ContentProvider Add contacts and get contacts to Contacts

In Android, you can use Contentresolver to add, delete, modify, and query the data in a communication record.

Add the following two permissions when you work with a contact

<!--add permissions to an action contact--
<uses-permission android:name= "Android.permission.READ_CONTACTS"/>
<uses-permission android:name= "Android.permission.WRITE_CONTACTS"/>
<!--contact-related URIs--
The data for the content://com.android.contacts/contacts operation is the contact information URI.
Content://com.android.contacts/data/phones Contact Phone URI
Content://com.android.contacts/data/emails Contact Person Email Uri
