from answer, android alarm difference between 4 types of alarm alarmmanager provides , when use what?

also tells difference in types of alarms, https://developer.android.com/training/scheduling/alarms.html

elapsed_realtime

it trigger since boot time. if set 300000 alarm trigger every 5 minutes , not take current time in consideration.

rtc

it trigger per clock time meaning not take boot time in consideration , trigger @ time specified.

to wake device use this,

alarmmanager.setrepeating(alarmmanager.elapsed_realtime_wakeup, triggertime, minterval, pendingintent); 

else use if don't want wake device

alarmmanager.setrepeating(alarmmanager.elapsed_realtime, triggertime, minterval, pendingintent);
