Here is source code of the Program to Set an Activity in Potrait Mode in Andorid. The program is successfully compiled and run on a Windows system using Eclipse Ide. The program output is also shown below.
The Contacts subclass also offers a phone number lookup URI to help find a contact associated with a particular phone number. This query is highly optimized to return fast results for caller-ID notification. Use ContactsContract .PhoneLookup.CONTENT_FILTER_URI, appending the number to look up as an additional path segment.
