I was trying to make an app that automatically detects the OTP send via the default Android messaging app -

-

here code:

 btnsend.setonclicklistener(new view.onclicklistener() {      @override      public void onclick(view v) {         final string sentotp = randomnum();         if (!etnumber.gettext().tostring().trim().equals("")) {         uri uri = uri.parse("smsto:" + etnumber.gettext().tostring().trim());         intent smsintent = new intent(intent.action_sendto, uri);         smsintent.setflags(intent.flag_activity_new_task);         smsintent.putextra("sms_body", sentotp);         startactivity(smsintent);         inish();         intent = new intent(sendactivity.this, checkeractivity.class);         i.setflags(intent.flag_activity_new_task);         i.putextra("generatedotp", sentotp);         startactivity(i);         finish();         toast.maketext(sendactivity.this, "enter phone number!!", toast.length_long).show();         }    } });

upon clicking button, messaging app opens , backgrounded checkeractivity started. want when message app opens, send message, , click send button send message, checkeractivity gets started.

how can accomplish this? need set additional intent flags?

start sms intent results, on results can start activity.
