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.

That's happening because most probably you're loading a wrong image url with picasso — Mr. Patel, Sep 07 '19 at 06:56
What's the value of `uploadCurrent.getImageUrl()`? Please also responde with @AlexMamo — Alex Mamo, Sep 07 '19 at 09:00
When I checked the value of getImageUrl(), it is same with values in a value of Firebase realtime database. But I'm not sure it is same with the URL for image in a Firebase Storage. — pe.jeon, Sep 07 '19 at 12:52

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
                    }
                });

I tried it according to your suggestion. Then I got a result that the all images are changed the error_image. I checked the URL from uploadCurrent.getImageUrl(), it indicates correct URLs of firebase database. – pe.jeon Sep 07 '19 at 12:47
is that url loading properly in browser?.if yes then try to check your internet connection,or if your image size is too large then try too resize in picasso like .resize(200, 200); – Ankit Sep 07 '19 at 12:56
No, actually not. "com.google.android.gms.tasks.zzu@9bdfc92" this is one of urls in my database. But it looks not a proper url for the images. – pe.jeon Sep 07 '19 at 13:02

im soryy for to much late but this is 100% worked fo me.. you just use imagPath in picaso to load image and done

String imagpath="";

 FirebaseStorage storageReference = FirebaseStorage.getInstance();

        DatabaseReference mDatabase = null;
        UploadTask uploadTask;
        StorageReference riversRef = storageReference.getReference();
        final StorageReference imagesRef = riversRef.child("images/Avatars/"+getSaltString()+filePathh.getLastPathSegment());
        uploadTask = imagesRef.putFile(filePathh);

// Register observers to listen for when the download is done or if it fails
        uploadTask.addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception exception) {
                // Handle unsuccessful uploads
            }
        }).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                // taskSnapshot.getMetadata() contains file metadata such as size, content-type, etc.
                // ...
                imagesRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
                    @Override
                    public void onSuccess(Uri uri) {
                        String content = uri.toString();
                        String result = content.substring(content.indexOf("%") + 1, content.indexOf("?"));
                        result = result.substring(2);
                        if (content.length() > 0) {

                            imagepath=content;

                        }
                    }
                });



                //update session image path


            }
        });
