Runtime error : java.lang.String java.lang.Throwable.toString() on a null object reference



It’s weird that your ExtendedWebViewer1.WebViewer references itself. Are you sure that this is correct?


@Red_Panda i’m new to this platform and also to android development…would you please be more detailed with this problem?
what wrong did i do? and why is this happening…
before it was going alright but now this app just crashes saying runtime error…

thank for your help…its great to have such community.


Well, the ExtendedWebViewer needs a WebViewer as input
