Exception when trying to use Google Calendar API in android

Question

I am getting exception as below:

Well, I've used or say copied same code as this shown in google doc https://developers.google.com/google-apps/calendar/quickstart/android .And I know it is the same error which is already mentioned in troubleshooting part of this doc but as mentioned in its solution, I had checked my SHA1 fingerprint and also package name and all the stuffs but still getting same error. And also I tried to google and followed each and every link the google suggested but nothing works for me so my last option was STACKOVERFLOW and so I am here. Please help if any one can. Thanks in advance.

Also I forgot to mention, it says "Unregistered Android application" it means that the OAuth2 client ID I created is not found by the app but I don't know how can I make it find my OAuth2 client ID and solve my problem.

Answer 1

Please make sure that:-

• You enabled calendar API in google console for that project you are using, as the link provide in your response.
• Also match your package name in AndroidManifest is similar to the package you mentioned in google dev console with SHA.

Answer 2

Try to create an Oauth client id under corresponding project in google console. Follow the steps in this link.

To create an OAuth 2.0 client ID in the console:

1. Go to the Cloud Platform Console.
2. From the projects list, select a project or create a new one.
3. If the API Manager page isn't already open, open the console menu and select API Manager.
4. On the left, click Credentials.
5. Click New Credentials, then select OAuth client ID.

Note: If you're unsure whether OAuth 2.0 is appropriate for your project, select Help me choose and follow the instructions to pick the right credentials.

6. Select the appropriate application type for your project and enter any additional information required. Application types are described in more detail in the following sections.
7. If this is your first time creating a client ID, you can also configure your consent screen by clicking Consent Screen. (The following procedure explains how to set up the Consent screen.) You won't be prompted to configure the consent screen after you do it the first time.
8. Click Create client ID.

Based also from this related post, you have to give permission from your calendar configuration (Calendar configuration -> Share this calendar) to the email account specified into Google Api Console (email adress).

Hope this helps!
