java.lang.noclassdeffounderror: org.ksoap2.serialization.SoapObject

Question

I got this no class def error: org.ksoap2.serialization.SoapObject error ever since I have updated Eclipse ADT Plug in and SDK Manager. I was using ksoap2

Answer 1

Go to Properties -> Java Build Path

Add ksoap2-android-assembly-2.6.2-jar-with-dependencies.jar as external jar

Go to the Order and Export tab on the same popup window

Check the box against the newly added jar

(see: NoClassDefFoundError - Eclipse and Android)

Answer 2

What I did:

1. Download ksoap2-android-assembly-2.6.5-jar-with-dependencies, if you see it comes with zip extension. Change it to jar extension.
2. Copy the jar file to libs folder on your project.
3. Rebuild your project.

Answer 3

Turns out external jars such as

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. It was a buildpath missing defined class error after all.. I hope this will help you, too!
