Android – failed to deploy to App Engine – you must log in to perform this operation

I am new to Android studio and have just completed this tutorial https://github.com/GoogleCloudPlatform/gradle-appengine-templates/tree/master/GcmEndpoints Not much trouble

However, when I tried to deploy my backend to the application server, it promised me: "you must log in to perofrm for this operation"

I don't know why. I can easily find my projects in the list, and I have logged in to my Google account on various browsers, including chrome

I've been online, but I haven't found any other problems before

Best regards to Alan

resolvent:

Your auth may have been completed not long ago, and the system can no longer see you authenticate correctly, which can explain this behavior

At the bottom of the item list, you should see the "add account" button. Click here and re verify. The bad flag should be cleared:)
