回答1:
Change your library file names to "/libs" and check it.
回答2:
Starting with ADT version 17 I believe, Android dependencies are automatically gathered from the libs folder in the root of your project. Try moving your SOAP library to that folder and cleaning your project.
回答3:
I have encountered the same issue .... go to Build Path >> Configure Build Path >> Order and export >> Select KSOAP2 lib . (I am assuming that u have add KSOAP2 Jar)
回答4:
it seems like you forgot to add the external JAR file.
try right clicking you project folder, going to build path and adding the JAR file to the project.
回答5:
Create a directory named libs in your project
Now copy & paste your .jar file into libs directory.
Right click on project build path to add library
select from libs directory & ok
Run -> Success Enjoy
