Replace QtPurchasing with Java code using Billing Library v3.

Looks like QtPurchasing uses some deprecated billing API and it probably no longer supported. See [login to view URL] for more information. Need an Android developer who will implement QtPurchasing functionality in Java with C++ interface for using from a QT app. You send me the code, I test it on various android versions and then pay. An experience with QT+JNI is a plus.
