I download the Android SDK from this URL (https://developer.vuforia.com/downloads/sdk). The extracted file doesn't have the JNI folder or .cpp files.
I changed the Teapot 3D image with our own custom 2D images[TextPlane]. Next I need to implement the click on rendering 2D images. When we are searching this requirement on Vuforia site I understand that the click functions are handled inside the .cpp files.
The Android-sdk file contains the Vuforia.jar files and libVuforia.so only. From I will get the JNI folder/.cpp files
Please share your thoughts.
