Thanks dwmccandless for sharing your solution. I have added your notes to the article in here:

To get this to work in Android Studio, I used the following from http://stackoverflow.com/questions/16683775/include-so-library-in-apk-in-android-studio:

I've tried the solution presented in the accepted answer and it did not work for me. I wanted to share what DID work for me as it might help someone else. I've found this solution here.

Basically what you need to do is put your .so files inside a a folder named lib (Note: it is not libsand this is not a mistake). It should be in the same structure it should be in the APK file.

In my case it was:
Project:
|--lib:
|--|--armeabi:
|--|--|--.so files.

So I've made a lib folder and inside it an armeabi folder where I've inserted all the needed .so files. I then zipped the folder into a .zip (the structure inside the zip file is now lib/armeabi/*.so) I renamed the .zip file into armeabi.jar and added the line compile fileTree(dir: 'libs', include: '*.jar') into dependencies {} in the gradle's build file.

This solved my problem in a rather clean way.

https://developer.vuforia.com/forum/android/using-android-studio-vuforia should be updated to include this information or to allow for questions and comments (or both).

Thanks for the help on this. It seems like refreshing Eclipse was the issue I was having.

I actually need to get the example running in Android Studio, so I thought getting it working in Eclipse might help me, but I am still stuck with the following error in Android Studio: The library libVuforia.so could not be loaded

I have manually added libs/armeabi-v7a/libVuforia.so to the Android Studio project. The default import placed the Vuforia.jar file in src/main/java, so I tried moving it to libs/ thinking that might help, but I still get the same error.

The build.gradle file has the following (depending on which copy of the jar I am trying):

libVuforia.so must be located under your project directory, under libs / armeabi-v7a / ... if you already copied there, that should be ok.

However, have you also added Vuforia.jar ? (You need both Vuforia.jar and libVuforia.so, as libVuforia.so is used by the JAR)

to add Vuforia.jar, go to Project > Properties > Java Build Path and add the Vuforia.jar in the Libraries tab. Also, in the Order and Export tab, check Vuforia.jar as well (so that it gets exported and packaged when the apk is built).

Also, make sure to always Refresh Eclipse whenever you make a change in the project settings.

That's good to hear.

However, can you explain how the project works when I run it with the code in the samples directory within vuforia-sdk-android-2-8-8, but when I create a project in a different directory (and manually copy libVuforia.so to libs//armeabi-v7a)  I get the following error: The library libVuforia.so could not be loaded?

libVuforia.so has no specific settings hard-coded... you don't need to rebuild it.  

I had this problem initially even after manually copying libVuforia.so to the appropriate location. I have been able to get this to work by not checking "Copy projects into workspace" in Eclipse. So, it appears that libVuforia.so has something hardcoded. How do I get the project to initialize the Vuforia library appropriately if I want a setup with a project location that is not identical to the examples default location?

Does this require modifying something and rebuilding via NDK?

There is a file CopyVuforiaFiles.xml , change path (<fileset dir="C:/Users/ ..... /build/lib/armeabi-v7a"/>)  where is your  libVuforia.so  file, if this doesnt work for you then you should copy and paste this file to your project  in Android Studio , to folder: libs > armeabi-v7a > libVuforia.so

From windows console, what do you mean by outside Android Studio ?

Have you run the ndk-build from a command line (e.g. cygwin or windows console) ?

The ndk-build compiling should be handled outside of Android Studio.
