Answer 1

myWhatsappContacts ArrayList will contain all the phone numbers that are present in your whatsapp Application.

Cursor cursor = getContentResolver().query(ContactsContract.Data.CONTENT_URI 
                  ,new String[] {ContactsContract.Data._ID
                               ,ContactsContract.Data.DISPLAY_NAME
                               ,ContactsContract.CommonDataKinds.Phone.NUMBER 
                               ,ContactsContract.CommonDataKinds.Phone.TYPE}
                  ,ContactsContract.Data.MIMETYPE + "='" + ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE
                  + "' AND " + ContactsContract.RawContacts.ACCOUNT_TYPE + "= ?"
                  ,new String[] { "com.whatsapp" }
                  , null);

    while (cursor.moveToNext())
    {

        myWhatsappContacts.add(cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))); 

    }

Answer 2

System.out.print("Name : "+cursor.getString(contactNameColumn) +"\n "+" Phone Number" + cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));

Answer 3

With the READ_CONTACTS permission in your manifest, you can get synced contacts given the account type. For WhatsApp it's "com.whatsapp". So:

Cursor c = getContentResolver().query(
        RawContacts.CONTENT_URI,
        new String[] { RawContacts.CONTACT_ID, RawContacts.DISPLAY_NAME_PRIMARY },
        RawContacts.ACCOUNT_TYPE + "= ?",
        new String[] { "com.whatsapp" },
        null);

ArrayList<String> myWhatsappContacts = new ArrayList<String>();
int contactNameColumn = c.getColumnIndex(RawContacts.DISPLAY_NAME_PRIMARY);
while (c.moveToNext())
{
    // You can also read RawContacts.CONTACT_ID to read the
    // ContactsContract.Contacts table or any of the other related ones.
    myWhatsappContacts.add(c.getString(contactNameColumn));
}
