how to get whats app contacts' phone numbers

Question

Hi I am currently trying to implement WhatsApp with an application I am working on. I want to be able to display all the WhatsApp contacts that a user has along with their phone number. So far I have been able to grab the name of their WhatsApp contact but I have not been able to grab the phone number of their WhatsApp contact, here is the code that I am using to get the list of a users WhatsApp contacts.

cursor = cr.query(ContactsContract.RawContacts.CONTENT_URI, new String[] {
    ContactsContract.RawContacts.CONTACT_ID, ContactsContract.RawContacts.DISPLAY_NAME_PRIMARY
}, ContactsContract.RawContacts.ACCOUNT_TYPE + "= ?", new String[] {
    "com.whatsapp"
}, null);
int contactNameColumn = cursor.getColumnIndex(ContactsContract.RawContacts.CONTACT_ID);
while (cursor.moveToNext()) {
    String name = cursor.getString(contactNameColumn);
    System.out.println(name);
    Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] {
        Integer.toString(contactNameColumn)
    }, null);
    while (pCur.moveToNext()) {
        String phonenumber = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
        System.out.println("PHONE: " + phonenumber);
    }
    pCur.close();
}
cursor.close();

When I print out the name it prints it out correctly, I then use that id to query the data table in order to get their phone number, but that always returns null, can anyone help me out please.

Thanks

tried to use `DatabaseUtils.dumpCursor()` for an outer cursor? for testing change projection param (`new String[] { ContactsContract.RawContacts.CONTACT_ID, ContactsContract.RawContacts.DISPLAY_NAME_PRIMARY }`) to null — pskink, Jun 23 '15 at 05:31

Use following code to get WhatsApp contacts from Phonebook with associated whatsApp number :

private void displayWhatsAppContacts() {

    final String[] projection = {
            ContactsContract.Data.CONTACT_ID,
            ContactsContract.Data.DISPLAY_NAME,
            ContactsContract.Data.MIMETYPE,
            "account_type",
            ContactsContract.Data.DATA3,
    };

    final String selection = ContactsContract.Data.MIMETYPE + " =? and account_type=?";
    final String[] selectionArgs = {
            "vnd.android.cursor.item/vnd.com.whatsapp.profile",
            "com.whatsapp"
    };

    ContentResolver cr = getContentResolver();
    Cursor c = cr.query(
            ContactsContract.Data.CONTENT_URI,
            projection,
            selection,
            selectionArgs,
            null);

    while (c.moveToNext()) {
        String id = c.getString(c.getColumnIndex(ContactsContract.Data.CONTACT_ID));
        String number = c.getString(c.getColumnIndex(ContactsContract.Data.DATA3));
        String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

        Log.v("WhatsApp", "name " +name + " - number - "+number);

    }
    Log.v("WhatsApp", "Total WhatsApp Contacts: " + c.getCount());
    c.close();
}

Change your pCur like this

     if (name != null) {
                    Cursor pCur = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[]{name}, null);
                    //Iterate cursor here...
                    }

And it is better to use proper naming conventions for variables. Why because here the varible name represents the id of the conatact.
