My FragmentNewsfeed firebasefragment class.

It seems that your model.thumbnail is returning empty. Check this link, it may help you.

You can do it. Just create an if else statement that if `model.thumbnail.isEmpty()`, then set a default image from your drawable. Else, use the Picasso.load(). – Tepits Aug 02 '18 at 10:02

java.lang.IllegalArgumentException: Path must not be empty.

You can see this error. Your path is empty, you need non empty path: model.thumbnail is an empty string. Picasso loads non empty path. Picasso.with(itemView.context).load(model.thumbnail).into(itemView.NewsThumbnailImageView)

But the link is all set and why did this occur after working for at least a month – Tayyab Ali Aug 02 '18 at 09:29
I think you can show log or debug. I can sure this path is empty. Or can check this link is empty, you show another default image. – RoShan Shan Aug 02 '18 at 09:31
