Android : findLibrary works on phone but not on Tablet

I'm using the Kofax library in my android project.

The structure of the libs folder is:

jniLibs
-armeabi
--(.so libraries)
-armeabi-v7
--(.so libraries)
(.jar libraries)

my grade build file includes

    task nativeLibsToJar(type: Zip, description: 'create a jar archive of the native libs') {
        destinationDir file("libs")
        baseName 'libs-arm'
        extension 'jar'
        from fileTree(dir: 'libs', include: '**/*.so')
        into 'lib/'
    }

    tasks.withType(JavaCompile) {
        compileTask -> compileTask.dependsOn(nativeLibsToJar)
    }

    dependencies {
        compile fileTree(dir: 'libs', include: '*.jar')
        compile project(':googleplayservices_lib')
    }

 sourceSets { main {  jniLibs.srcDirs = ['libs'] } }

This configuration works fine running on a Samsung Galaxy SIII phone but when I run the application on Samsung Galaxy Tab 10.1, it crashes with the following error:

Caused by: java.lang.UnsatisfiedLinkError: Couldn't load AtalaBar from loader dalvik.system.PathClassLoader[dexPath=/data/app/enbd.mobilebanking-2.apk,libraryPath=/data/app-lib/enbd.mobilebanking-2]: findLibrary returned null

At first I thought it was a processor problem: the libraries I have are for the ARM processor and the tablet uses the Krait processor. However, when I run Koufax's sample application, it works fine. I've compared the gradle file of the sample app and mine and everything is in order.

I can't figure out where the problem is. I'd really appreciate some help. Thanks.
