click to edit
enter the actual path to the Vuforia.jar library (which is located under your vuforia_install_dir/build/java/vuforia)
In the Project view, right-click on the Project and expand the view hierarchy so to locate the Vuforia.jar under app > src > main
right-click on Vuforia.jar to open the context menu

right-click on the Project and select "Open Module Settings"
select "App"

Copy the "armeabi-v7a" folder (including the libVuforia.so file located inside it) from the "vuforia_install_dir/build/lib" to the "app/src/main/jniLibs" folder
the resulting directory structure under your project root should be:
/app
/src
/main
/jniLibs
/armeabi-v7a
libVuforia.so
Clean and rebuild the project
Run the app on your device
