I'm making this app that has an activity that enables user to log in, the program check´s the information against a database and then sends the user to the dashboard screen. It has been working perfectly but now I'm getting some strange errors that i can't make out where they're coming from.

Here's the logcat:

I think you can not have a URL with underscore, try removing it. See the accepted answer to this post: Target host must not be null, or set in parameters

  • Changed the name of folder of my api files to "androidlogin" and updated it in my android code, but I'm getting the same error. – Erik Soderstrom Jan 18 '13 at 15:06

as in log :

IllegalStateException: Target host must not be null, or set in parameters

means you have not added a protocol(http or https) to the URL. try after to change URL as :

String yoururl="http://xxx.xxx.x.x";
