The following is a step-by-step tutorial, in which we will build a simple Android application with only one "run demo" button, as is shown in the figure below. We still use SIFT as an example. The main program performing SIFT processing is almost the same as the one in the previous tutorial. I only made some necessary changes for the JNI interface.
