I\'m working with some sample code here:

Look into your AndroidManifest file.
You can revoke account permissons on ...
https://security.google.com/settings/security/permissions
You can get there by [Account Settings] > [Account Permissions]
Proof that this answer is the real deal:
It's not possible via any public, official API.
See:
Even uninstalling and re-installing the app doesn't help.
This might be the way on a rooted device: How do you force AccountManager to show the "Access Request" screen after a user has already allowed access?
I believe if you go to https://accounts.google.com/IssuedAuthSubTokens it should list your application under "Connected Sites, Apps and Services" from there you can revoke access.
Using Google Play Services:
http://developer.android.com/reference/com/google/android/gms/auth/GoogleAuthUtil.html
Add https://www.googleapis.com/auth/userinfo.profile to your scope.
Example:
String scope="oauth2:https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile"
final String token = GoogleAuthUtil.getToken(context, "xxxx@gmail.com", scope);
OR "brute force"
Intent res = new Intent();
res.addCategory("account:xxxx@gmail.com");
res.addCategory("scope:oauth2:https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile");
res.putExtra("service", "oauth2:https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile");
Bundle extra= new Bundle();
extra.putString("androidPackageName","com.your.package");
res.putExtra("callerExtras",extra);
res.putExtra("androidPackageName","com.your.package");
res.putExtra("authAccount","xxxx@gmail.com");
String mPackage = "com.google.android.gms";
String mClass = "com.google.android.gms.auth.TokenActivity";
res.setComponent(new ComponentName(mPackage,mClass));
startActivityForResult(res,100);
Now, when you revoke the access here https://accounts.google.com/IssuedAuthSubTokens the application shows you the window for permission again in the device.
Two steps to trigger the authorization page again:
