I am currently working on an Android application (written in Java) using Google ML and TensorFlow. The application is centered around object detection during a live camera stream using the device camera, and uses a TensorFlow Lite model as a custom library to source file lists from. The TensorFlow Lite model specifically is called mobilenet_v1_0.75_192_quantized_1_metadata_1.tflite which I got here 2. My issue is that I ran the application to see if it would print the list size, and the application launches just fine; camera preview works, app doesn’t crash. However, when looking for the list size in the logcat, only these following errors are printed in my Logcat;

According to my research, some results state that that the file path or root is flawed in some capacity. However, I have the .tflite model placed within my asset folder, which leads me to wonder why exactly I’m receiving these errors and how I can work on resolving them. My Log.d("TAG", "onSuccess" + detectedObjects.size()); in my code below is supposed to print the object list size, but is clearly not. Here is my MainActivity.java;
public class MainActivity extends AppCompatActivity {

    private class YourAnalyzer implements ImageAnalysis.Analyzer {

        @Override
        @ExperimentalGetImage
        public void analyze(ImageProxy imageProxy) {
            Image mediaImage = imageProxy.getImage();
            if (mediaImage != null) {
                InputImage image =
                        InputImage.fromMediaImage(mediaImage, imageProxy.getImageInfo().getRotationDegrees());
                //Pass image to an ML Kit Vision API
                //...

                LocalModel localModel =
                        new LocalModel.Builder()
                        .setAssetFilePath("mobilenet_v1_0.75_192_quantized_1_metadata_1.tflite")
                        .build();

                CustomObjectDetectorOptions customObjectDetectorOptions =
                        new CustomObjectDetectorOptions.Builder(localModel)
                        .setDetectorMode(CustomObjectDetectorOptions.STREAM_MODE)
                        .enableClassification()
                        .setClassificationConfidenceThreshold(0.5f)
                        .setMaxPerObjectLabelCount(3)
                        .build();

                ObjectDetector objectDetector =
                        ObjectDetection.getClient(customObjectDetectorOptions);

                objectDetector.process(image)
                        .addOnSuccessListener(detectedObjects -> {
                            Log.d("TAG", "onSuccess" + detectedObjects.size());
                        })
                        .addOnFailureListener(e -> Log.e("TAG", e.getLocalizedMessage()))
                        .addOnCompleteListener(result -> imageProxy.close());
            }
        }
    }

    private ListenableFuture<ProcessCameraProvider> cameraProviderFuture;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        cameraProviderFuture = ProcessCameraProvider.getInstance(this);

        cameraProviderFuture.addListener(() -> {
            try {
                ProcessCameraProvider cameraProvider = cameraProviderFuture.get();
                bindPreview(cameraProvider);
            } catch (ExecutionException | InterruptedException e) {

            }
        }, ContextCompat.getMainExecutor(this));
    }

    void bindPreview(@NonNull ProcessCameraProvider cameraProvider) {

        PreviewView previewView = findViewById(R.id.previewView);
        Preview preview = new Preview.Builder()
                .build();

        CameraSelector cameraSelector = new CameraSelector.Builder()
                .requireLensFacing(CameraSelector.LENS_FACING_BACK)
                .build();

        preview.setSurfaceProvider(previewView.getSurfaceProvider());

        Camera camera = cameraProvider.bindToLifecycle((LifecycleOwner)this, cameraSelector, preview);
    }
}

Also, just for clarification, my application name is ObjectDetection and the IDE that I’m working on is Android Studio. This is how the .tflite model is placed within my asset folder; ObjectDetection > app > src > main > assets > ClassifierModel.tflite
