I’m trying to integrate IAP following the tutorial:
https://unity3d.com/pt/learn/tutorials/topics/analytics/integrating-unity-iap-your-game-beta

Running the editor works correctly.

When I export to the eclipse, I have the following error:

Obs:
The APK has been published as BETA in GooglePlay
Google Play Games and Admob plugins are working perfectly!
My Unity version is: 5.3.2.f1

What do I need to run the IAP?

I am investigating this, it appears to be a configuration problem with the Android project Unity generates.

Same issue:
Didn’t find class “com.unity.purchasing.googleplay.GooglePlayPurchasing” on path: DexPathList[[zip file "/data/app/ "],nativeLibraryDirectories=[/data/app/ , /data/app/ /base.apk!/lib/x86, /vendor/lib, /system/lib]]
at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:56)

Version: 5.3.4f

Please try using the Unity 5.4 beta where this issue should be fixed.

Resurrecting. Getting the same issue on 5.4b11

6

Bump. Issue persists on b14

My mistake, the fix has not yet landed into the beta. To workaround this you can manually add Unity IAP’s Android Archives to your project - specifically the JAR files within each.

Yes, that answer should fix your exported android project.
