在对联系人进行操作时需加入以下两个权限
<!-- 添加操作联系人的权限 -->
<uses-permission android:name="android.permission.READ_CONTACTS" /><uses-permission android:name="android.permission.WRITE_CONTACTS" /><!-- 联系人相关的uri -->content://com.android.contacts/contacts 操作的数据是联系人信息Uricontent://com.android.contacts/data/phones 联系人电话Uricontent://com.android.contacts/data/emails 联系人Email Uri一、清单文件
