Other Few question about posting app in play store

[incendio]

Hi guys,

I want to post my app in Google Play Store. This app is a paid app based on subscription fee.

Can Play Store handle this type of payment ?
If it can, how & what should I set in my app?

My app contains old library that is currently not develop anymore. For now it still can run on SDK 30, but don't know in the future.
I would love to use new library that has the same functions as old library, but till now, there are still not substitute for this old library.

Since Google has policy to enforce app to use newer SDK, is it possible to post on play store app that contains newest SDK but it is not a complete app. This app on Play Store only serve as a front end, when user run it, it will download latest & complete app from my server then install it on user phone. After this installation, the next update (if any) will download directly from my server and not using Play Store anymore.

Is this possible? Is it against Google Policy?

Thanks in advance.

You need to use the in app purchases feature for this.

I guess that you mean targetSdkVersion = 30 + Android version = 30. This will be required next year.

As far as I remember it is against Google policy. Not 100% sure.
