                    /*contacts.setAction(android.content.Intent.ACTION_VIEW);
                    contacts.setData(People.CONTENT_URI);*/
                    startActivityForResult(intent_contacts, 0);

            {
                Uri contactdata  = data.getData();

                Cursor cur = managedQuery(contactdata, null, null, null, null);


                if(cur.moveToFirst())
                {
                    id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
                    Cursor emailCur = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,null,
                            ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",new String[]{id}, null); 
                    emailCur.moveToFirst();
                    String email = emailCur.getString(emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));


                    name = cur.getString(cur.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
                    //mailid = cur.getString(cur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
                    mailid = cur.getString(cur.getColumnIndex(ContactsContract.CommonDataKinds.Email._ID));
                    //Toast.makeText(context_contact, "Name:"+name+"\nmailid:"+email, Toast.LENGTH_SHORT).show();
//your code to put data in arraylist                        
/*Intent intent_add_invitees = new Intent(<ClassContext>,<ActivityName>.class);
                    intent_add_invitees.putExtra("invitee_name", name);
                    intent_add_invitees.putExtra("invitee_mailid", email);
                    setResult(RESULT_OK, intent_add_invitees);
