Can any body help me for finding the solution for the same.

String[] projection    = new String[] { ContactsContract.Contacts._ID,
                                        ContactsContract.Contacts.DISPLAY_NAME,
                                        ContactsContract.CommonDataKinds.Phone.NUMBER,
                                        ContactsContract.CommonDataKinds.StructuredPostal.FORMATTED_ADDRESS,
                                        ContactsContract.CommonDataKinds.Photo.PHOTO};
String selection       = ContactsContract.Contacts.HAS_PHONE_NUMBER + " = '1'";
String[] selectionArgs = null;
String sortOrder       = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";

Cursor contacts          = getContentResolver().query(uri, projection, selection, selectionArgs, sortOrder);

Maybe problem will be at selection. Replace yours method with mine.

Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
String[] projection = new String[] { ContactsContract.Contacts._ID,
                                        ContactsContract.Contacts.DISPLAY_NAME,
                                        ContactsContract.CommonDataKinds.Phone.NUMBER,
                                        ContactsContract.CommonDataKinds.StructuredPostal.FORMATTED_ADDRESS,
                                        ContactsContract.CommonDataKinds.Photo.PHOTO};
String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER  + " = ?";
String[] selectionArgs = { String.valueOf(1) }; 
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";

Cursor contacts = getContentResolver().query(uri, projection, selection, selectionArgs, sortOrder);

You should always use parametrized statements. Your approach is dangerous. And your URI was bad.
