Android Telephony User Application

I assume this is the correct forum, not android.stackechange, as it is software related.

I am a beginner Java developer and you need to create your own Android telephony application with the following functionality

  • starts automatically when the device starts, loads
  • It starts in kiosk mode, without notifications or access to other applications!
  • has a “call” button that places a phone call on a telephone number with a wired telephone connection.
  • has the ability to transfer one-way simple data to an external device (think arduino) via bluetooth. that is, when a call signal is received to arduino to blink, etc.
  • optional display for hard-coded message or received number.

Should I use one Activity class?
What other classes should I create or use?
To correctly test both incoming and outgoing calls, you first need to deploy to the actual device with an initialized (with phone number) SIM?

Are there any Android projects on Github or elsewhere that have parts of this functionality that I can learn and study?

Any other architecture tips or suggestions?

        Intent intent = new Intent(context, YourActivity.class);
        context.startActivity(intent);
    }
}
