[SOLVED] Picasso doesn't tolerate empty String URL?

Picasso doesn't tolerate empty String URL?

I have a viewHolder that loads up an image using Picasso. The DB will return a path of URL as String. So I have my code as below (Using Kotlin)

  Picasso.with(context).load(url).error(placeholder).transform(transformation)
            .placeholder(placeholder).into(this)

It loads fine. However, sometimes the URL is empty. I'm expecting it to load the placeholder instead. But it crash out as below

java.lang.IllegalArgumentException: Path must not be empty.
    at com.squareup.picasso.Picasso.load(Picasso.java:297)

This would force me to explicitly do a check, which is not ideal

if (url == null || url.isEmpty()) {
    Picasso.with(context).load(placeholder).transform(transformation).into(this)
} else {
    Picasso.with(context).load(url).error(placeholder).transform(transformation)
            .placeholder(placeholder).into(this)
}

Is this expected that Picasso will crash when a URL String is empty instead of loading the placeholder?

Solution

The javadoc for Picasso.load() explicitly states that it will throw an IllegalArgumentException when the URL is null or empty. So that's what you can expect.
