Android application using SAP JCO to connect to CRM system

[Former Member]

I'm in the mid of developing an android application, which is to connect to SAP CRM system to fetch some data.  I'm using JCO for the same.  When I run it as standalone java application (i.e. not in android platform) I can successfully fetch data.  But when I run the same as android application, I get the following error in log cat:

Caused by: java.lang.ExceptionInInitializerError: JCo initialization failed with java.lang.UnsatisfiedLinkError: Couldn't load sapjco3 from loader dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.example.firstapp-1.apk"],nativeLibraryDirectories=[/data/app-lib/com.example.firstapp-1, /system/lib]]]: findLibrary returned null

I have added the jco library in libs folder of my android project and tried several variations.  The error persists.

Can someone please help ?

Hallo,

that won't work!

JCo requires a native library that is not available for Android platforms.

Maybe someday it will be available.

On windows the JCO jar relies on some external windows DLLs as well to communicate with the backend.  I suspect that is the problem as is it trying to find the DLL library to load and cannot find and load it.

Did you have any success with that question? I think that JCO can't be used in Android OS.

Check your java build path, make sure you have check marked your libraries.
