Experts:
Any experts on AlarmManager out there? I've got something weird going on.
The basic code to set my repeating alarm works fine. I can close my app and
the alarm will continue to run like clockwork every five minutes. It works
fine only if I set it in the app and then close the app. The code is below:
--------------------------------------------------------------------------
Intent intent = new Intent(this, AlarmReceiver.class);
Bundle b = new Bundle();
b.putLong("res_id", res_id);
intent.putExtras(b);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent,
0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
(System.currentTimeMillis() + (5 * 1000)), (5 * 60000), pendingIntent);
--------------------------------------------------------------------------
I've got a registered BootReceiver for re-registering the repeating alarm.
I know it fires on boot b/c the log message clearly shows it is firing and
re-setting the repeating alarm in question for the same frequency.
But the AlarmManager is not firing. Basically, the nearly identical code
for setRepeating() fires when set from the app and continues to run when the
app is closed, so I know my AlarmReceiver is functioning, but the
AlarmManager is either not broadcasting this alarm or my receiver doesn't
work from an alarm set in the boot receiver. Below is the code for setting
the alarm from the BootReciver:
--------------------------------------------------------------------------
Intent i = new Intent(context, AlarmReceiver.class);
Bundle b = new Bundle();
b.putLong("res_id", res_id);
i.putExtras(b);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context,
(int)res_id, i, 0);
AlarmManager alarmManager = (AlarmManager)
context.getSystemService(Context.ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
(System.currentTimeMillis() + (5 * 1000)), (5 * 60000), pendingIntent);
--------------------------------------------------------------------------
I read somewhere that the AlarmReceiver definition in the manifest needs an
intent-filter or 2 specified. I don't have any intent-filters, nor would I
know what to put in there. Is that perhaps why? I mean it could make sense
b/c the call to setRepeating from the activity w/in my app would still work
b/c the broadcast has more information about what receiver needs the alarm,
whereas when it's being set from the bootreceiver, the receiver in my
manifest isn't defined well enough to get the broadcast? Here's my manifest
definition for the receiver:
<receiver android:name=".AlarmReceiver" android:process=":remote" />
At the following PDF (Page 25), it suggests a fully-qualified app name
intent-filter:
