Android multidex, UnsatisfiedLinkError - couldn't find .so file

Issue

i'm trying to add some lib (.jar & .so)to my multidex project in android studio.

when i add only a few jars to the project everything works fine. in case i add more and more jars (other libs) i'm getting this error:

java.lang.UnsatisfiedLinkError:
  dalvik.system.PathClassLoader[DexPathList[[zip file
  "/data/app/com.test.digital.ocrtest-2/base.apk"],nativeLibraryDirectories=[/data/app/com.test.digital.ocrtest-2/lib/arm,
  /data/app/com.test.digital.ocrtest-2/base.apk!/lib/armeabi-v7a,
  /vendor/lib, /system/lib]]] couldn't find
  "libScanovatePassportAndIDLSDK_CPP.so"

any idea how can I tell to the compiler to generate jar and so in same dex?

Solution

If some of the extra JARs bring native libraries for armeabi-v7a, while your libScanovatePassportAndIDLSDK_CPP.so was only built for armeabi, the installer will extract a wrong set of libraries. The fix is not to add more copies of .so, but rather strip away the other ABIs. In gradle, you can use splits.
