I'm facing a little issue with my alarmManager. I'm trying to register an alarm to display a notification at spicified time. Here is how I'm doing it:
Utils.SetAlarm(this, Utils.GOODMORNING, 7, 0, 0); // so at 7:00
public static void SetAlarm(Context context, int req, int hour, int minute, int second) {
AlarmManager am = (AlarmManager) context.getSystemService(context.ALARM_SERVICE);
Intent intent = new Intent(context, myService.class);
intent.putExtra(ACTION_REQUEST, req);
PendingIntent pi = PendingIntent.getService(context, 0, intent, 0);
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, hour);
calendar.set(Calendar.MINUTE, minute);
calendar.set(Calendar.SECOND, second);
am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pi);
}
public class myService extends IntentService {
private static final int GOODMORNING_NOTIFICATION_REQUEST = 517;
public myService() {
super("myService");
}
@Override
protected void onHandleIntent(Intent intent) {
int extra = intent.getIntExtra(Utils.ACTION_REQUEST, 0);
if (extra == Utils.GOODMORNING) {
Notification notification = new Notification.Builder(this)
.setContentTitle("title")
.setContentText("content")
.setSmallIcon(R.drawable.ic_launcher)
.setAutoCancel(true)
.build();
NotificationManager notificationManager =
(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(GOODMORNING_NOTIFICATION_REQUEST, notification);
}
}
The issue I'm facing is that the notifcation appear immediatly after i run the Utils.SetAlarm void. It will also appear fine at 7:00 am so it's apparently working but i wonder if someone known a way to avoid this problem. Thanks
your were facing notification appear immediatly after you run the Utils.SetAlarm void.because of 7:00 am may have complete in your device so it's appears working at that instance.so try to set alarm for next day when current time is greater than alarm time
try this
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, hour);
calendar.set(Calendar.MINUTE, minute);
calendar.set(Calendar.SECOND, second);
long time=calendar.getTimeInMillis();
if(time<System.currentTimeMillis()){
time=time+AlarmManager.INTERVAL_DAY;
}
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,time,
AlarmManager.INTERVAL_DAY, alarmIntent);
