Android in app purchase: Signature verification failed

Question

I have tried for several days to solve this problem, using the Dungeons demo code that comes with the SDK. I\'ve tried to Google for an answer but can\'t find one.

Answer 1

The error is caused because of the wrong license key. Maybe the license key is probably from your another app.

The solution is to use the proper license key from :

Play console > App > Development Tools > Licensing & in-app billing
