OpenCV sample not working on Moto Droid

[TDylse]

I am trying to run your OpenCV sample on a Moto Droid. I am having issues with the native findContours function. When this function is called, the app crashes. When the crash happens the log says:

I also tried creating a separate project and call the findContours function, and I get a No JNI_onLoad found.

I don't know about the first error, but concerning a new project, you're probably getting a JNI linking error because you haven't provided the OpenCV library. Make sure that the System.loadLibrary("opencv") call can find the library. (For reference, JNI_OnLoad() can be found in jni.h:164.)

Does the VideoEmulation project work in the emulator?

It looks like a segmentation fault. See https://github.com/billmccord/OpenCV-Android/issues#issue/7 for the modification of your code, which may be helpful to you.

Can you confirm if the resolutions in Issue 7 solved your problem?
