I am working on an Android project that uses classes and methods from a seperate JAR file I am also creating, and the issue is with a specific util class called XpathU
When I updata ADT tool to version 18.0.0.v201203301601-306762
I also get the exception when I run the app....
finally i found the solution with adt update issue.
When you build the android app project, you need to go to project Properties-> Order and Export, and let the third party jar checkbox to be checked, and clean and rebuild the project.
The problem would be fixed......for example
