在Android 4.0中,google已经把移除常用联系人这个功能去掉。

当用户在进行拨打电话，接听电话等电话行为时，系统会自动对其对应号码的使用进行计数。然后根据计数情况来显示常用联系人。 移除常用联系人只是指把该联系人从常用联系人列表移除。

移除常用联系人基本思想是： 在数据库中，保留goolge原来中用对通话进行计数的字段 DataUsageStatColumns.TIMES\_USED  ，新增加一个字段 DataUsageStatColumns.FAKE\_TIMES\_USED 来对通话进行计数，并提供一些对该字段操作接口，然后根据我们 DataUsageStatColumns.FAKE\_TIMES\_USED 计数情况来显示常用联系人

移除常用联系该功能的实现主要分为两个部分：

**第一**， 当用户从Call log删除一个通话记录,表明用户不想和该联系人的该通话记录本看到，因此应该把该联系人从常用联系人列表中移除。

**第二**， 用户可以从常用联系人列表中移除一个联系人，同时把和该联系人相关的Call log记录都删除掉。

添加移除常用联系功能，需要修改两个应用程序的源码，一个是com.android.providers.contacts，另一个是com.android.contacts

。在MTK6575平台上，对于应用 com.android.providers.contacts改动的文件有

packages / providers / ContactsProvider / src / com / android / providers / contacts / CallLogProvider . java

packages / providers / ContactsProvider / src / com / android / providers / contacts / ContactsProvider2 . java

packages / providers / ContactsProvider / src / com / android / providers / contacts / ContactsDatabaseHelper . java

主要修改如下：
