<h2>四、Android 个人通讯录功能测试</h2>
<ol>
<li>添加</li>

<h2>五、注意事项</h2>
<p>测试中的一些问题：</p>
<ol>
<li><code>联系人电话号码不能重复添加</code>，程序会终止退出，因为联系人的电话号码是唯一的（一个人可以有多个手机号，而一个手机号只能一个人使用 {该功能程序已经实现} ）。</li>
<li>电话号码<code>长度限制为11位</code>。</li>
<li>联系人<code>信息为空不能成功添加</code>。</li>
</ol>
<pre><code class="prism language-java">再次添加联系人：姓名：小莉电话：<span class="token number">15866655588</span>
