device admin - Android: not showing messages on onPasswordFailed -

i have implemented own class, extending deviceadminreceiver, given app appropriate authorities run etc.

i have tried display message (as simple toast below, , starting new activity) when user has entered wrong pin, cannot working. code executes intended, messages showing until after entering correct pin.

are there special tricks need do, or screen restricted in android?

(probably not need run super.onpasswordfailed(), please disregard now)

@override public void onpasswordfailed(context context, intent intent) {     super.onpasswordfailed(context, intent);     log.i("myapp: ", "swdeviceadminreceiver::onpasswordfailed");      toast.maketext(context, "password failed", toast.length_short).show(); }
