In app billing in Android?

Question

Android

I ran into a problem that version 2 of the billing API does not work on a phone with Android 2.3.3. It turned out that Google Market (the old version of Google Play) does not support this. The question is, should I write version 1 support for such phones in the application, or are there very few of them and the costs are not worth it? Is the second version backwards compatible? If you need to write, then tell me the library or a link to the manual where it says how to make a multi-version version of purchases. Has anyone used AndroidBillingLibrary?

Answer 1

According to statistics , 50% of phones are now on Android 2.3.x, so it definitely needs to be supported.
I recommend using some library, because. In-App Purchasing is described rather poorly in the Google docs. I worked with the Android Billing Library , in principle - not bad, although the design of the library itself is not very good, so I decided to finalize it in my repository (see billing)
