Opencv Android：java.lang.UnsatisfiedLinkError：dlopen失败：无法加载库“libopencv_java.so”

概述在邮政底部更新 我试图在Android上使用OpenCV人脸识别器,虽然我能够包装c代码我无法使其在英特尔凌动avd上工作.我不是100％肯定,但我认为标题中错误的原因是我想念/ lib / x86项目目录中的libopencv_java.so. 任何想法为什么缺少lib以及如何让它正常工作？ 我的Android.mk看起来像： LOCAL_PATH := $(call my-dir)incl 在邮政底部更新

我试图在Android上使用OpenCV人脸识别器,虽然我能够包装c代码我无法使其在英特尔凌动avd上工作.我不是100％肯定,但我认为标题中错误的原因是我想念/ lib / x86项目目录中的libopencv_java.so.

任何想法为什么缺少lib以及如何让它正常工作？

我的AndroID.mk看起来像：

LOCAL_PATH := $(call my-dir)include $(CLEAR_VARS)OPENCV_liB_TYPE:=SHAREDinclude /home/fat/ScaricatI/OpenCV-2.4.9-androID-sdk/sdk/native/jnI/OpenCV.mkLOCAL_MODulE    := FaceDetectionPerformancesLOCAL_SRC_fileS := FaceDetectionPerformances.cppfile_List_CPP := $(wildcard $(LOCAL_PATH)/*.cpp) # finds all cpp filesOPENCV_INSTALL_MODulES:=oninclude $(BUILD_SHARED_liBRARY)

虽然我的Application.mk是

APP_STL := gnustl_staticAPP_CPPFLAGS := -frtti -fexceptionsAPP_ABI := x86 armeabi armeabi-v7aAPP_PLATFORM := androID-8

ndk-build日志是

更新1
opencvAndroIDSdk包为x86 arch提供了共享库libopencv_java,但是ndk在构建时不会将它移动到libs / x86目录,而是为armeabi arch.我还尝试将它从/OpenCV-2.4.9-androID-sdk/sdk/native/libs/x86/libopencv_java.so手动移动到/ libs / x86项目子目录,但是当我构建项目时,ndk删除文件.

解决方法 经过一番研究,我设法解决了我的问题.显然APP_PLATFORM androID-8与x86 android-opencv libs不兼容.所以我只针对androID-9并且它有效. 总结
