Could'nt load images from Firestore with Picasso in Android recyclerview

Question

I'm trying to load images stored in my Firestore storage to the image view with RecyclerView of Android. Uploading image is not a problem and I configured same permission for upload and download. But it only shows an image specified in the parameter of placeholder.

I searched several things which seem to be relevant with this issue. Then I found that the matter of the version of Picasso Library and change of with(context) to get().

I applied them to my code and tested.

with the version of Picasso for 2.5.2 then tried with(mContext). Next I tried the version of Picasso for 2.71828 then tried get().

But both gives same result which can be confirmed here.

It seems to be this is not a matter of Picasso. But I couldn't find proper solution.

Anyone can help this out?

Source for onBindViewHolder in an imageAdapter.java

@Override
public void onBindViewHolder(ImageViewHolder holder, int position) {
    Upload uploadCurrent = mUploads.get(position);
    holder.textViewName.setText(uploadCurrent.getName());
    Picasso.with(mContext)
            .load(uploadCurrent.getImageUrl())
            .placeholder(R.mipmap.ic_launcher)
            .fit()
            .centerCrop()
            .into(holder.imageView);

}

As I mentioned above, get() replaced of with(mContext) already tried.

Please let me know if you need further information for this.

Answer 1

you can use a callback to get success/error events.

Picasso.with(mContext)
.load(uploadCurrent.getImageUrl())
.error(R.drawable.error_image)
.into(holder.imageView, new com.squareup.picasso.Callback() {
                    @Override
                    public void onSuccess() {
                       // will load image 
                    }

                    @Override
                    public void onError() {
                       // will not load image from url
                    }
                });
