Question

最近我开始研究 OpenCV 项目，所以关于这一切的一切对我来说都是新的。我下载了opencv 2.4.11，将其作为模块导入到项目中，添加了模块依赖，将所有libs floder从我的解压缩的opencv目录（.. \ OpenCV-android-sdk \ sdk \ native \ libs）复制到src / main / jniLibs文件夹

当我运行应用程序时，它要求nonfree.so所以我下载了这个文件并添加到jniLibs / armeabi-v7a文件夹但是在libnonfree.so文件被自动删除之后。请帮我解决一下这个。在此先感谢！

Android.mk文件

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on
include ..\..\OpenCV-android-sdk\sdk\native\jni\OpenCV.mk
LOCAL_CFLAGS := -DOPEL_ES_1 -DANDROID_NDK
LOCAL_ARM_MODE := arm
LOCAL_C_INCLUDES += $(LOCAL_PATH)
LOCAL_C_INCLUDES += $(LOCAL_PATH)/ObjRecog 
LOCAL_MODULE    := cvgl
LOCAL_SRC_FILES := ObjRecog/commonCvFunctions.cpp ObjRecog/orException.cpp ObjRecog/imageDB.cpp ObjRecog/visualWords.cpp ObjRecog/controlOR.cpp   register_natives.cpp native_main.cpp 
LOCAL_LDLIBS +=  -L$(LOCAL_PATH)/lib -lGLESv1_CM -llog -ldl -lnonfree
include $(BUILD_SHARED_LIBRARY)

gradle这个

sourceSets.main {
    jni.srcDirs = []
    jniLibs.srcDir 'src/main/jniLibs'
}

task ndkBuild(type: Exec, description: 'Compile JNI source via NDK') {
    def ndkDir = android.ndkDirectory
    commandLine "$ndkDir/ndk-build.cmd",
            'NDK_PROJECT_PATH=build/intermediates/ndk',
            'NDK_LIBS_OUT=src/main/jniLibs',
            'APP_BUILD_SCRIPT=src/main/jni/Android.mk',
            'NDK_APPLICATION_MK=src/main/jni/Application.mk'
}
tasks.withType(JavaCompile) {
    compileTask -> compileTask.dependsOn ndkBuild
}
//end

CVGLActivity.class 的System.loadLibrary（ “非自由”）; //第56行

当我在android studio上运行应用程序时，libnonfree.so文件自动被删除
