ksoap2-android eclipse import

I added the library like how google explained here. If i debugg throug the app in the emulator i get the error: "The source attachment does not contain the source for the file SoapObject.class." Whats tha开发者_Go百科t? If i click Change Attached Source i can chose the .jar file again...and the error is not fixed.

in the jar there's no source code, so you can't actually go through those code lines when debugging, like it happens when you're executing your own code. it's just normal.
