        null);

how to write where clause here to satisfy my conditions?

Answer 1

add Where clauses with ” AND “.. Pretty simple.. Each condition is seperated by the same..

here is an example

String addrWhere = ContactsContract.Data.CONTACT_ID+" = ? AND "+ContactsContract.Data.MIMETYPE+" = ?"; //this is where clause and below is corresponding selection args..  
String[] addrWhereParams = new String[]{data.getContac_ID(), 
                ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE};
