You’re mostly right. Newer devices won’t share their entire app list by default, at compile time you need to enumerate every app you want to query for, or add what are essentially a list of intent filters (which are like “I want to talk to apps that take this kind of message and payload”). There is still a permission that lets you list all apps like you were able to on pre API 30 devices, but Google makes it pretty difficult to get onto the app store in that state.

You can still send intents as much as you like though (as long as you know the recipient), since they’re the basis for all inter-process communication.

My point is more that an app developer can’t and doesn’t need to use the play store to get the list of apps you have on your phone. This requirement to have the play store almost certainly isn’t malicious and I disagree with the notion that apps shouldn’t be able to use what is essentially system infrastructure to improve their apps. That said, given this is an app targeting the fediverse, it would have been nice for the developer to have made a universal APK build that didn’t require the Play Store.

If this error message is actually talking about Google Play, not Google Play Services, I would bet that it is because it employs Dynamic Feature Modules; something which can only be delivered over the Play Store infrastructure. They’re pretty common in modern Android development since they can substantially improve the user experience for users with Google Play enabled (which is most of them).

Also, I am aware this is being pedantic, but Android just straight up already has an API to get every installed app on your device and interact with it, even on a de-googled phone.

Do you have a data feed to pull from, or some kind of list of matches? It shouldn’t be too hard to use a simple python script to parse a file and post automatically on a schedule. I maintain a repo that doesn’t exactly match your use case, but I could maybe add your functionality depending on complexity

Likewise, an open source project can totally die if they refuse to engage with the needs of the users. The lack of moderation and content management tools have been a longstanding criticism of Lemmy, and instances will migrate to alternatives that address these concerns. It is a genuine legal liability for instance operators if they are unable to sufficiently delete CSAM/illegal content or comply with EU regulations.
