You can query your content cursor to see what properties contacts have.

Cursor c1 = appActivity.getContentResolver().query(                      ContactsContract.Data.CONTENT_URI                      ,null,null,null, null); c1.moveToFirst(); DatabaseUtils.dumpCursor(c1); c1.close();

Or specifically if you want to query for whatsapp contacts here are the properties:

You can query for ContactsContract.RawContacts.ACCOUNT_TYPE with value com.whatsapp
You can use MIMETYPE with value vnd.android.cursor.item/vnd.com.whatsapp.profile

Example:

 c = appActivity.getContentResolver().query(              ContactsContract.Data.CONTENT_URI              ,new String[] { ContactsContract.Contacts.Data._ID }             ,"mimetype=?",              new String[] { "vnd.android.cursor.item/vnd.com.whatsapp.profile" }, null);  c1.moveToFirst(); DatabaseUtils.dumpCursor(c1); c1.close();

Note (@Ragnar): MIMETYPE column didn't work for me. I used ACCOUNT_TYPE column and it worked.
