@ayalma does the download ever complete or are you stuck waiting for the model indefinitely? Also is this specific to a certain device or network?

[ayalma]

Yes , it's stuck in waiting.
I tested in my friend Lg device and problem exist.
And for network i tested it with wifi and mobile date and even i used vpn for that and still this problem exist .

[carlosgub]

This happens to me one time, I only w8 like 10 minutes because the device is downloading the model, and later work without problem

[the-dagger]

@samtstern I think that this issue also ties in with #586

[samtstern]

@the-dagger I can confirm we're making some internal progress on #586, I've seen some good API proposals going around!

[the-dagger]

Awesome, thanks!

[FarshidRoohi]

I also have this problem(any devices)
there is a solution?

implementation 'com.google.firebase:firebase-core:16.0.6'
implementation 'com.google.firebase:firebase-ml-vision:18.0.2'

take image and call method

   mCamera.takePicture(null, null, new Camera.PictureCallback() {
     @Override
       public void onPictureTaken(byte[] bytes, Camera camera) {
              Bitmap bitmap = BitmapFactory.decodeByteArray(bytes, 0, bytes.length);
               ByteArrayOutputStream stream = new ByteArrayOutputStream();
               bitmap.compress(Bitmap.CompressFormat.JPEG, 1, stream);
               imageView.setImageBitmap(bitmap);
               fetch(bitmap);
     }
 });

 private void fetch(Bitmap bitmap) {
        final FirebaseVisionImage    firebaseVisionImage          = FirebaseVisionImage.fromBitmap(bitmap);
        FirebaseVisionTextRecognizer firebaseVisionTextRecognizer = FirebaseVision.getInstance().getOnDeviceTextRecognizer();

        firebaseVisionTextRecognizer.processImage(firebaseVisionImage)
                .addOnSuccessListener(new OnSuccessListener<FirebaseVisionText>() {
                    @Override
                    public void onSuccess(FirebaseVisionText firebaseVisionText) {
                        btn.setEnabled(true);
                        Log.i(TAG, "onFailure: " + firebaseVisionText.getText());

                    }
                }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                btn.setEnabled(true);
                e.printStackTrace();
                Log.i(TAG, "onFailure: " + e.getMessage());
            }
        });
    }

_error message_ : Waiting for the text recognition model to be downloaded. Please wait.

There doesn't seem to be evidence here that anything is broken, models can sometimes take a long time to download on a slower or spottier connection. Let's close this and I will update on when we have a better API for these downloads in #586.

[hardysim]

This pops up for me after trying on-device OCR on Android 11 DP 1.

On previous versions, everything worked fine (the models are also mentioned in the manifest to be downloaded via com.google.firebase.ml.vision.DEPENDENCIES).

But it seems that even with FirebaseModelManager I cannot check the status of on-device models (see firebase/firebase-android-sdk#47)?!

Is this a known problem with Android 11?

[shubh261096]

Add this dependency. It worked for me.
implementation 'com.google.firebase:firebase-ml-vision-barcode-model:16.0.2'

[hardysim]

This might be a workaround. But the auto-download will be fixed, right?

@shubh261096 which dependency do I need for OCR?

[kDmartel]

Do you have a workaround? @samtstern samtstern

[JeetSA]

I am having the same issue. Can anyone please help me?
