android - UnsatisfiedLinkError : Couldn't load libopencv_java. 所以

Question

我遇到了一个非常烦人的问题。我有一个使用 Android 版 OpenCV 库的应用程序。问题是它抛出以下异常:

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，但每次添加它时，eclipse 都会自动将其删除。

这是 mk 文件:

Android.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)

Application.mk

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

Answer 1

您的项目属性 -> Java 构建路径 -> 库选项卡 -> Android 依赖项下是否有“opencv 库 2.4.X.jar”文件？也许尝试在 Project Properties > Android > Library 下删除库(如果你有标记的话)，然后添加我之前提到的 jar 文件。
