How to resolve java.net.MalformedURLException?

I am getting this error:

java.net.MalformedURLException: Protocol not found[java.lang.StringBuilder]

When the following line is getting executed:

url = new URL(urlString.toString());

urlString stores the following value:

http://maps.google.com/maps?f=d&hl=en&saddr=25.04202,121.534761&daddr=25.05202,121.554761&ie=UTF8&0&om=0&output=kml

What causes this Exception?

Solution

  • Chances are that you didn't clean after changing from 

    url = new URL( urlString );

    to

    url = new URL(urlString.toString());

    You should log the value of the parameter passed to the constructor of URL. It's not what you think it should be.

    urlString would print a value in the form of java.lang.StringBuilder@ thus throwing the exception if you try to build a url out of that.

    But using to String will print the value of the content string built by the stringbuilder.
