Question

I want to know when user has connected hands free accessories and hasn’t blocked calls\sms. Is it possible to know when it is connected via hardware ports or bluetooth?

Answer 1

Try this in your onCreate or onResume.

    BluetoothAdapter myLocalAdapter = BluetoothAdapter.getDefaultAdapter();
    BluetoothDevice garniture;
    Set<BluetoothDevice> connectedDevices = myLocalAdapter.getBondedDevices();
    for (BluetoothDevice device : connectedDevices){
        String name = device.getName();
        //...  check for the name you want
        if( name.equals("whatnameisit"){
             garniture = device
        } 
    }
    if (garniture != null){
        // yay we found it,  lets do our work with the device here 
    }
