Vuforia on Android

[Przemek Lach]

I have a android binary rule that I've been using to build an Android App that uses the Vuforia SDK ref: https://developer.vuforia.com.

Up to this point I've been using Vuforia 6.x.x with not problems but I need to upgrade to 7.x.x to support newer devices.

Compilation is fine but at run time I'm getting a ClassNotFoundException, specifically:

JNI DETECTED ERROR IN APPLICATION: JNI CallIntMethodV called with pending exception java.lang.ClassNotFoundException: Didn't find class "com.vuforia.ar.pl.Camera2_Preview" on path: DexPathList[[directory "."],nativeLibraryDirectories=[/system/lib, /vendor/lib, /system/lib, /vendor/lib]]

at java.lang.Class dalvik.system.BaseDexClassLoader.findClass(java.lang.String) (BaseDexClassLoader.java:56)

at java.lang.Class java.lang.ClassLoader.loadClass(java.lang.String, boolean) (ClassLoader.java:380)

at java.lang.Class java.lang.ClassLoader.loadClass(java.lang.String) (ClassLoader.java:312)

The com.vuforia.ar.pl.Camera2_Preview is not a new class. It exists in the same spot in 6.x.x as it does in 7.x.x. 

I built a version of my app using Vuforia SDK 6.x.x and 7.x.x and examined the contents of the APK. The files appear the same in both i.e.: no files are missing.

I ran dexdump on classes.dex and searched for Camera2_Preview and got multiple results which means the file is being indexed.

I'm out of ideas on what to do next here. Perhaps indexing is not correct? 

Thanks in advance.

UPDATE

I upgraded from Bazel 0.6.x to 0.10.x but unfortunately problem still persists.
