        an incorrect application ID
        results
        in failure when the client tries to activate

                                                – leave the application ID empty. 
 
- 2.1 or later – use preexisting
                                                HWC
                                                template, or, if
                                                you
                                                are using your own template, make
                                                sure that
                                                HWC
                                                is set as the application ID in the template.

                                                container 2.1 or later – use the template you have
                                                created. The application ID used by the iOS sample
                                                container should match the application ID specified
                                                in registration.

                                    - Previous to 2.1.2 – leave the
                                            application ID empty. This applies to native
                                            messaging-based application
                                            clients.
 
- 2.1.2 or later – (recommended) use the
                                            application connection template that is automatically
                                            created for the application. Otherwise, ensure you
                                            register
                                            the
                                            application connection with the
                                            correct template by verifying that application
                                            ID
                                            matches, and that the correct security configuration and
                                            domain are selected. Also, if using
                                            replication,
                                            set other template properties (such as
                                            synchronization-related properties in Connection
                                            category) as required. For Android native MBO
                                            applications,
                                            this recommendation applies starting with
                                            version
                                            2.1.1.
