Is it possible to change the android attribute <host-apdu-service> android: requireDeviceUnlock at run time?

Question

The Android NFC HCE HostApduService is configured through apduservice.xml, which contains:

<host-apdu-service xmlns:android="http://schemas.android.com/apk/res/android"
    android:description="@string/servicedesc"
    android:requireDeviceUnlock="true" >

    <aid-group
        android:category="other"
        android:description="@string/aiddescription" >
        <aid-filter android:name="F0010203040506" />
    </aid-group>

</host-apdu-service>

I want to make requireDeviceUnlock a user-configurable parameter at runtime. I suspect that I can forcefully reload the XML file by restarting the service with:

stopService(new Intent(this, MyHostApduService.class));
startService(new Intent(this, MyHostApduService.class));

But how to change the parameter in the XML file at runtime?

Answer 1

I really looked at the implementation of the same functionality, i.e. for this, user preference required unlocking the device or not.

However, looking at the api

https://developer.android.com/reference/android/nfc/cardemulation/HostApduService.html

, , "requireDeviceUnlock", apduservice.xml .

, .

false, apduservice sharedpreference, , , / .
