cocos2dx中的c++文件已经添加到jni里面的Android.mk文件中，但是却依然出现问题，之前有同事修改过这个mk文件，循环读取Classes文件夹中的cpp和c文件，内容如下：
LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) $(call import-add-path,$(LOCAL_PATH)/../../cocos2d) $(call import-add-path,$(LOCAL_PATH)/../../cocos2d/external) $(call import-add-path,$(LOCAL_PATH)/../../cocos2d/cocos) LOCAL_MODULE := cocos2dcpp_shared LOCAL_MODULE_FILENAME := libcocos2dcpp # 配置自己的源文件目录和源文件后缀名 MY_FILES_PATH := $(LOCAL_PATH) \ $(LOCAL_PATH)/../../Classes MY_FILES_SUFFIX := %.cpp %.c # 递归遍历目录下的所有的文件 rwildcard=$(wildcard $1$2) $(foreach d,$(wildcard $1*),$(call rwildcard,$d/,$2)) # 获取相应的源文件 MY_ALL_FILES := $(foreach src_path,$(MY_FILES_PATH),$(src_path),*.*) ) MY_ALL_FILES := $(MY_ALL_FILES:$(MY_CPP_PATH)/./%=$(MY_CPP_PATH)%) MY_SRC_LIST := $(filter $(MY_FILES_SUFFIX),$(MY_ALL_FILES)) MY_SRC_LIST := $(MY_SRC_LIST:$(LOCAL_PATH)/%=%) # 去除字串的重复单词 define uniq = $(eval seen :=) $(foreach _,$1,$(if $(filter $_,${seen}),$(eval seen += $_))) ${seen} endef # 递归遍历获取所有目录 MY_ALL_DIRS := $(dir $(foreach src_path,*/) ) ) MY_ALL_DIRS := $(call uniq,$(MY_ALL_DIRS)) MY_SRC_LIST := $(filter-out %Classes/main.cpp,$(MY_SRC_LIST)) # 赋值给NDK编译系统 LOCAL_SRC_FILES := $(MY_SRC_LIST) LOCAL_C_INCLUDES := $(MY_ALL_DIRS) LOCAL_WHOLE_STATIC_LIBRARIES := cocos2dx_static LOCAL_WHOLE_STATIC_LIBRARIES += cocosdenshion_static LOCAL_WHOLE_STATIC_LIBRARIES += Box2d_static # LOCAL_WHOLE_STATIC_LIBRARIES += cocosbuilder_static # LOCAL_WHOLE_STATIC_LIBRARIES += spine_static # LOCAL_WHOLE_STATIC_LIBRARIES += cocostudio_static LOCAL_WHOLE_STATIC_LIBRARIES += cocos_network_static LOCAL_WHOLE_STATIC_LIBRARIES += cocos_extension_static LOCAL_WHOLE_STATIC_LIBRARIES += cocos2dx-talkingdata include $(BUILD_SHARED_LIBRARY) define add_shared_lib include $(CLEAR_VARS) LOCAL_MODULE := $1 LOCAL_MODULE_FILENAME := $1 LOCAL_SRC_FILES := $(TARGET_ARCH_ABI)/$1.so include $(PREBUILT_SHARED_LIBRARY) endef shared_lib_names := libbdpush_V2_0 \ libBaiduMapSDK_v2_3_1 \ libGif \ liblocSDK4 \ libTeaCrypt $(foreach item,$(shared_lib_names),$(eval $(call add_shared_lib,$(item)))) $(call import-module,.) $(call import-module,audio/android) $(call import-module,Box2D) # $(call import-module,editor-support/cocosbuilder) # $(call import-module,editor-support/spine) # $(call import-module,editor-support/cocostudio) $(call import-module,network) $(call import-module,extensions) #$(call import-module,proj.android/jni)
我为了方便直接添加
<pre name="code" class="html"># 赋值给NDK编译系统 LOCAL_SRC_FILES := $(MY_SRC_LIST) \
<span style="white-space:pre"> </span> $(LOCAL_PATH)/../../ShareSDK/C2DXShareSDK/Android/C2DXShareSDK.cpp \
<span style="white-space:pre"> </span> ...等等
LOCAL_C_INCLUDES := $(MY_ALL_DIRS) \
<pre name="code" class="html"><span style="white-space:pre"> </span> $(LOCAL_PATH)/../../ShareSDK/C2DXShareSDK/Android \
<span style="white-space:pre"> </span> ...等等结果还是无法找到定义C2DXSshareSDK中的各种函数定义，很明显是没有编译该文件，最后改变为
# 赋值给NDK编译系统
<pre name="code" class="html">MY_SRC_LIST += <span style="font-family: Arial,Helvetica,sans-serif;">../../ShareSDK/C2DXShareSDK/Android/C2DXShareSDK.cpp </span>
<pre name="code" class="html"><span style="font-family:Arial,sans-serif;">MY_SRC_LIST += ...等等</span>
<span style="font-family:Arial,sans-serif;"> </span>
<span style="font-family:Arial,sans-serif;"></span><pre name="code" class="html">MY_ALL_DIRS += <span style="font-family: Arial,sans-serif;">$(LOCAL_PATH)/../../ShareSDK/C2DXShareSDK/Android</span>
<pre name="code" class="html">MY_ALL_DIRS += ...等等
LOCAL_SRC_FILES := $(MY_SRC_LIST)LOCAL_C_INCLUDES := $(MY_ALL_DIRS)
还是编译出错，不过错误不同了，显示vector，std找不到，这个时候我把调用他的文件中添加上
include "cocos2d.h" using namespace std; using namespace cocos2d;
好了，编译成功，总结一下android使用ndk只要是c/c++文件出错的，多半编译错误在jni里面的Android.mk文件中。
还有android使用Cocos2dx，记得添加cocos的java的src文件，可以右键选择项目，选择Build Path->Link Source，然后自定义一个名字，把需要的文件夹添加进去，cocos2dx的java目录是...\cocos2d\cocos\platform\android\java\src，当然也可以用其他比如import方式直接选择import->Android->Existing Android Code Into Workspace，选择cocos2dx3.0以上版本直接选择项目中的\cocos文件夹即可。
