Answer 1

ksoap2-android-assembly-2.6.2-jar-with-dependencies.jar

to be put under /libs folder so Eclipse ADT automatically adds your jars to the buildpath of your application.

Download ksoap. jar. Put it under libs folder. Right click on project. Goto properties. Goto java build path. CLick add jars. Add the ksaop jar file to your project from the lib folder.

Clean and build the project. This should help you.

Edit1

Right click "project" -> Properties -> Java Build Path -> Order And Export

Now, make sure that, you have "Checked" that external added "jar" file as you can see in the snap. Make sure that order of that external jar file also same like displayed in snap.
