Android Program to Find Contact Details for a Contact Name

Here is source code of the Program to Demonstrate Finding contact details for a contact name. The program is successfully compiled and run on a Windows system using Eclipse Ide. The program output is also shown below.

The following code shows how to use the contact-detail column names available in the CommonDataKinds subclasses to extract the display name and mobile phone number from the Data table for a particular contact.
