Unable to share photo in Facebook

I am taking a photo using an Android phone, and I want to post it in Facebook. My code:

private void SharePhotoFacebook(Bitmap bmp) {
    FacebookSdk.sdkInitialize(FaceActivity.this);
    // Create a callbackManager to handle the login responses.
    callbackManager = CallbackManager.Factory.create();

    shareDialog = new ShareDialog(this);

    SharePhoto photo = new SharePhoto.Builder()
            .setBitmap(bmp)
            .build();
    if(ShareDialog.canShow(SharePhotoContent.class)){
        SharePhotoContent content = new SharePhotoContent.Builder()
                .addPhoto(photo)
                .build();
        shareDialog.show(content);
    }

    // this part is optional
    shareDialog.registerCallback(callbackManager, new FacebookCallback<Sharer.Result>() {
        @Override
        public void onSuccess(Sharer.Result result) {
            Log.i("David", "Éxito");
        }

        @Override
        public void onCancel() {

        }

        @Override
        public void onError(FacebookException error) {
            Log.i("David", "Error");
        }
    });
}

But no dialog is showing, and nothing is posted in Facebook. I have implemented this code in the same Activity I take photo (FaceActivity), and is the Activity declared in Facebook Developer page of the app. What is wrong?

I can see like something tries to show (a grey "flash" that appears in the screen) but nothing shows.

EDIT: Im taking photo this way:

makePhoto.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            mCameraSource.takePicture(null, new CameraSource.PictureCallback() {
                @Override
                public void onPictureTaken(@NonNull byte[] bytes) {
                    Log.i("David", String.valueOf(bytes.length));
                    bmp= BitmapFactory.decodeByteArray(bytes,0,bytes.length);
                    ShowShareDialog();
                    //SharePhotoFacebook(bmp);
                }
            });
        }
    });

I just realized I have this in my debug:
