In-app testing. "You need to sign in google play account."

So, while Kwon Sang Ki solves the iOS problems with his cranberry IAP plugin, I decided to publish under the android.

And...i have faced other problem <img src="{SMILIES_PATH}/icon_e_smile.gif" alt=":)" title="Smile">

During the test purchases on my phone, I get the message:

"Authentication requied. You need to sign in google play account."

I have test mail in license test section of developer console, and entered Google Play with this mail.

I tried to delete and create again accounts in my phone. I even reseted completely phone settings. Nothing helps.

Tried recommendations from here: http://stackoverflow.com/questions/1862 ... -app-billi

and here: http://android.stackexchange.com/questi ... play-store

No effect. Again, I do not know what to do.

Ok, I had to publish an alpha version. This error is gone, but another one appeared.

Now "Purchase Product" says that this product is not for sale.

APK version is the same in Google Play Console and device.

Request Store Listening works ok, ProductInfo too.

My problem mentioned here )

Generally, way of installing apk through "adb -d install" not working in my case, but alpha testing (with app link sent to testers account) works fine!
