How to get Contact ID, Email, Phone number in one SQLite query ? Contacts Android Optimization

I want to fetch All Contacts atleast with one phone Number, also I want all Phone Numbers and All emails for every Contact.

Current code :

// To get All Contacts having atleast one phone number.

Uri uri = ContactsContract.Contacts.CONTENT_URI;
String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER + " > ?";
String[] selectionArgs = new String[] {"0"};
Cursor cu = applicationContext.getContentResolver().query(uri, 
                null, selection, selectionArgs, null);

// For getting All Phone Numbers and Emails further queries : 
while(cu.moveToNext()){
String id = cu.getString(cu.getColumnIndex(ContactsContract.Contacts._ID));


 // To get Phone Numbers of Contact
    Cursor pCur = context.getContentResolver().query(
    ContactsContract.CommonDataKinds.Phone.CONTENT_URI,  null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=?",
 new String[]{id}, null);

// To get Email ids of Contact
Cursor emailCur = context.getContentResolver().query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
new String[]{id}, null); 

// Iterate through these cursors to get Phone numbers and Emails
}

If there are more than 1000 contacts in my Device, it is taking too much time. How can I get All Data in single query, rather than doing two additional queries for each contact?

Or is there any other way to optimize?

Thank you in Advance.
