将OpenCV Library for Android导入Eclipse后出错

Question

我在Eclipse中导入OpenCV库后遇到了错误。我想我做了我应该做的但也许我错过了一些东西。样本没有错误，但是我的应用程序也有，也有OpenCV Library-2.4.10。

以下是我的输出结果：

Answer 1

从您的错误日志中，您的Android NDK的路径似乎是错误的。您可以通过在Eclipse中指定Android NDK ndk-build的完整路径来更正此问题。

首先，创建一个Build Variable。在Eclipse中，转到Window - ＆gt; Preferences - ＆gt; C/C++ - ＆gt; Build - ＆gt; Build Variables。添加一个引用Android NDK NDK_ROOT文件的完整路径的新变量（您可以将其命名为ndk-build或任何您想要的名称）。

然后，点击Apply并点击Environment（Preferences - ＆gt; C/C++ - ＆gt; Build - ＆gt; Environment）并添加刚刚创建的变量。点击Apply和OK。

然后，右键单击Open-CV-Library，然后选择Properties。导航至C/C++ Build - ＆gt; Environment并在那里添加新创建的变量。点击Apply和OK。

那应该有用。这就是我修理我的方式。

我希望这会有所帮助。

修改

另一个修复可能是使用版本2.4.9而不是版本2.4.10，因为OpenCV网站上的当前说明适用于版本2.4.9。

Answer 2

在我改为OpenCV Library 2.4.9而不是2.4.10后，错误消失了。我使用.mk文件创建了一个jni文件夹后，我的应用程序的错误消失了。
