Answer 1

Have you added internet permission in Manifest? With Kevin's answer here, Please see the exception log and post the exception here.

Answer 2

In case you want to use Picasso with Kotlin and lambda expression it could be as short as this:

val picasso = Picasso.Builder(context)
            .listener { _, _, e -> e.printStackTrace() }
            .build()

...and then you can load image as usual:

picasso.load(url).into(imageView)

Answer 3

val picasso = Picasso.Builder(context).listener(
                    object : Picasso.Listener{
                        override fun onImageLoadFailed(picasso: Picasso?, uri: Uri?, exception: Exception?) {
                            exception?.printStackTrace()
                            println("Picasso loading failed : ${exception?.message}")
                        }

                    }
            ).build()
picasso.load(imageUrl).into(imageView)

Answer 4

Use builder:

    Picasso.Builder builder = new Picasso.Builder(this);
    builder.listener(new Picasso.Listener()
    {
        @Override
        public void onImageLoadFailed(Picasso picasso, Uri uri, Exception exception)
        {
            exception.printStackTrace();
        }
    });
    builder.build().load(URL).into(imageView);

Edit

For version 2.71828 they have added the exception to the onError callback:

        Picasso.get()
            .load("yoururlhere")
            .into(imageView, new Callback() {
                @Override
                public void onSuccess() {
                }

                @Override
                public void onError(Exception e) {
                }
            })

Answer 5

When you use callback, the picaso will call method onSuccess and onError!

File fileImage = new File(mPathImage);
        Picasso.with(mContext).load(fileImage)
                .placeholder(R.drawable.draw_detailed_view_display)
                .error(R.drawable.draw_detailed_view_display)
                .resize(200, 200)
                .into(holder.mImageEvidence, new Callback() {
                    @Override
                    public void onSuccess() {
                        holder.mMediaEvidencePb.setVisibility(View.GONE);
                    }

                    @Override
                    public void onError() {
                        holder.mErrorImage.setVisibility(View.VISIBLE);
                    }
                });

Answer 6

Please try this to check logs of the Picasso

Picasso.with(getContext()).setLoggingEnabled(true);
