Question

Created a test app using Eclipse to get the authToken from one of my google e-mail accounts on my device.

Executing this prompted me with the allow access dialog where i press allow access:

accountManager.getAuthToken(account,"oauth2:https://www.googleapis.com/auth/userinfo.profile", false, new GetAuthTokenCallback(), null);

I wanted to create a chooser dialog that works from API8 and up where the user can choose
what google account he allow me to access. To do this i have to revoke the permission to see the screen again.

should i see my test app on this page or not?
Authorized Access to your Google Account

I have search for a way to revoke the permission and non is working..
Only thing working is to create a new app project.

UPDATE 2013
Using the Google Play service GCM and this is working ok

Answer 1

Regarding the “Authorized Access to your Google Account” page, you will not see your app there as this permission is a device local permission stored in a database on the phone.

It does not seem like it is possible to revoke this permission in an easy way. I’ve been able to find a couple of ways to be able to trigger the dialog again, but none are ideal. In some of these solutions it’s not the exact same dialog that is shown, but it might be close enough for testing purposes depending on what you want to do:

• Do a factory reset of the phone.
• Create a new minimal test app and configure both apps to share the same UID. This means that both apps will be granted the same permissions and the dialog will be shown again to let the user allow your second app access as well.
• Add an additional scope to the token type (e.g. change oauth2:https://www.googleapis.com/auth/userinfo.profile to oauth2:https://www.googleapis.com/auth/userinfo.profile https://www.googleapis.com/auth/userinfo.email). Since you are asking for additional permissions the dialog will be shown again.
• Given that you have root access to your phone delete the table grants from the database /data/system/accounts.db which is where the granted permissions are stored as explained in How do you force AccountManager to show the "Access Request" screen after a user has already allowed access?

Internally the getAuthToken method keeps track of if access has been granted or not using the UID of the application. So if you are able to somehow force Android to give your app a new UID or to force it to clear the database of given grants the dialog should be shown again. Here are some solutions that others say work for them but that doesn’t work for me (maybe it depends on which phone you use?):

• Uninstall the app and restart the device (as you say)
• Remove and re-add the google account (mentioned in Revoke account permission for an app)
• Sign the app with a different certificate (also mentioned in Revoke account permission for an app)

As a side note as revoke permissions to access google auth tokens mention there are internal Android methods for revoking access, but these are not accessible via the public API.
