[QUEST] Unable to use NetworkInterface

Hi everybody,

I'm making an app for Oculus Quest who need local networking and a broadcasting system... But I have a big problem...

I need to use the NetworkInterface and especially the NetworkInterface.OperationalStatus and
NetworkInterface.SupportsMulticast. But here is the problem, I can't use these functions. (I also use networkInterface.NetworkInterfaceType and networkInterface.Supports(NetworkInterfaceComponent.IPv4) and it works as expected).


When I use logcat with the Quest, I have errors when one of these functions is called :

10-22 09:56:18.144  5269  5269 W UnityMain: type=1400 audit(0.0:19): avc: denied { getattr } for path="/sys/devices/virtual/net/lo/flags" dev="sysfs" ino=27775 scontext=u:r:untrusted_app:s0:c512,c768 tcontext=u:object_r:sysfs:s0 tclass=file permissive=0

10-22 09:56:18.144  5269  5269 W UnityMain: type=1400 audit(0.0:20): avc: denied { getattr } for path="/sys/class/net/lo" dev="sysfs" ino=27754 scontext=u:r:untrusted_app:s0:c512,c768 tcontext=u:object_r:sysfs:s0 tclass=lnk_file permissive=0


The untrusted_app reason made me think it was from a missing permission, but I add all of these permissions to my AndroidManifest and doesn't works better :

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.UPDATE_DEVICE_STATS" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_MULTICAST_STATE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />


I also made this little script to ask for the autorisation if the app doesn't have it, but it only asking for the writing permission, no other...


    void Start()
    {
        #if PLATFORM_ANDROID
        if (!Permission.HasUserAuthorizedPermission(Permission.ExternalStorageWrite))
        {
            Permission.RequestUserPermission(Permission.ExternalStorageWrite);
        }

        if (!Permission.HasUserAuthorizedPermission("android.permission.INTERNET"))
        {
            Permission.RequestUserPermission("android.permission.INTERNET");
        }

        if (!Permission.HasUserAuthorizedPermission("android.permission.ACCESS_WIFI_STATE"))
        {
            Permission.RequestUserPermission("android.permission.ACCESS_WIFI_STATE");
        }

        if (!Permission.HasUserAuthorizedPermission("android.permission.UPDATE_DEVICE_STATS"))
        {
            Permission.RequestUserPermission("android.permission.UPDATE_DEVICE_STATS");
        }

        if (!Permission.HasUserAuthorizedPermission("android.permission.ACCESS_NETWORK_STATE"))
        {
            Permission.RequestUserPermission("android.permission.ACCESS_NETWORK_STATE");
        }

        if (!Permission.HasUserAuthorizedPermission("android.permission.CHANGE_WIFI_MULTICAST_STATE"))
        {
            Permission.RequestUserPermission("android.permission.CHANGE_WIFI_MULTICAST_STATE");
        }

        if (!Permission.HasUserAuthorizedPermission("android.permission.CHANGE_WIFI_STATE"))
        {
            Permission.RequestUserPermission("android.permission.CHANGE_WIFI_STATE");
        }
        #endif
    }


Someone has an idea how to get around this problem ?... I really need to use NetworkInterface and broadcasting between any devices (PC or Quest).

Thanks a lot for your help in coming !
