我与一个非常烦人的问题作斗争。我有一个使用适用于 Android 的 OpenCV 库的应用程序。问题是它抛出了以下异常：

我搜索了解决方案，但没有任何效果。我尝试手动将 libopencv_java.so 添加到 libs/armeabi-v7a 文件夹中，但每次添加时，eclipse 都会自动将其删除。

以下是 mk 文件：

安卓.mk

    LOCAL_PATH := $(call my-dir)

    include $(CLEAR_VARS)

    include  /home/crash-id/Development/SDK/OpenCV-2.4.9-android-sdk/sdk/native/jni/OpenCV.mk

    LOCAL_MODULE := orbdetector
    LOCAL_SRC_FILES := ORBDetector.cpp
    LOCAL_LDLIBS +=  -llog -ldl


include $(BUILD_SHARED_LIBRARY)

应用程序.mk

APP_STL := gnustl_static
APP_CPPFLAGS := -frtti -fexceptions
APP_ABI := armeabi-v7a
APP_PLATFORM := android-16

您的项目属性 -> Java Build Path -> Libraries 选项卡 -> Android Dependencies 下是否有“opencv library 2.4.X.jar”文件？也许尝试删除 Project Properties > Android > Library 下的库（如果您已标记），然后添加我之前提到的 jar 文件。
