 public  String getContactNameByPhoneNumber(Context context, String number) {          String[] projection = { ContactsContract.PhoneLookup.DISPLAY_NAME,                   ContactsContract.CommonDataKinds.Phone.NUMBER };              Cursor cursor = context.getContentResolver().query(                   ContactsContract.CommonDataKinds.Phone.CONTENT_URI, projection, ContactsContract.CommonDataKinds.Phone.NUMBER + " = '" + number + "'", null,null);            if (cursor == null) {               return null;           }           for (int i = 0; i < cursor.getCount(); i++) {               cursor.moveToPosition(i);               int nameFieldColumnIndex = cursor                       .getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME);               String name = cursor.getString(nameFieldColumnIndex);             int contactid=cursor.getColumnIndex(ContactsContract.Contacts._ID);              return name;           }           return null;       }
