android - Nullpointer at creating PendingIntent -

-

i nullpointer @ intent alarmintent = new intent(this, mynotification.class); have no idea how fix this.. hope might able me..

what should set alarm everyday @ 9 can set notification in mynotification class contains broadcastreceiver.

below code:

calling alarmmanager class (from mainactivity):

alarm setalarm = new alarm();         setalarm.setrecurringalarm();

the class want set alarmmanager (alarm.class):

public class alarm extends activity { public void setrecurringalarm() {      log.i("alarm", "setting recurring alarm");      calendar updatetime = calendar.getinstance();      updatetime.set(calendar.hour, 7);     updatetime.set(calendar.minute, 0);     updatetime.set(calendar.second, 0);      intent alarmintent = new intent(this, mynotification.class);     pendingintent recurringdownload = pendingintent.getbroadcast(this, 0, alarmintent, pendingintent.flag_cancel_current);     alarmmanager alarms = (alarmmanager) getsystemservice(context.alarm_service);     alarms.cancel(recurringdownload);     alarms.setinexactrepeating(alarmmanager.rtc, updatetime.gettimeinmillis(), alarmmanager.interval_day , recurringdownload); }

}

logcat output:

just wondering, why doing way, instead of putting setrecurringalarm() method in mainactivity?

you creating instance of alarm activity, , calling method on it. dont see need in activity.

just guessing, using alarm activity context without being launched causing nullpointerexception.

i've plotted data points , fitted exponential curve between them using 'fit' in matlab. problem fit-function got fitted line wanted plot, markers on top of regular markers. solved problem plotting wanted markers on top of unwanted couldn't seen. problem. when want show legends dots in there. how can remove markers legend without removing fitted line since both of them hidden inside fit-function? can stop 'fit' plotting unwanted markers? so, want remove blue dot called 'hoff' in picture below. you can leave out legend-entries manually leaving out handles of lines, dont want in legend. try this: %if plot something, want showing in legend, save handle: h_line = plot(x,y) %you dont want show line? dont anything, plot it: plot(mymarker) %then set legend-> can add text legend-entries %a cell-array containing strings want show up: legend([h_line another_line],{'text1' 'text2'}) with example (see comments) came solution: ...
