说明

首先在cocos上构建项目，原生平台上的代码写在项目\build\jsb-link\frameworks\runtime-src\proj.android-studio\app\src\org\cocos2dx\javascript\AppActivity.java中。jsb.reflection.callStaticMethod是cocos调用原生平台的方法，第一个参数可以理解为文件地址，可以根据需求改变，第二个参数是方法名，也可改变，第三个参数是方法的参数类型，()Ljava/lang/String;代表的是这个方法不需要参数，返回string类型的参数。有需要的话可以参考其他文章去改变。

代码

获取当前手机系统版本（安卓版本）

jsb.reflection.callStaticMethod("org/cocos2dx/javascript/AppActivity", "getSystemVersion", "()Ljava/lang/String;");

原生平台代码

public static String getSystemVersion() {
        return android.os.Build.VERSION.RELEASE;
    }

获取手机型号

jsb.reflection.callStaticMethod("org/cocos2dx/javascript/AppActivity", "getSystemModel", "()Ljava/lang/String;");

原生平台代码

public static String getSystemModel() {
        return android.os.Build.MODEL;
    }

获取手机厂商

jsb.reflection.callStaticMethod("org/cocos2dx/javascript/AppActivity", "getDeviceBrand", "()Ljava/lang/String;");

原生平台代码

public static String getDeviceBrand() {
        return android.os.Build.BRAND;
    }

获取手机语言

jsb.reflection.callStaticMethod("org/cocos2dx/javascript/AppActivity", "getLanguage", "()Ljava/lang/String;");

原生平台代码

public static String getLanguage(){
        return Locale.getDefault().toString();
    }

获取手机AndroidID

jsb.reflection.callStaticMethod("org/cocos2dx/javascript/AppActivity", "getAndroidId", "()Ljava/lang/String;");

原生平台代码

这里的getContentResolver方法是非静态的，不能直接写在静态方法里，我的处理方法是在AppActivity.java的onCreate方法中先获取到androidId，再去读取。

	//代码写在AppActivity.java中 定义androidId
	private static String androidId= "";
	//代码写在AppActivity.java的onCreate方法中
	androidId = Settings.System.getString(context.getContentResolver(), Settings.Secure.ANDROID_ID);
	//正常写在AppActivity.java中
	public static String getAndroidId(){
        return androidId;
    }

获取项目包名

jsb.reflection.callStaticMethod("org/cocos2dx/javascript/AppActivity", "getAppId", "()Ljava/lang/String;");

原生平台代码

这里的getApplicationInfo方法是非静态的，不能直接写在静态方法里，我的处理方法是在AppActivity.java的onCreate方法中先获取到appId，再去读取。

	//代码写在AppActivity.java中 定义appId
	private static String appId = "";
	//代码写在AppActivity.java的onCreate方法中
	appId = context.getApplicationInfo().processName;
	//正常写在AppActivity.java中
	public static String getAppId(){
        return appId;
    }

获取手机ip地址

jsb.reflection.callStaticMethod("org/cocos2dx/javascript/AppActivity", "getIP", "()Ljava/lang/String;");

原生平台代码

	//代码写在AppActivity.java中 定义ipAddress
	private static String ipAddress = "";
	//代码写在AppActivity.java的onCreate方法中
	ipAddress = this.getIpAddress(this);
	//正常写在AppActivity.java中
	public static String getIP(){
        return ipAddress;
    }

    public String getIpAddress(Context context) {
        String ip = "";
        ConnectivityManager conMann = (ConnectivityManager)
        context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo mobileNetworkInfo = conMann.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
        NetworkInfo wifiNetworkInfo = conMann.getNetworkInfo(ConnectivityManager.TYPE_WIFI);

        if (mobileNetworkInfo.isConnected()) {//如果不是wifi网络
            ip = this.getLocalIpAddress();
        }else if(wifiNetworkInfo.isConnected()) //如果是WiFi网络
        {
            WifiManager wifiManager = (WifiManager) context.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
            WifiInfo wifiInfo = wifiManager.getConnectionInfo();
            int ipAddress = wifiInfo.getIpAddress();
            ip = intToIp(ipAddress);
        }
        return ip;
    }

    public String getLocalIpAddress() {
        try {
            Pattern ptipv4 = Pattern.compile("^(\\d|[1-9]\\d|1\\d{2}|2[0-4]\\d|25[0-5])(\\.(\\d|[1-9]\\d|1\\d{2}|2[0-4]\\d|25[0-5])){3}$");
            String ipv4;
            ArrayList<NetworkInterface> nilist = Collections.list(NetworkInterface.getNetworkInterfaces());
            for (NetworkInterface ni: nilist)
            {
                ArrayList<InetAddress>  ialist = Collections.list(ni.getInetAddresses());
                for (InetAddress address: ialist){
                    if (!address.isLoopbackAddress() && ptipv4.matcher(ipv4=address.getHostAddress()).matches())
                    {
                        return ipv4;
                    }
                }

            }

        } catch (SocketException ex) {
            Log.e("localip", ex.toString());
        }
        return null;
    }

    public static String intToIp(int ipInt) {
        StringBuilder sb = new StringBuilder();
        sb.append(ipInt & 0xFF).append(".");
        sb.append((ipInt >> 8) & 0xFF).append(".");
        sb.append((ipInt >> 16) & 0xFF).append(".");
        sb.append((ipInt >> 24) & 0xFF);
        return sb.toString();
    }
