Question

我的应用程序有一个本机部分，可以调用本机Opencv的Camera库。

我唯一的问题是NDK-build不会自动将必要的libnative_camera * * .so复制到libs文件夹中。

每次我对JNI的代码进行更改时（每分钟大约需要3次），我必须手动复制它们，这很好但很烦人。

只有native_camera库才会发生这种情况，opencv_java会自动复制。

这是我的Android.mk：

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
OPENCV_INSTALL_MODULES:=on
OPENCV_CAMERA_MODULES:=on
OPENCV_LIB_TYPE:=SHARED


OPENCV_PATH := /home/tran/signs/OpenCV-2.4.5-android-sdk/sdk/native

include $(OPENCV_PATH)/jni/OpenCV.mk
LOCAL_SRC_FILES  := cameramodule.cpp
LOCAL_C_INCLUDES += $(LOCAL_PATH)
LOCAL_LDLIBS     += -lGLESv1_CM -ldl -llog
LOCAL_MODULE     := cameramodule
include $(BUILD_SHARED_LIBRARY)

如何更改它以告诉NDK-build为我复制和粘贴？

更新

我使用Eclipse编译我的应用程序。这是项目的结构：

PROJECT
   |
   |
   |---src
   |---gen
   |---res
   |---jni
   |---libs
   |---lib (Someone suggest this folder but I can see it has no use)
   |... files and temporary folders

将构建共享库移至Android.mk的顶部：

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES  := cameramodule.cpp
LOCAL_C_INCLUDES += $(LOCAL_PATH)
LOCAL_LDLIBS     += -lGLESv1_CM -ldl -llog
LOCAL_MODULE     := cameramodule
include $(BUILD_SHARED_LIBRARY)

OPENCV_INSTALL_MODULES:=on
OPENCV_CAMERA_MODULES:=on
OPENCV_LIB_TYPE:=SHARED

OPENCV_PATH := /home/tran/signs/OpenCV-2.4.5-android-sdk/sdk/native
include $(OPENCV_PATH)/jni/OpenCV.mk

Answer 2

尝试使用NDK_APP_OUT并将其指向您希望该库驻留的任何目录。

Android NDK构建不会将共享库安装到libs
