Pass Data from Java File to cpp

Question

I am trying to create object detection algorithm in java from the sample code here . However in the code the image value is hardcoded.Is there way i can pass the image location on my own.

   const char * imgInFile = "/sdcard/nonfree/img1.jpg";// Need to pass custom values
const char * imgOutFile = "/sdcard/nonfree/img1_result.jpg";

Thank You

would be replaced with String or byte[] or char[] and note that each char in java takes 2 bytes :) — user2889419

Sure, in Java use

private String imgInFile;
private String imgOutFile;

Then either read these values from an input file, or get them from arguments passed to you application when you run it.

You can add a string parameter to runDemo method. You should change method signature in java and fix jni method prototype in nonfree_jni.cpp file and... Goolge how to pass string to jni.
