MLKit BarCode Sanner Implementation results in internal error when executing ML Kit tasks

Question

Every call to scanner.process(image) is resulting in the onFailure call, with the following error:

Error:com.google.mlkit.common.MlKitException: Internal

Answer 1

Inadvertently found the cause of the error by reading this. Adding an OnCompleteListener to the result Task and placing the imageProxy.close() inside, resolved this. i.e.:

Errors

Task<List<Barcode>> result = scanner.process(image);

result.addOnSuccessListener(new OnSuccessListener<List<Barcode>>() {
    @Override
    public void onSuccess(List<Barcode> barcodes) {
        // Task completed successfully
        Log.i("CameraXApp3", "scanner task successful");
        processBarCodes(barcodes);
    }
}).addOnFailureListener(new OnFailureListener() {
    @Override
    public void onFailure(@NonNull Exception e) {
        // Task failed with an exception
        Log.i("CameraXApp3", "scanner task failed. Error:" + e);

    }
});
mediaImage.close();
imageProxy.close();

No Errors

Task<List<Barcode>> result = scanner.process(image);

result.addOnSuccessListener(new OnSuccessListener<List<Barcode>>() {
    @Override
    public void onSuccess(List<Barcode> barcodes) {
        // Task completed successfully
        Log.i("CameraXApp3", "scanner task successful");
        processBarCodes(barcodes);
    }
}).addOnFailureListener(new OnFailureListener() {
    @Override
    public void onFailure(@NonNull Exception e) {
        // Task failed with an exception
        Log.i("CameraXApp3", "scanner task failed. Error:" + e);

    }
}).addOnCompleteListener(new OnCompleteListener<List<Barcode>>() {
    @Override
    public void onComplete(@NonNull Task<List<Barcode>> task) {
        mediaImage.close();
        imageProxy.close();
    }
});

Will wait to mark as answer in case @Hoi wants to grab the points, which he deserves. :)
