Answer 1

Change your library file names to "/libs" and check it.

Answer 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.

Answer 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)

Answer 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.

Answer 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
