I’m trying to design a simple app that launches installation of a previously download apk file (for update purpose of another app).

This app has one button to launch the update.

Here is what i found and tried but without success :

        string s = Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryDownloads).AbsolutePath;
        string path = s + "/TPAndroid-Signed.apk";


        Android.Net.Uri apkUri = Android.Net.Uri.Parse(path);
        Intent intent = new Intent(Intent.Action);
        intent.SetDataAndType(apkUri, "application/vnd.android.package-archive");
        intent.SetFlags(ActivityFlags.NewTask);
        intent.AddFlags(ActivityFlags.GrantReadUriPermission);
        intent.AddFlags(ActivityFlags.GrantPrefixUriPermission);
        intent.AddFlags(ActivityFlags.GrantPersistableUriPermission);
        StartActivity(intent);

Thank you for your help.
