Google Play Billing V6 show error DF-DFERH-01


Hi I am integrating Google Play Billing Library on my project on a fragment in android studio to sell a subscription, I alrready make the set up in the Google Play Console uploading my app in internal test and making the subscription basic plan, then I continued to make the logic process in my app following the steps in the documentation, everything is fine, I checked the product list and it has the subscription´s information, but when the app tries to show up the google play window it appears the next error message:

I searched in internet and they said to clear the data, cache of the google play store and google play service and restart the phone I did it but it did not work, I open another app with subscription and it shows the window of the google play subscription without problem, so I dont think the problem is the google play store

otherAppSubscription

I have tried a lot of things, download the app from google play store (internal test), changing a fragment for an activity, using the downgrade version of the libray and nothing work, I share you my code, thanks in advance

Solution

  • This error often occurs when incorrect data is passed to the Billing Library.

    In your case, please find the relevant offerToken:

    String offerToken = productDetailsList.get(0).getSubscriptionOfferDetails().get(0).getOfferToken();

    (Of course, this is just an example, and I'm omitting various checks. I'm assuming that the first product is a subscription and that your desired offer is the first in the list returned by getSubscriptionOfferDetails().You should use your custom logic to find the right offer.)

    Afterward, try removing the line .setOfferToken(String.valueOf(productDetailsList.get(0).getSubscriptionOfferDetails())) with setOfferToken(offerToken)
