团队冲刺第四天

今天继续完成索引卡二，已完成。

因为腾讯的开放平台还在审核中，所以我决定加入短信验证。先展示一下结果：

完成这个功能主要是用了MobTech提供的SMSSDK,非常实用，按照官网提供的文档就可以操作。

遇到的问题：

这个问题我去百度说是什么握手失败，所以我判断是联网的部分出了问题，于是一段一段地调试，发现没问题，就很奇怪，恼火。

解决方法：离开电脑，过一会儿重新看，我就发现了问题，一个非常简单的问题，我的Activity没有和layout对应。。。。。

总结：这是我冲刺以来第一次稍微有点崩溃，之前都是问题慢慢解决，这次是不知道错在哪，找不到错，所以有点崩溃。解决方法是如果冷静不下来就先远离电脑，过一段时间再去看之前的代码。
