Adding in-app purchase to existing published application and testing it without publishing

问题

I'm trying to add in-app purchase for my existing published app that didn't previously have billing permission. I've uploaded an updated APK with billing permission, but didn't activate it since I don't want to publish this draft. However, I can't add in-app product - it still says "the current application version does not use the BILLING permission". Any way to solve/work around this problem?

回答1:

Change Android version code in Androidmanifest.xml file.

android:versionCode="1"

suppose if your Application version code is 1 now change to 2
