android - Alarm Manager goes off as i click the Button -

i have code set on button sets alarm manager send broadcast , activate wifi on device. have set delay 1 min code alarm goes off click button

here's code on button:

public void start(view view){         alarmmanager alarm = (alarmmanager) getsystemservice(alarm_service);         intent intent1 = new intent(this,myreceiver.class);         pendingintent turnwifi = pendingintent.getbroadcast(getapplicationcontext(), 0, intent1, 0);         long milli = 60000;         alarm.set(alarmmanager.rtc,milli,turnwifi);     } 

the code in receiver:

public class myreceiver extends broadcastreceiver{      @override     public void onreceive(context context, intent intent) {         log.i("broadcastreceiver","------------>in on receive method<-------------");         wifimanager wifi_man = (wifimanager) context.getsystemservice(context.wifi_service);         wifi_man.setwifienabled(true);      } 

in alarm.set(alarmmanager.rtc,milli,turnwifi); milli passed
use calendar less complexity.

this should solve problem:
alarm.set(alarmmanager.rtc,system.currenttimemillis() + milli,turnwifi);

update:

explanation:

if stated trigger time in past, alarm triggered immediately

trigger alarmmanager.rtc (real time clock) type time of day represented milliseconds. , 60000 millis literally in past.

according documents, system.currenttimemillis() + 60000 goes off in next 60secs

system.currenttimemillis()
returns current time in milliseconds since january 1, 1970 00:00:00.0 utc.
