I want to export my project as a unsigned apk but it said "build failed" and I am seeing too many lettering about error. But I deleted Mobile IAP plugin and I am trying, then it is working and build successful. I did not install my apk for google play store yet, so mobile iap plugin has no function yet. However, it will work in certain future processes. (during purchases). But I am having this problem, what is the problem? What should I do to prevent this?
NOT: The IAP plugin has not yet been configured. (I did not set Mobile IAP's settings, So I did not enter "public key" and like that")
