Android error while retrieving information from server 'RPC:s-5:AEC-0' in Google Play?

Question

I have been getting the following error on a mid-Android device.

Error retrieving information from server rpc:s-5:aec-0` .

It pops up when I try to download my in-app purchase product from the Play store.

I did coding from the tutorial Simple InApp Billing / Payment and updated my APK file in Google Play, but it not published. Is it compulsory to publish an app on Google Play?

I installed the same APK file in a device which I have kept in Google Play. Now I am getting this error. What is the problem and how do I to solve it?

Answer 1

To fix this issue you need to remove your Google account, then add it again. To do this follow these instructions:

(Or just find the account under Settings > Personal > Accounts and Sync > Click the Google Account > Click Menu button > Click Remove Account > Confirm deletion.)

Answer 2

I've been having this problem too and I'm not sure why. Some people suggest removing your Google account and re-adding it and/or deleting the Play Store cache. I'm looking for more solutions, but it happens for all apps free, paid, whatever.
