Implement Bluetooth MAP in Android ContentProvider

I have a custom SMS Android app. As a new feature I want to display new messages on car entertainment systems that are connected via Bluetooth and support Bluetooth MAP-Protocol. Therefore I need an expert with experience in implementing Bluetooth applications on Android to complete the following task: Create a Java Class that implements an Android ContentProvider. This ContentProvider shall pushe messages (text strings) to a connected Bluetooth device via MAP protocol (using MessageAccessService and MessageNotificationService). The ContentProvider shall act as a Message Server Equipment (MSE), notifying connected clients of changes as well as allowing clients to query it for available messages. Messages shall have the type GSM-SMS. Any Android APIs available in Android version 22 or lower can and should be used.
