With Google making it more closed every year, I wonder if is it worth it. I don’t want to learn it to find a job or anything, it’s purely for open source development.
I’ve seen a few devs dropping FOSS apps due to Google decisions. Like the developer of a music player I used (Phocid):
According to him and I agree:
Because Google is essentially killing apps distributed outside of Google Play, I have lost interest in Android development and plan to switch to a different OS once my current five-year-old phone dies.


I think it’s still fine, especially given that non Play Store apps will still be runnable, albeit with a very stupid 24 hour waiting period if no action is taken by relevant regulatory bodies.
But if you are looking to eventually ditch Android for Linux phones, you could always try your hand at making Linux-native mobile apps!
plus, the apps you create can be installed normally without a stupid waiting period on custom ROMs like LineageOS, GrapheneOS, iodeOS, and e/OS!
