iap error android:authentication is required, please sign in

Hello

I built my app via intel xdk. it has the official IAP plugin . Before i used cranbeerygame IAP with the same problem

I uploaded the app to google play to test as Alpha

Published it

used a test account to purchase IAP

I get an error message "Authentication is required. You need to sign into your google account"

This message occurs only for my app i can purchase other apps on the store so its not an google play issue but something with the plugin/ build / configuration

Did you correctly set up your game iap listing on google play?

Yes, actually at some point i was able to make a purchase, but after a couple of updates to my project problem started

it happens in all of my test devices, so its not replated to a device or a testing account

are you using a google account that's not with your dev account? if your using your dev acct it can cause issues

yep

im having the same problem. Did you find any solution?

IAP testing behaves strangely when in beta/alpha. Once it's live it just works. I've spent a week trying to find the problem. There are posts on the internet from developers struggling to make it work, not just C2.

If you get the error, save yourself a time, test just if variables are triggered properly and once the game is live, make one purchase from a friend's device, just to be sure. Look at this, try testing it from a different device and account. There may be a delay with authentication, give it 48h and it might start working.

Just F..k i had lost an entire week on this :I okey ill give it a try and tell thank you Noga !

well , even in production it makes issues. restore deosnt work well

do you know how to restore products ?

on restore success triggers even when i have not purchased the product so i wonder how to check if a managed non consumable product could be restored

it still not working... it keeps showing the "authentication required".....

.... i can't belive that the problem was Google. "Authentication Required" is for the ID of the product, not for the user -_-'' i had wrong ID in the game, when changed, it worked... If i get more info i'll share it.

Found the problem. I guess my device stored purchased information when i used a clean device it worked fine

Did you make the test purchase? Because you said in the previous post

"...on restore success triggers even when i have not purchased the product..."

When making a purchase of managed product, the information is stored on the device and on Google servers. To make a new clean purchase from the device, refund the purchase from your Wallet account and after couple hours you'll be able to make the purchase again.

I Have the same problem. C2 IAP (as test mode) -> Intel XDK Crosswalk build -> upload to Android Dev as Test Alpha release -> set the in app id as the same of the c2 project -> install on my device the xdk arm build.... when i try to buy -> "Authentication is required. You need to sign into your google account".

i'm going crazy... please help me
