$30-250 USD

In Progress
Posted over 7 years ago

$30-250 USD

Paid on delivery
I have an existing health & fitness Android app that is working well for most users. Recently, the InApp purchase feature stopped working on more modern versions of Android, likely because the app is using an older billing library or because it wasn't used properly. This project is to access the existing code base, identify the problem and fix the issue. The project is built with Java and comes with an Android Studio project. Source code access will be given after signing NDA. The attached screenshot shows the given error message.
