It depends on how the library loads the so files. Open SQLCipher.jar with 7zip to see the standard location for so files.

Thank Erel.
The .so file not in the .jar file. when I put in the .so in .jar like SQLCiper.jar,Error still exists.

The SDK provided by the third party,he does'nt tell me how the library loads the so files,but he tell me an example
libs/jcore-android.v1.x.y.jar
libs/jpush-android_v3.x.y.jar
libs/(cpu-type)/libjcore1xy.so

so I put the .so file \Objects\libs ,and made it readonly ,but the same error: Couldn't load jcore110 from loader

Are you sure that it is libs and not lib?

You should put in the jar file in the correct folder. Putting it under Objects folder will not help.

I have tested lib and libs,and all I can find in the forums,but i failed.
I open the .jar with winrar,and add a new folder lib(or libs),and copy .so in it, .jar is in the folder AdditionalLibraries.

the error:java.lang.UnsatisfiedLinkError: Couldn't load jcore110 from loader dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/bjfhs.guo.com-2.apk"],nativeLibraryDirectories=[/data/app-lib/bjfhs.guo.com-2, /system/lib]]]: findLibrary returned null

The SDK document show that you only need copy libjcore110.so to cpu-type folder of project, and all the function your need in the .jar file.

Creating libraries requires Java knowledge. If you aren't able to solve it then you can make a post in the job offers forum.

You need to write a wrapper library (in java) for the third party jar and their .so file, yes.
As already told this requires java-knowledge.

Thank DonManfred and Erel, I will try to write a wrapper.
But why I can't use #AdditionalJar? where and when I can use #AdditionalJar?

#AdditionalJar only adds a reference to the jar file. In order to actually use the library you will still need to understand its API. In your case you also need to find out where the .so file should be located.
