I'm developing an android application where the person can log in via Facebook.
I'm trying to develop the "share" option so that an application message can be posted on the user's timeline, but I'm encountering the following error:
Session: an attempt was made to request new permissions for a session that has a pending request
I believe the error is at the moment when I try to request permission to publish to the user. Here is the code below, where authentication and the facebook share process are done:
Main activity
public class MainActivity extends FragmentActivity {
private MainFragment mainFragment;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (savedInstanceState == null) {
// Add the fragment on initial activity setup
mainFragment = new MainFragment();
getSupportFragmentManager()
.beginTransaction()
.add(android.R.id.content, mainFragment)
.commit();
} else {
// Or set the fragment from restored state info
mainFragment = (MainFragment) getSupportFragmentManager()
.findFragmentById(android.R.id.content);
}
}
}
Fragment:
public class MainFragment extends Fragment{
private static final String TAG = "MainFragment";
private UiLifecycleHelper uiHelper;

authButton.setFragment(this);
authButton.setReadPermissions(Arrays.asList("user_likes", "user_status"));
if (savedInstanceState != null) {
pendingPublishReauthorization =
savedInstanceState.getBoolean(PENDING_PUBLISH_KEY, false);
}
shareButton = (Button) view.findViewById(R.id.shareButton);

Login is successful, but when I click on share, the application does not request the new permissions, just saying that I already authorized the app, and it gives the error.
From what I understood. It is not adding the publishing permission and is making the same request again, resulting in the error.
Can anyone help?
