Android Facebook 4.0：检查权限

Question

Many things been changed in Facebook 4.0.

How to check if user have permission in Facebook 4.x api?

Answer 1

Found it :

People can grant only a subset of permissions that you ask for, except for public profile, which is granted at login.

People can also revoke permissions granted to your app in Facebook's interface at any time after they have logged in. So your app should regularly check which permissions have been granted. We provide methods for you to check what permissions are currently granted to your app.

To get the list of permissions associated with the current access token, call:

AccessToken.getCurrentAccessToken().getPermissions()

Note that AccessToken.getCurrentAccessToken() can be null

Answer 2

After Successfull Login Call this method

    new GraphRequest(
        AccessToken.getCurrentAccessToken(),
        "/{user-id}/permissions",
        null,
        HttpMethod.GET,
        new GraphRequest.Callback() {
            public void onCompleted(GraphResponse response) {
                /* handle the result */
            }
        }
    ).executeAsync();

 new GraphRequest(
                AccessToken.getCurrentAccessToken(),

                null,
                HttpMethod.GET,
                new GraphRequest.Callback() {
                    public void onCompleted(GraphResponse response) {
                        CommonMethod.showAlert("PERMISSION_GRANTED Fb ---> " + response, MainActivity.this);
                    }
                }
        ).executeAsync();
