类似OpenCV 2.3：如何从Android的摄像头捕捉帧

我试图让OpenCV的在我的三星着迷（V2.2.1）以下的本教程

I'm trying to get OpenCV to run on my Samsung Fascinate (v2.2.1) following this tutorial

当我尝试运行，例如样品（样15拼图），我收到以下错误：

When I try to run the samples (like sample 15-puzzle) for instance, I get the following errors:

所以库不能被打开。为什么任何想法？难道不是被发现的？

So the library cannot be opened. Any ideas on why? Is it not being found?

更新：这也发生在模拟器上

Update:This also happens on the emulator.

推荐答案

确认 libnative_camera_r2.2.2.so 是库/ 。该文件应当被打包，以便它可以通过的dlopen 动态加载。

Make sure libnative_camera_r2.2.2.so is in libs/. That file should be packaged so that it can be loaded dynamically by dlopen.
