Picasso cache returning transformed image instead of original

Question

I am using Picasso for my Android app. Using Picasso transforms i rendered the images transformed in some sections of my app, but when i try to render the image in another part, I get the transformed image as well. How can i get the original image to display it without transformation?

Here is a code example.

String imageUrl = "http://path/image.png";

CustomTransformation *trans= new CustomTransformation();
Picasso.with(this).load(imageUrl).transform(trans).into(myImageView1);
Picasso.with(this).load(imageUrl).into(myImageView2);

After this the two image views are displaying the image with the transformation applied to both of them

Probably you don't set the transformation key so the caching mechanism doesn't see the difference. Example:

private Transformation blur = new Transformation() {
    @Override
    public Bitmap transform(Bitmap source) {
        Bitmap blurred = BitmapUtils.createBlurredBitmap(source);
        source.recycle();
        return blurred;
    }

    @Override
    public String key() {
        return "blurred";   //this will be added to the key that Picasso uses for caching
    }
};
//key: <uri>\nblurred
void loadAndBlur(Uri uri, ImageView mPhoto) {
        picasso.load(uri).transform(blur).into(mPhoto);
}
//key: <uri>
void load(Uri uri, ImageView mPhoto) {
        picasso.load(uri).into(mPhoto);
}
