Build Signed APK failed - Can't find common super class of [android/content/Context]

Question

This is Android Project. Using Normal Build was successfull, but using signed Key i got this error :

Execution failed for task ':transformClassesAndResourcesWithProguardForFlavorRelease'.
> java.io.IOException: java.lang.IllegalArgumentException: Can't find common super class of [android/content/Context] (with 2 known super classes) and [com/onesignal/ADMMessageHandler] (with 1 known super classes)

Any Idea ? Thanks in advance...

I think Proguard causes this problem.

Add this line to your Proguard file.

-keep class com.onesignal.** { *; }
