Answer 1

I am using the following code and is working fine... but After inviting friends (if you've shared android application then invitee have to check on his/her mobile application..) the invitation is not visible through browsers

private CallbackManager sCallbackManager;

public void openDialogInvite(final Activity activity) {
            String AppURl = "https://fb.me/421570...5709";  //Generated from //fb developers

        String previewImageUrl = "http://someurl/13_dp.png";

        sCallbackManager = CallbackManager.Factory.create();

        if (AppInviteDialog.canShow()) {
            AppInviteContent content = new AppInviteContent.Builder()
                    .setApplinkUrl(AppURl).setPreviewImageUrl(previewImageUrl)
                    .build();

            AppInviteDialog appInviteDialog = new AppInviteDialog(activity);
            appInviteDialog.registerCallback(sCallbackManager,
                    new FacebookCallback() {
                        @Override
                        public void onSuccess(AppInviteDialog.Result result) {
                            Log.d("Invitation", "Invitation Sent Successfully");
                            finish();
                        }

                        @Override
                        public void onCancel() {
                        }

                        @Override
                        public void onError(FacebookException e) {
                            Log.d("Invitation", "Error Occured");
                        }
                    });

            appInviteDialog.show(content);
        }

    }
