android - PendingIntent null when trying to call it from a class -


im bulding alarm clock, , got pendingintent should snooze alarm. same code worked great when in activity. change things, , in different class. nullpointerexecption. (the contractor gets context activity.

snooze function:

public void settingnewintentforsnooze() {     pendingintent alarmpendingintent=null;     calendar calendar = calendar.getinstance();     // new alarm after snooze.     calendar.set(calendar.minute, calendar.get(calendar.minute) + snoozetime);     intent snoozeintent = new intent(context, alarm_reciver.class);     snoozeintent.putextra("click_status", true);     //add try solve problem...     snoozeintent.setaction("snooze");     alarmpendingintent = pendingintent.getbroadcast(context, 0, snoozeintent, alarmpendingintent.flag_one_shot);     //tells phone set alarm     alarm_manager.set(alarmmanager.rtc_wakeup, calendar.gettimeinmillis(), alarmpendingintent); }

alarmpage activity(the code creats variable) :

snooze= new snooze(this,alarm_manager);

alarmreciver:

public void onreceive(context context, intent intent) {     log.e("in alarm reciver","in alarm reciver");     intent service_intent= new intent(context, ringtoneplayingservice.class);//intent service ringtone playing     boolean button_status = intent.getextras().getboolean("click_status");     service_intent.putextra("click_status", button_status);//passing button status     context.startservice(service_intent);//start ringtone service }

the error:

judging error message, possible alarm_manager null? if initialize alarmmanager properly, error go away?
