Question

我使用android ndk独立工具链成功地将 c ++库编译成了android平台。我使用jni dolder和Android.mk文件在Eclipse中创建了一个新的Android应用程序项目，当我进行ndk-build时，构建顺利，并将mylib.so添加到libs / armeabi文件夹问题是当我做一个System.loadLibrary（“mylibname”）; 我在logcat中收到以下错误：无法dlopen（/data/data/com.oussama.firsttry/lib/libdash.so）：无法加载库：link_image [1995]：无法链接libdash.so 导致 java.lang.UnsatisfiedLinkError：我的lib未找到** 。

我的lib必须有一个库，模拟器无法加载它所以我已经完成了 readelf -d mylib.so ，结果如下：

偏移量为0x1617c4的

这是我的Android.mk文件：

 LOCAL_PATH := $(call my-dir)

 include $(CLEAR_VARS) LOCAL_MODULE    := libcurl  LOCAL_SRC_FILES :=
 ../../../../neededLibs/libcurl.a

 include $(PREBUILT_STATIC_LIBRARY)

 include $(CLEAR_VARS) LOCAL_MODULE    := libxml  LOCAL_SRC_FILES :=
 ../../../../neededLibs/libxml2.a

 include $(PREBUILT_STATIC_LIBRARY)

 include $(CLEAR_VARS) LOCAL_MODULE    := libz  LOCAL_SRC_FILES :=
 ../../../../neededLibs/libz.a

 include $(PREBUILT_STATIC_LIBRARY)

 include $(CLEAR_VARS) LOCAL_MODULE    := m  LOCAL_SRC_FILES :=
 libm.so include $(PREBUILT_SHARED_LIBRARY) include $(CLEAR_VARS)
 LOCAL_MODULE    := dl  LOCAL_SRC_FILES := libdl.so

 include $(PREBUILT_SHARED_LIBRARY) include $(CLEAR_VARS) LOCAL_MODULE
 := c  LOCAL_SRC_FILES := libc.so

 include $(PREBUILT_SHARED_LIBRARY)

 include $(CLEAR_VARS)

 LOCAL_MODULE := d LOCAL_SRC_FILES := libdash.so
 LOCAL_SHARED_LIBRARIES := c m dl 

 LOCAL_STATIC_LIBRARIES := libz libxml libcurl  include
 $(PREBUILT_SHARED_LIBRARY)

我现在真的陷入困境，我无法弄清楚丢失的库是什么

当我执行ndk-build V = 1 -B时，我得到以下结果：

如果有人能帮助我，我会感激不尽。

找不到java.lang.unsatisfiedLinkError lib :(无法链接mylib.so）
