Thanks,

I just found the sample(under samples-advanced-android). But  I can not build the sample. It gives me every time the Error = 

``  Android NDK: ERROR:/home/ImageTargetsNative-5-5-9/app/src/main/jni/Android.mk:Vuforia-prebuilt: LOCAL_SRC_FILES points to a missing file  ```

and after that it comes Error:(45) *** Android NDK: Aborting    .  Stop.

Do you have any idea how to solve that problem ??

Hello,

There is one sample, called ImageTargetsNative, which uses NDK. Normally, the Android Studio Project (the "build.gradle" file) is configured to automatically run the NDK build. However, you can also execute the same step manually via ndk-build from the console in the jni folder of the sample.

Thanks.
