Google Tasks API from Android - Access Not Configured

Question

I believe this is a common problem. Even this documentation points it out: http://samples.google-api-java-client.googlecode.com/hg/tasks-android-sample/instructions.html

I have created a project for my Android app here: https://cloud.google.com/console/start/api?id=tasks and turned on Tasks API. Inside the project for the Android, I set up SHA1 key and name of my package (:com.gruszczy.eisenhower). The same package name is inside AndroidManifest.xml. And yet, when I try to run my app, I get an error below. Does anyone know, what I am missing or how I could debug this somehow?

Answer 1

I have deleted the project and recreated it several times. At one point it started working. I guess must have been some temporary fluke.
