I want to replace Google Play Services already on my SSG. Just wondering if there’s an app that will push all the notifications…
You need to run your own push services provider like ntfy or gotify and tie all your notifications into it
Look into /e/OS , lineage, and graphene. On the /e/os page, there is a big explanation also on grapahenes documentation page. That helped me a lot.
F-Droid and Aurora exist, i use them on my pixel 3a xl running ubuntu touch/waydroid.
These are app stores, not app services, like GApps, GPS or MicroG
Its one or the other. Either Google Play Services will push notifications, or the apps have to have the ability to handle push notifications on their own (which isn’t common).
Google Play Services can be sandboxed in GrapheneOS, but there isn’t an open source Google Play Services since its not included in AOSP. It is very much a proprietary blob.
An app? Nope. For notifications, there is open source alternatives to Google and Apple services but it is used in the apps side, not users side. Have a look on microG and Open GApps to flash in your Android device; it might help you.
F-droid?
Free and open source. Allows you to install and automatically update apps from various app stores.
