I am trying to implement ZXing.Net.Mobile on for Android and having a runtime error.

        MobileBarcodeScanner scanner = new MobileBarcodeScanner(_activity);
        ZXing.Result result = await scanner.Scan(); // crashes here
        HandleZXingResult(result);

I use Xamarin for Visual Studio.

The issue seems to be about missing Resources and when it tries to SetContentView(layout). I am just using the ZXing Dlls. Not sure where to include the resources.

Stack Trace:

Не используйте NuGet для Android, попробуйте установить компоненты из Xamarin компонентов Store. Он работал для меня.

Я имел этот вопрос, потому что пакет ZXing NuGet сослались в сборке зависимостей (наш собственный штрих-код плагина сборки абстракции), но не в сборке родительского приложения. Реферировано пакет в обоих проектах, а затем он побежал отлично.
