Hi there,
I have some problems when I try to setup an alarm. I am using the
AlarmManager to set an alarm. This alarm is picked up by my Receiver
that creates a notification.
My first problem: When I setup two alarms, my notification thats init
by the alarm event always shows me the first input parameter. Whats
going wrong?
My second problem: I read that I should use an id for the notification
to cancel it, when its submitted. What is the best way to create
different ids? I just used javas math. Although the ids are not equals
in my tests, it is not really a good solution. Any ideas?
Here is my code. Although the titleString is not the same like in the
first init (my Log entry in initializeAlarm() shows that the first
input not equals a second input) the onReceive method tells me that
todoTitle is always the same.
private void initializeAlarm(String titleString, String alarmString){
if(alarmString != null && alarmString.length() == 16){
Intent intent = new Intent(this, AlarmReceiver.class);
intent.putExtra("todoTitle", titleString);
PendingIntent sender = PendingIntent.getBroadcast(this, 0,
intent, 0);
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd
HH:mm");
Date date = new Date();
try {
date = sdf.parse(alarmString);
} catch (ParseException e) {
e.printStackTrace();
}
Calendar cal = Calendar.getInstance();
cal.setTime(date);
// Schedule the alarm!
AlarmManager am =
(AlarmManager)getSystemService(ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
sender);
Log.v("test",intent.getStringExtra("todoTitle"));
}
}
public class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
int notification_id =
(int)(Math.random()*100*Math.random()*100);
final Bundle extras = intent.getExtras();
String tickerText = extras.getString("todoTitle");
NotificationManager mNotificationManager = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.icon,
"Todo
News", System.currentTimeMillis());
Intent activityIntent = new Intent(context,
ToDosActivity.class);
activityIntent.putExtra("notificationId", notification_id);
activityIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent startIntent = PendingIntent.getActivity(context,
0,
activityIntent, 0);
notification.setLatestEventInfo(context, "Todo ansehen",
tickerText,
startIntent);
notification.vibrate = new long[]{100,250};
mNotificationManager.notify(notification_id, notification);
}
}
Thanks for any ideas!
