Facebook App Invite, Invite Friends

Question

I switched to Facebook 4.0 in order to implement AppInviteDialog for Android. I followed this reference.

The dialog appears, I can select friends, invite them, I get the onSuccess() call, but my friends don't get the invite.

I have used the below applink URL: https://fb.me/****412097*****

No previewImageURL although I saw my app's image on the dialog.

Code:

//Inside onCreate -

        callbackManager = CallbackManager.Factory.create();

        mInvititeDialog = new AppInviteDialog(this);
        mInvititeDialog.registerCallback(callbackManager,
                new FacebookCallback<AppInviteDialog.Result>() {

                    @Override
                    public void onSuccess(Result result) {
                        NetworkController.showCustomToast(
                                InviteFriendsActivity.this,
                                "Invitation Sent Successfully!");
                        finish();
                    }

                    @Override
                    public void onCancel() {
                        Log.d("Result", "Cancelled");
                        NetworkController.showCustomToast(
                                InviteFriendsActivity.this, "Cancelled");
                        finish();
                    }

                    @Override
                    public void onError(FacebookException exception) {
                        Log.d("Result", "Error " + exception.getMessage());
                        NetworkController.showCustomToast(
                                InviteFriendsActivity.this,
                                "Error while inviting friends");
                        finish();
                    }
                });


    if (AppInviteDialog.canShow()) {
            AppInviteContent content = new AppInviteContent.Builder()
                            .setApplinkUrl(appLinkUrl).build();

            AppInviteDialog.show(InviteFriendsActivity.this, content);

    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);
        callbackManager.onActivityResult(requestCode, resultCode, data);

    }

Facebook App Invite not received

Answer 1

Ok, turns out everything was working fine after all. My mistake was in assuming not having the app installed, and not having the app authorized should generate a push notification.

After creating a new test user, using a device where the app was not currently installed and the app NEVER having been authorized with the user.

So the key here is that no push notification will be generated if the app is installed on the target device, even if the user has not authorized the app previously. Also, seemingly, if the user has authorized the app previously, even if it was removed it at some point, it also will not generate a notification.

So if you want to test this, create an entirely new test user and log in on the Facebook app on the platform you are testing on, and make sure the app is not installed on the device.

I think it should still generate a notification despite app being installed, because multiple users might be using the same device, but that's how it seems to be right now.

I'll leave this here in case anyone has a similar problem in the future.

Live long and prosper!

It did actually work for me, however I am not very sure if it covers all the scenarios and is the perfect solution. Posting here for other users and suggestions if any.
