Android Facebook api 3.0 error: Cannot call LoginActivity with a null calling package

Question

I am trying to integrate an android app with the the new facebook 3.0 api, but I get this exception:

java.lang.RuntimeException: Unable to resume acti

Answer 1

I've got the same problem : trying to log into facebook, with the dialog provided inside the SDK, but from an activity that was itself inside a tabgroup ; like ShareActivity above.

What I've done is basically called startActivityForResult on parent activity of ShareActivity (that is ShareGroupActivity), instead of calling it on ShareActivity.

So 1 , add this in ShareGroupActivity :

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    System.out.println("facebook status called");
    super.onActivityResult(requestCode, resultCode, data);
    Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}

2 you need to modify the class Session, inside FacebookSDK project, under src com.facebook

2.1 add a boolean member

public boolean insideTabGroup;

2.2 modify StartActivityDelegate, that is used by session to open login ; add the boolean as parameter

interface StartActivityDelegate {
    public void startActivityForResult(Intent intent, int requestCode, boolean insideTabGroup);

    public Activity getActivityContext();
}

2.3 inside the inner class AuthorizationRequest, modify the implementation of this delegate :

    AuthorizationRequest(final Activity activity) {
        startActivityDelegate = new StartActivityDelegate() {
            @Override
            public void startActivityForResult(Intent intent, int requestCode, boolean insideTabGroup) {
                if(insideTabGroup) {
                    ActivityGroup parentActivity = (ActivityGroup) activity.getParent();
                    parentActivity.startActivityForResult(intent,requestCode);

                } else {
                    activity.startActivityForResult(intent, requestCode);
                }
            }

            @Override
            public Activity getActivityContext() {
                return activity;
            }
        };
    }

2.4 Also, modify the other constructors of AuthorizationRequest, by just adding the boolean parameter. As I do not use login to facebook from somewhere else than an activity, that's ok.

2.5 Modifiy the tryLoginActivity method of Session class, to use the boolean member as a parameter :

private boolean tryLoginActivity(AuthorizationRequest request) {
    Intent intent = getLoginActivityIntent(request);

    if (!resolveIntent(intent)) {
        return false;
    }

    try {
        request.getStartActivityDelegate().startActivityForResult(intent, request.getRequestCode(),this.insideTabGroup);

    } catch (ActivityNotFoundException e) {
        return false;
    }

    return true;
}

3 Set the boolean member in the session :

Session session = Session.getActiveSession();
session.insideTabGroup = true;

That should do the trick.
