Question

I am using facebook-unity-sdk-7.3.0 and GooglePlayGamesPlugin-0.9.32 in my project. it does not let me build for android and fails with error \'Unable to convert classes

Answer 1

Maybe it's too late to answer, I was facing the same issue, I created a plugin this plugin contains Facebook SDK+Admob+unityads +unity IAP, all of them work together, I've created this plugin in unity 5.6.0, but I've checked it, it is working fine in unity 2017 as well, there is a scene "DemoScene", just open it everything is implemented, unity ads, admob, facebook share with callback, unityIAP.

Note: before importing the plugin kindly delete all the old plugins, also go to services and turn on unity ads. http://www.mediafire.com/file/ccvj7ixir8ive25/FB_ADMOB_UnityIAP_UnityAds_Plugin_Hameed_Ullah_jan.unitypackage
