They split it out into Play Services, so Chinese phones using another provider would be possible. Incorrect, in the past your apps could access the raw data and feed it into Mozilla’s Geolocation APIs. This is not possible anymore (but returning in limited form with 9.0). > Background notifications weren't even possible on the G1 when it launched. When background notifications were first made available, they used a Google service and were never part of AOSP for that reason. Chinese phones use other push services inside the firewall. Incorrect. Until Android 7.0, apps could run in background and open their own sockets for background notifications. > None of those existed on the G1 and are simply sensor fusion implementations on the open sensor APIs. Incorrect – the open sensor APIs are only available for foreground apps. You can not collect any stepcounter data unless your app is constantly showing a notification in foreground, or is using the Google Fit APIs. > Yes, you can. https://developer.android.com/guide/topics/graphics/opengl https://developer.android.com/guide/topics/graphics/opengl Not on any devices, you’ll need to load bindings through Google Play Services. > You need to understand the difference between the platform and the services that Google provides on top of it. I seriously suggest you actually go and try to build apps for non-Google Play devices at least a single fricken time, or try to build ROMs, before you comment. You’re just making a fool out of yourself.
