Guide for android.permission

[SalimiHabib]

i cannot find

<uses-permission android:name="android.permission.BIND_VPN_SERVICE" />

in sample android manifest in official repo and also cannot find how permission will request from user , do i can use VpnHoodApp , or it must write by my self .

it seems repo is different from published version (may be security consideration ) , am i right ? normally VpnHoodApp.Instance.Connect() must ask for permission when calling for CreatePacketCapture()

// create packet capture
var packetCapture = await Device.CreatePacketCapture();
if (packetCapture.IsMtuSupported)
    packetCapture.Mtu = TunnelDefaults.MtuWithoutFragmentation;

but it not happening and i get exception Exception("Please open the app and grant VPN permission to proceed.");

thank you

It is. give me time i will create the MAUI scaffold for you. You just need to implement its UI. No need for implementing permissions or so on.

i will be thankful

just want you to know : we test VpnHoodClientand VpnHoodAppseparately and in both class we ended to permission error .

we try to solve vpn permission by having a service as below , but even i get Grant permission , we get permission denied error on VpnHoodClient and VpnHoodApp ( after using connect method ).

android manifest android:permission="android.permission.BIND_VPN_SERVICE"

vpnpermission.cs

public class VpnServicePermission : Permissions.BasePlatformPermission
{
    public override (string androidPermission, bool isRuntime)[] RequiredPermissions => new List<(string androidPermission, bool isRuntime)>
    {
        (Android.Manifest.Permission.BindVpnService, false)
    }.ToArray();
}

 public class PermissionService : IPermissionService
{
    Context? context;
    public PermissionService()
    {
        context = Android.App.Application.Context;
    }
    public bool IsPermissionGranted(string permission)
    {
        var result = context.CheckSelfPermission(permission);
        return result == Permission.Granted;
    }
    public async Task  CheckAndRequestVpnServicePermission()
    {
        try
        {
            var permission = Manifest.Permission.BindVpnService;
            var status = ContextCompat.CheckSelfPermission(context, permission);
            if (status == Permission.Granted)
            {
                return  ;
            }
            else
            {  // Request permission
                var currentActivity = Microsoft.Maui.ApplicationModel.Platform.CurrentActivity;
                ActivityCompat.RequestPermissions(currentActivity, new string[] { permission }, 1);

            }
            return;
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
#if DEBUG
            throw;
#endif

#if !DEBUG
         return false;
#endif

        }
    }
}

part of connect method

 var packetCapture = await Device.CreatePacketCapture();

 _vpnHoodClient = new VpnHoodClient(packetCapture, clientId.Value, accessKeyToken, new ClientOptions());

 _vpnHoodClient.StateChanged += (_, _) => UpdateUi();

 await _vpnHoodClient.Connect();_

thank you

Please give me a couple of days. I am working on it.
