如何强制facebook android 4.x sdk让用户重新输入其凭据？

Question

There are many questions & answers related to the subject, but very few specific to Facebook's Android 4.x SDK.

What I want to do is, after I call LoginManager.getInstance().logOut(), I want the user to have to re-authenticate in order to create a new AccessToken.

I am seeing that after I call LoginManager.getInstance().logOut() I am not prompted for credentials the next time I call LoginManager.getInstance().logInWithReadPermissions(...).

Anyone know how to force LoginManager to have the user re-authenticate?

Answer 1

The Facebook process confused me for ages as it doesn't appear to be clearly explained, and as you point out, most of the questions are for SDK 3.

But as far as I can see the only way that the user needs to re-authenticate is if they go to

Facebook->Settings->Apps

and in App Settings click remove for the app.

If they have approved the App for login once then no matter what happens with the App on the Android device, provided that you follow the correct usage of LoginManager, it never prompts the use to re-authenticate.
