I'm not sure of that. I tried your url with quotes and I got the same exception. — Sotirios Delimanolis

@SotiriosDelimanolis If you hardcode it, it works. It might be something with the string escaping maybe. — Patrick Bassut

@Patrick Right. So escaping characters in Strings is only important for String literals, that is string values hardcoded in the source code. Escape characters are removed (converted to a value) at runtime. The value in the logs is a String in memory. It appears to contain leading and ending quotation marks ". This will cause the URL parser to fail. — Sotirios Delimanolis

@Patrick The String literal (ie. in source code) String url = "\"http:\""; has the String value "http:" at runtime. If your question refers to something like a JSON array ["value1", "value2"], the answer depends on the parser. A proper parser will determine that the elements are JSON Strings and produce two String objects in an array with the values value1 and value2. — Sotirios Delimanolis

I don't know of any logger that will add enclosing quotes to a given log message. As such, I'm going to assume that your url String is literally

"https://s3-sa-east-1.amazonaws.com/inradar.media/uploads/ads/ad-60cd15be59b21725e45c5cf388065527.jpg"

The URL constructor cannot parse that value. Get rid of the leading and trailing quotation marks.
