[Solved] Unity In-App Purchasing ClassNotFoundException Android.

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

 

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.

 

Can you describe it more detailed. Which file is not added to the android project.

 

you can read this answer.

Yes, that answer should fix your exported android project.
