发送手机验证码

遇到困难：并没有找到在客户端直接发送验证码到邮箱的代码  

    解决困难：之前没有找到免费发送手机验证码的接口，所以打算用邮箱发送验证码，后来有个同学告诉我用mob可以免费发送短信，于是改成发送短信验证码。
          步骤：
          1. 第一步当然是注册账号
          2. 点击 进入后台→选择 SecurityCodeSDK→点击 立即使用→选择应用的平台→获取App key和App Secret
          3. 下载sdk，解压后是这样的：

                                     

 

       4. 之后安装官网导入sdk[官网链接]http://wiki.mob.com/android-%E7%9F%AD%E4%BF%A1sdk%E9%9B%86%E6%88%90%E6%96%87%E6%A1%A3/
       5. 配置好后，添加权限
       6. 我这里是自定义界面，当然也可以使用系统自带界面。代码调用：

//初始化SMSSDK
    private void initSDK()
    {
        SMSSDK.initSDK(forgetPassword.this, "18e3768f516a3", "e05f202526cd41dcf17d2498d6a7aeeb");
        EventHandler eventHandler = new EventHandler() {
            @Override
            public void afterEvent(int event, int result, Object data) {
                Message msg = new Message();
                msg.arg1 = event;
                msg.arg2 = result;
                msg.obj = data;
                msg.what = SMSDDK_HANDLER;
                handler.sendMessage(msg);
            }
        };
        // 注册回调监听接口
        SMSSDK.registerEventHandler(eventHandler);
    }

 getNumber.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                userPhone = phoneNumber.getText().toString();
                new AlertDialog.Builder(forgetPassword.this)
                        .setTitle("发送短信")
                        .setMessage("我们将把验证码发送到以下号码:\n" + "+86:" + userPhone)
                        .setPositiveButton("确定", new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int which) {
                                SMSSDK.getVerificationCode("86", userPhone);
                                getNumber.setClickable(false);
                                new Thread(new Runnable() {

                                            handler.sendEmptyMessage(CODE_ING);
