[Android SDK] Error updating purchases. ErrorCode: 6

Hey @MarcinScana!

This is kind of a weird error, and even Google isn’t very specific about what it actually means. It seems to be some kind of generic error that can be triggered by multiple issues- there have been reports of this error indicating:

1. A timeout when interacting with BillingClient [link] (maybe an old device with a resource-intensive app)
2. An error due to sideloading apps instead of installing directly from Google Play [link]

Do you have any logs or device information about the users encountering the error?

Hey @cody we have managed to collect logs from the SDK, but unfortunately they do not tell us much - maybe your team could find anything interesting there?

Some logcat logs that we have collected - not sure if this helps with anything:

Hey @MarcinScana,

Thanks for sending those logs over! I was able to take a look on our end and see that the error is happening before anything is sent to RevenueCat, so I’m not able to see a specific error on my end. It seems like timeouts might be causing it since it’s never reaching us.

The logcat errors are interesting - is that error happening when you are testing? There also isn’t a whole lot of documentation about those types of error messages, and I haven’t actually seen that before. I did find this blog post referencing it though: https://medium.com/swlh/some-things-we-learned-while-implementing-in-app-purchase-in-android-9e70c22addf0

After some hours of searching why we got this error, turns out you need to add the email you are signed in on the Google Play app from your phone to the licensed testers list. And you can do that in the Google Play Console. On the page with all apps you can find Settings ->License Testing. Here you add the email address, press Enter, and save your changes.

Could you try that and see if it resolves the error in your own testing?
