How to disable Mobile Data on Android with Xamarin

similar question to How to disable Mobile Data on Android . the only difference is that i want to do that with Xamarin but not java.

I tried the code below but it did nothing.

        var conn = ApplicationContext.GetSystemService(ConnectivityService).JavaCast<ConnectivityManager>();
        var connState = conn.StopUsingNetworkFeature(ConnectivityType.Mobile, "");

so my question is that: is there anyway to disable Mobile Data on Android with xamarin? or is there anyway to use "java reflection technique". with xamarin?

In xamarin android you can use like this if you want to disable the mobile cellular data.

TelephonyManager tm = (TelephonyManager)Android.App.Application.Context.GetSystemService(Context.TelephonyService);
 
var tdata = tm.DataEnabled;
if (tdata)
    tdata = false;

Typically Xamarin uses the same methodology as Java when interacting with Android. Therefore its best to just port over the equivalent Java code to C#; in this case translating the reflection code in the answer you linked to.

Here is a port that combines Gingerbread and higher support and Froyo and lower support:

void SetMobileDataEnabled(bool enabled)
{
    if (Build.VERSION.SdkInt >= Android.OS.BuildVersionCodes.L) {
        Console.WriteLine ("Device does not support mobile data toggling.");
        return;
    }

    try {
        if (Build.VERSION.SdkInt <= Android.OS.BuildVersionCodes.KitkatWatch 
            && Build.VERSION.SdkInt >= Android.OS.BuildVersionCodes.Gingerbread) {
            Android.Net.ConnectivityManager conman = (Android.Net.ConnectivityManager)GetSystemService (ConnectivityService);
            Java.Lang.Class conmanClass = Java.Lang.Class.ForName (conman.Class.Name);
            Java.Lang.Reflect.Field iConnectivityManagerField = conmanClass.GetDeclaredField ("mService");
            iConnectivityManagerField.Accessible = true;
            Java.Lang.Object iConnectivityManager = iConnectivityManagerField.Get (conman);
            Java.Lang.Class iConnectivityManagerClass = Java.Lang.Class.ForName (iConnectivityManager.Class.Name);
            Java.Lang.Reflect.Method setMobileDataEnabledMethod = iConnectivityManagerClass.GetDeclaredMethod ("setMobileDataEnabled", Java.Lang.Boolean.Type);
            setMobileDataEnabledMethod.Accessible = true;

            setMobileDataEnabledMethod.Invoke (iConnectivityManager, enabled);
        }

        if (Build.VERSION.SdkInt < Android.OS.BuildVersionCodes.Gingerbread) {

            TelephonyManager tm = (TelephonyManager)GetSystemService (Context.TelephonyService);

            Java.Lang.Class telephonyClass = Java.Lang.Class.ForName (tm.Class.Name);
            Java.Lang.Reflect.Method getITelephonyMethod = telephonyClass.GetDeclaredMethod ("getITelephony");
            getITelephonyMethod.Accessible = true;

            Java.Lang.Object stub = getITelephonyMethod.Invoke (tm);
            Java.Lang.Class ITelephonyClass = Java.Lang.Class.ForName (stub.Class.Name);

            Java.Lang.Reflect.Method dataConnSwitchMethod = null;
            if (enabled) {
                dataConnSwitchMethod = ITelephonyClass
                    .GetDeclaredMethod ("disableDataConnectivity");
            } else {
                dataConnSwitchMethod = ITelephonyClass
                    .GetDeclaredMethod ("enableDataConnectivity");   
            }

            dataConnSwitchMethod.Accessible = true;
            dataConnSwitchMethod.Invoke (stub);
        } 
    } catch (Exception ex) {
        Console.WriteLine ("Device does not support mobile data toggling.");
    }
}

Enable the ChangeNetworkState and ModifyPhoneState permissions in your manifest.

Android L currently has no available way to disable/enable mobile data.
