Then inside the Driver a JNI (Java Native Interface) is used to call the USBManager using the injected JVM-pointer. As the Driver needs to be implemented in C++, a pointer to the current JVM-instance needs to be injected through the Vuforia Engine stack into the Driver using the userData pointer passed in with the Vuforia::setExternalProviderLibrary() call. The UVC Camera Driver uses the Java-based Android USBManager API to access camera data. The current supported cameras profiles are: The UVCCamera library that this sample uses have implemented the device handle injection. So Android's USBManager is needed to obtain a device handle and then inject it into libusb through libuvc. Unmodified versions of libuvc and libub do not work directly on Android because the USB-device handles can't be obtained in the same way as on a standard desktop Linux-system. This library uses modified versions of libusb and libuvc to handle the USB-cameras. The sample plugin uses an open source UVCCamera library to access camera frame data from USB-cameras.
