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

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!

java.lang.NoClassDefFoundError: org.ksoap2.serialization.SoapSerializationEnvelope

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

Android ksoap2 library throwing NoClassDefFoundError exception on SoapObject

After spending hours and backtracking code, I finally found the source of bug. It was a dependence issue, and it was happening due to conflict in dependencies. There wasn't any message, log or error pointing in this direction. I removed Glide and it fixed the issue. Now I am using Picasso.

compile 'com.github.bumptech.glide:glide:3.7.0'

kSoap 2 2.6.5 Could not find class 'org.ksoap2.serialization.SoapObject'

Well, to make the solution a bit clear for the next followers:

1. right-click on your project -> property
2. select Java Build Path
3. tab order and export -> check on your jar library file which is KSOAP jar for issue.

Good luck!

Getting error when updating ADT pugin java.lang.NoClassDefFoundError: org.ksoap2.serialization.SoapObject

Create new folder "libs" in the project and copy all the External Jar file files in this folder.then Right Click on Project -> Properties->Java Build Path->Here Change the Path of Jar files to "Libs" folder and remove the path of extrenal jar files that you have given from computer path.After That it will Work.

Note:if there is already folder "lib" in your project then only change the folder name "lib" to "libs".
If you are not getting my point then check this site:

Name of folder Should be "libs" not "Libs"

Error ksoap2 serialization

You need to copy the jar(s) to the libs directory in the project. The ADK picks the libraries from that folder and convert them into classes optimized for Dalvik.

Creating a folder "libs" in the project
Copying the external jars in to the folder
Refresh the folder
Go to properties -> Build path -> Add Jar (not external JAR)
Clean the project
Restart Eclipse

Try this also,

Go to the Order and Export tab on the same popup window
Check the box against the newly added jar

ksoap2 error with android studio

First put your lib into libs folder, then right click it and select "Add as library".
Open build.gradle file and add your library

dependencies {
compile files('libs/android-support-v4.jar')
compile files('libs/ksoap2-android-assembly-3.0.0-RC.4-jar-with-dependencies.jar')
}

Finally go to root folder in a terminal and run "./gralew clean", rebuild and run your android app.
