I have tried every possible solution have check github, intelxdk forum. & even our forum ..........
and I must say there is no solution for compiling using the default google play & inapp plugin from construct 2 ..........
Well using cranberrygame plugin isn't that easy as everyone is saying ......... Finally I got it working to get the inapp purchase work but when I click on the button to purchase it throws me our of the app with the pop box to purchase .........
And I am not getting the point as how to make it work ????
