修改cocos2d-x 3.3 android mk文件 为 自动遍历*.cpp文件，亲测~~

我们在自己新建的项目中，比如项目Mycpp，在项目Mycpp\proj.android\jni的路径下找到android mk 文件，先来看看这个android.mk文件的内容，打开之后是这样子的，我们没有改过

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

LOCAL_SRC_FILES := hellocpp/main.cpp \
                   ../../Classes/AppDelegate.cpp \
                   ../../Classes/HelloWorldScene.cpp

LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes

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       # 添加 cocostudio 静态库
# LOCAL_WHOLE_STATIC_LIBRARIES += cocos_network_static
# LOCAL_WHOLE_STATIC_LIBRARIES += cocos_extension_static  # 添加 cocos_extension 静态库


include $(BUILD_SHARED_LIBRARY)

$(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) # 导入 cocostudio 模块  
# $(call import-module,network)
# $(call import-module,extensions)   # 导入 extensions 模块

如果我们在自己的cpp项目中有用到这两个库的话，cocostudio，extensions，只需要去掉android.mk文件中的注释号“#”，虽然cocos2dx 的团队已经提醒了我们，只不过在前面加了“#”注释号，就是上面有注释的几行代码，不过还是需要注意的是，如果在cpp项目中要添加头文件的话，需要这样子写，

#include "extensions/cocos-ext.h"

#include "cocostudio/CocoStudio.h

如果写成下面这个的话，win32环境下虽然能编译通过，但是在android环境下是编译不通过的，要注意

#include "cocos-ext.h"

#include "CocoStudio.h

LOCAL_SRC_FILES := hellocpp/main.cpp \
                   ../../Classes/AppDelegate.cpp \
                   ../../Classes/HelloWorldScene.cpp

# 遍历目录及子目录的函数  
define walk  
    $(wildcard $(1)) $(foreach e,$(wildcard $(1)/*),$(call walk,$(e)))  
endef  
  
# 遍历Classes目录  
ALLFILES = $(call walk,$(LOCAL_PATH)/../../Classes)  
                     
FILE_LIST := hellocpp/main.cpp  
# 从所有文件中提取出所有.cpp文件  
FILE_LIST += $(filter %.cpp,$(ALLFILES))  
  
LOCAL_SRC_FILES := $(FILE_LIST:$(LOCAL_PATH)/%=%) 

改完之后完整android mk 文件如下：

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

$(call import-add-path,$(LOCAL_PATH)/../../cocos2d/cocos)

LOCAL_MODULE := cocos2dcpp_shared

LOCAL_MODULE_FILENAME := libcocos2dcpp


# 遍历目录及子目录的函数  
define walk  
    $(wildcard $(1)) $(foreach e,$(ALLFILES))  

  
LOCAL_SRC_FILES := $(FILE_LIST:$(LOCAL_PATH)/%=%)

LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes

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       # 添加 cocostudio 静态库
LOCAL_WHOLE_STATIC_LIBRARIES += cocos_network_static
LOCAL_WHOLE_STATIC_LIBRARIES += cocos_extension_static  # 添加 cocos_extension 静态库


include $(BUILD_SHARED_LIBRARY)

$(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)  # 导入 cocostudio 模块
$(call import-module,network)
$(call import-module,extensions)  # 导入 extensions 模块

Android.mk文件

基本语法：

“#” 注释

“：=” 赋值

“+=” 追加

“$” 引用某变量的值

#宏函数my-dir返回编译系统提供的当前路径，即Android.mk的目录
#如（HelloWorld/proj.android/jni/XX）
LOCAL_PATH := $(call my-dir)


#初始化模块  重置除LOCAL_PATH变量以外的所有变量 
include $(CLEAR_VARS)

#导入库目录
$(call import-add-path,$(LOCAL_PATH)/../../cocos2d/cocos)

#模块名，唯一。
LOCAL_MODULE := cocos2dcpp_shared
#模块文件名，唯一（可选）
LOCAL_MODULE_FILENAME := libcocos2dcpp

#配置头文件的搜索范围
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes
#获取静态库
LOCAL_WHOLE_STATIC_LIBRARIES := cocos2dx_static
#追加静态库
LOCAL_WHOLE_STATIC_LIBRARIES += cocosdenshion_static



#根据编译器提供的变量BUILD_SHARED_LIBRARY生成动态库
include $(BUILD_SHARED_LIBRARY)



#导入模块，以下是常用的几个模块

$(call import-module,audio/android)
$(call import-module,editor-support/cocostudio)
$(call import-module,extensions)
