【问题描述】：
类似于OpenCV 2.3: how to capture frames from Android camera?
我正在尝试让 OpenCV 在我的 Samsung Fascinate (v2.2.1) 上运行 this tutorial
例如，当我尝试运行示例（例如示例 15-puzzle）时，我收到以下错误：

所以图书馆无法打开。关于为什么的任何想法？是不是没找到？
更新：这也发生在模拟器上。
【问题讨论】：
-
我进行了快速搜索，但不确定您的意思。其他 android 应用程序在我的手机上运行良好，它似乎在模拟器上可以找到，但在我的设备上却没有（所以我认为这是一个运行时问题）
-
抱歉，有误会。我的错。删除之前的评论。您的手机和模拟器中有哪个 sdk？他们是一样的吗？您是否执行了以下帖子中的步骤？ link
-
它们都是 2.2。不确定该链接是否适用，因为我的计算机上已经有库。我想知道这是否是一个错误。
