如何包含许多共享库。所以要构建android apk

我想使用tow

extern

库来构建android应用程序，使用surf算法跟踪对象，所以我使用了本教程

第一个库是

libobjtrack\u opencv\u jni.so

（用于跟踪）和另两个库是libopencv\u java.so和

libobjtrack\u opencv\u jni.so

我最终得到了这个结果：

Android.mk:

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE    := sift_prebuilt
LOCAL_SRC_FILES := libnonfree.so
include $(PREBUILT_SHARED_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE    := opencv_java_prebuilt
LOCAL_SRC_FILES := libopencv_java.so
include $(PREBUILT_SHARED_LIBRARY)


include $(CLEAR_VARS)
LOCAL_MODULE    := objtrack_opencv_jni
LOCAL_SRC_FILES := libobjtrack_opencv_jni.so
include $(PREBUILT_SHARED_LIBRARY)
include $(CLEAR_VARS)
OPENCV_LIB_TYPE        := STATIC
OPENCV_INSTALL_MODULES:=on
OPENCV_CAMERA_MODULES:=off
include C:/OpenCV-2.4.5-android-sdk/sdk/native/jni/OpenCV.mk
LOCAL_C_INCLUDES:= C:/OpenCV-2.4.5-android-sdk/sdk/native/jni/include
LOCAL_MODULE    := test_sift12
LOCAL_CFLAGS    := -Werror -O3 -ffast-math
LOCAL_LDLIBS    += -llog -ldl
LOCAL_SHARED_LIBRARIES := sift_prebuilt opencv_java_prebuilt objtrack_opencv_jni
LOCAL_SRC_FILES := test_sift.cpp
include $(BUILD_SHARED_LIBRARY)

构建成功，我得到了

测试\u sift12。因此

但在运行

.apk

时不起作用。。我认为问题在于在

android.mk

文件中使用

prebuild\u SHARED\u LIBRARY

。

我需要您的帮助

加载库，您希望在活动中使用这些库

像这样

public class YourClassName extends Activity {

.....

//add the following code at the end of the class


  static 
  {
      System.loadlibrary("opencv_java");
      System.loadlibrary("objtrack_opencv_jni");
      System.loadlibrary("nonfree");
      System.loadlibrary("test_sift12");
   }
}

我建议你改变你的名字如下

LOCAL_MODULE    := sift_prebuilt

到

及

到

记住不要忘记修改

本地共享库中的名称

LOCAL_MODULE    := nonfree

LOCAL_MODULE    := opencv_java_prebuilt

LOCAL_MODULE    := opencv_java
