Here, the TextRecognizer returns false, my application does not continue to run

 protected override void OnCreate(Bundle bundle)
            base.OnCreate(bundle);
            // Set our view from the "main" layout resource
            SetContentView(Resource.Layout.Main);
            cameraView = FindViewById<SurfaceView>(Resource.Id.surface_view);
            textView=FindViewById<TextView>(Resource.Id.text_view);
            TextRecognizer textRecognizer=new TextRecognizer.Builder(ApplicationContext).Build();
            if (!textRecognizer.IsOperational)
                Log.Error("Error","Hata var");
                cameraSource = new CameraSource.Builder(ApplicationContext, textRecognizer)
                    .SetFacing(CameraFacing.Back)
                    .SetRequestedPreviewSize(1280, 1024)
                    .SetRequestedFps(2.0f)
                    .SetAutoFocusEnabled(true)
                    .Build();
                cameraView.Holder.AddCallback(this);
                textRecognizer.SetProcessor(this);
All the permissions for devices are open still the App is not able to run on two different devices
LG-Android Version 7.0
Samsung-Android Version 4.2.1
Help me please!
You are never creating/setting the OCR processor on your TextRecognizer instance. Once you do that, the Google Play services will also be able to download the correct models to the device if they are not already available.
textRecognizer.SetProcessor(new OcrDetectorProcessor(_GraphicOverlay));
You will need to subclass Detector.Processor and implement the ReceiveDetections (override) method.
