Android using ION with PhotoView Library

Question

My application keeps crashing every time I try to use the PhotoViewAttacher on my application of the PhotoView library. I'm using ION to display images and trying to get the PhotoView library to allow me to zoom into them. My code currently is:

public class massiveImageView extends Activity {
    ImageView mImageView;
     PhotoViewAttacher mAttacher;
    Drawable drawable;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.massive_image_view);

        // Any implementation of ImageView can be used!
        mImageView = (ImageView) findViewById(R.id.imageViewMassivePage);



        Ion.with(this).load("https://pbs.twimg.com/profile_images/522909800191901697/FHCGSQg0.png").withBitmap().asBitmap()
                .setCallback(new FutureCallback<Bitmap>() {
                    @Override
                    public void onCompleted(Exception e, Bitmap result) {
                        // do something with your bitmap
                        drawable=new BitmapDrawable(result);
                        mImageView.setImageDrawable(drawable);
                    }
                });

                mAttacher = new PhotoViewAttacher(mImageView);

    }
}

And the error I'm getting is at this line:

mAttacher = new PhotoViewAttacher(mImageView);

Saying:

 java.lang.NoClassDefFoundError: uk.co.senab.photoview.PhotoViewAttacher

Any help would be hugely appreciated.

I still don't quite understand why it doesn't work, but I was able to find an answer, where instead of adding the dependency of the library, I just found the jar file online and added that instead, now everything is working perfect. Library Link
