Android 工具函数汇总 （获得设备唯一 DeviceId）

//返回设备唯一的 id
    public static String J_C_getIosDeviceId()
    {
        String android_id = Secure.getString(getContext().getContentResolver(), Secure.ANDROID_ID);
        return android_id;
    }
    //判断当前是否有可用网络
    public static boolean J_C_isNetworkOK()
    {
        //获取当前的网络连接服务

        try {
            ConnectivityManager connectivity = (ConnectivityManager) getContext().getSystemService(Context.CONNECTIVITY_SERVICE);
            if (connectivity != null) {

                NetworkInfo info = connectivity.getActiveNetworkInfo();
                if (info != null && info.isConnected()) {

                    if (info.getState() == NetworkInfo.State.CONNECTED) {
                        return true;
                    }
                }
            }
        } catch (Exception e) {
            return false;
        }
        return false;

    }

    //打开url
    public static void J_C_toOpenNetworkURL(String url)
    {
         Uri uri = Uri.parse(url);
            Intent it = new Intent(Intent.ACTION_VIEW, uri);
            getContext().startActivity(it);
    }

对应 ios DeviceId 代码参考：

//获得临时的UUID

std::string getIosDeviceId()

{

    std::string m_str;

    NSString* idStr = [OpenUDID value];  //

    m_str = [idStr UTF8String];

    return m_str;

    

}
