cocos2dx 使用jni方法获取android mac地址

网上搜索了一下获取android mac地址的方法。这里使用了andriod API的方法 WifiManager

AndroidManifest.xml 添加：

         "android.permission.ACCESS_WIFI_STATE"         >                         
                                  //根据Wifi信息获取本地Mac     public static String getLocalMacAddressFromWifiInfo(Context context){         WifiManager wifi = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);           WifiInfo info = wifi.getConnectionInfo();           return info.getMacAddress();      }

Xcode 代码：

#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID )#include #include <../libs/cocos2dx/platform/android/jni/JniHelper.h>#include #elif (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)#include  // Per msqr#include #include #include #endif

CCString *  HelloWorld:: getMacID(){ #if( CC_TARGET_PLATFORM ==CC_PLATFORM_ANDROID)        JniMethodInfo methodInfo; //用于获取函数体        bool flag = JniHelper::getStaticMethodInfo(                                               methodInfo,                                               "com/cwa/jniTestAndroid/jniTestAndroid",                                               "getAvtivity"  ,                                               "()Ljava/lang/Object;"                                               );    jobject jobj;    int num=10;    if(flag)    {        jobj = methodInfo.env->CallStaticObjectMethod(methodInfo.classID,methodInfo.methodID );    }else    {        CCLog("获取方法Activity失败");    }         flag = JniHelper::getMethodInfo(                                               methodInfo,                                               "com/cwa/jniTestAndroid/jniTestAndroid",                                               "getAndroidMacID",                                               "()Ljava/lang/String;");        jstring jstr;        if(flag)    {        jstr = (jstring) methodInfo.env->CallObjectMethod(jobj,methodInfo.methodID );        std::string str = JniHelper::jstring2string(jstr);        CCLog(" jni 调用结束  str=%s",str.c_str());        return  CCString::create(str.c_str());    }else    {        CCLog(" 获取方法getAndroidMacID失败");            }        return NULL;   #endif}

android代码：

public static Activity instance;protected void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);instance = this;}

    public static Object getAvtivity()    {    return instance;    }    public  String getAndroidMacID()    {    String str = null;        WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);          WifiInfo info = wifi.getConnectionInfo();          str = info.getMacAddress();             if(str==null)        {        Log.e("获取android mac地址失败", "0000000");        }        Log.e("获取android mac地址 "+str, "00000000");    return str;        }
