I'm trying to link the EMDK framework to an existing application and running into linker issues when the application runs. I've been following the basic steps from the 'Import EMDK lib JAR as a Module' section on this page: https://developer.motorolasolutions.com/community/android/android-forums/android-blogs/blog/2015/02/10/developing-emdk-apps-with-android-studio-10x
* I created a new application in Android Studio with a default activity
* Added the com.symbol.emdk.jar library to the libs folder
* Updated AndroidManifest.xml to include <uses-permission android:name="com.symbol.emdk.permission.EMDK" /> and <uses-library android:name="com.symbol.emdk" />
* Added code to the main activity to access the EMDKManager and attach a listener
The project compiles and deploys to a device, but when I run it fails with:

The device runtime is deployed on the handheld (TC55), the samples applications from the EMDK work. Ultimately we need this to work using the Cordova command line build tools, which is why I'm trying to link to the library directly and not rely on the Android Studio-specific runtime configuration.
I've pushed the project files here https://github.com/MattKunze/EmdkLink as well
