Android Get a Cursor Only with Contacts That Have an Email Listed >Android 2.0

Android get a cursor only with contacts that have an email listed android 2.0

I solved this one, here is how its done:

UPDATE

   String[] PROJECTION = new String[] { ContactsContract.RawContacts._ID,
        ContactsContract.Contacts.DISPLAY_NAME, ContactsContract.Contacts.PHOTO_ID,
        Email.DATA, ContactsContract.CommonDataKinds.Photo.CONTACT_ID };

    String order = " CASE WHEN " + ContactsContract.Contacts.DISPLAY_NAME
        + " NOT LIKE '%@%' THEN 1" + " ELSE 2 END, "
        + ContactsContract.Contacts.DISPLAY_NAME + " COLLATE NOCASE";
    String filter = Email.DATA + " NOT LIKE '' ) GROUP BY ( " + Email.DATA;

    return mContent.query(Email.CONTENT_URI,
                      PROJECTION, filter, null, order);

Get only email address from contact list Android

public ArrayList<String> getNameEmailDetails(){
        ArrayList<String> names = new ArrayList<String>();
        ContentResolver cr = getContentResolver();
        Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
        if (cur.getCount() > 0) {
            while (cur.moveToNext()) {
                String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
                Cursor cur1 = cr.query( 
                        ContactsContract.CommonDataKinds.Email.CONTENT_URI, null,
                        ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", 
                                new String[]{id}, null); 
                while (cur1.moveToNext()) { 
                    //to get the contact names
                    String name=cur1.getString(cur1.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
                    Log.e("Name :", name);
                    String email = cur1.getString(cur1.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
                    Log.e("Email", email);
                    if(email!=null){
                        names.add(name);
                    }
                } 
                cur1.close();
            }
        }
        return names;
    }

the above method return an arraylist of names which has email id.

Get contact names with email address

Try following code

private static final String[] PROJECTION = new String[] {
    ContactsContract.CommonDataKinds.Email.CONTACT_ID,
    ContactsContract.Contacts.DISPLAY_NAME,
    ContactsContract.CommonDataKinds.Email.DATA
};

...

ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, PROJECTION, null, null, null);
if (cursor != null) {
    try {
        final int contactIdIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.CONTACT_ID);
        final int displayNameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
        final int emailIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA);
        long contactId;
        String displayName, address;
        while (cursor.moveToNext()) {
            contactId = cursor.getLong(contactIdIndex);
            displayName = cursor.getString(displayNameIndex);
            address = cursor.getString(emailIndex);
            ...
        }
    } finally {
        cursor.close();
    }
}

Checking if contact has an email address without a second query

After thinking for a while a realized I only need the email of the contact that you click on, so I just removed the email code from the asynctask and made another asynctask that loads an email of a specific contact. Then I get the email of the contact that was clicked and fill the email field. Code can be found in the repository I linked to in the question.
