I know I am last at the party, but If anyone is still facing this error you need to set imageView.setOnTouchListener(new ImageMatrixTouchHandler(getApplicationContext())); when resource is ready,

        GlideApp
                .with(this)
                .load(image)
                .thumbnail(0.5f)
                .diskCacheStrategy(DiskCacheStrategy.AUTOMATIC)
                .listener(new RequestListener<Drawable>() {
                    @Override
                    public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Drawable> target, boolean isFirstResource) {
                        return false;
                    }

                    @Override
                    public boolean onResourceReady(Drawable resource, Object model, Target<Drawable> target, DataSource dataSource, boolean isFirstResource) {
                        imageView.setOnTouchListener(new ImageMatrixTouchHandler(getApplicationContext()));

                        return false;
                    }
                })
                .fitCenter()
                .error(R.drawable.no_image)
                .into(imageView);
