A user selects alarm settings and then a intent is loaded with extras
and passed to start alarm ... which starts the pending intent
/* Starts alarm for one-time-occurrence system wide. Application must
start alarm again after occurrence. */
public static long startAlarm(Context context, Intent alarm, Class<?>
receiver) {
long dateOccur = -1;
// build pending intent
alarm.setClass(context, receiver);
PendingIntent alarmIntent = PendingIntent.getBroadcast(context,
API_ID+alarm.getIntExtra(ALARM_ID, -1), alarm,
PendingIntent.FLAG_CANCEL_CURRENT);
.... /// MORE STUFF
}
After the pending intent is receivedivity t I launch a new activity to
alert the users and give them a snooze/dismiss option.
BROADCAST RECEIVER CLASS
@Override
public void onReceive(Context context, Intent intent) {
// it is imperative to strip snooze
if (intent.hasExtra(AlarmHandler.ALARM_SNOOZE)) {
//Log.d(MainActivity.DEBUG_ID, "This is a SNOOZE
alarm.");
intent.removeExtra(AlarmHandler.ALARM_SNOOZE);
}
PowerManager pm = (PowerManager)
context.getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wake
=pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK |
PowerManager.ACQUIRE_CAUSES_WAKEUP, "ConcProd");
wake.acquire();
AlarmActiveActivity.wake = wake;
// launch notification activity
intent.setClass(context, AlarmActiveActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}
Then from the alert activity that is fired I use the OnClick to set a
snooze option ... and call the startAlarm again using the orig intent
that was passed to it.
@Override
public void onClick(View view) {
// cancel sounds
mNotification.cancelAll();
//DISSMISS SNOOZE!
// depending on action this is where we will reset the alarms
if (view.getId() == R.id.btnSnooze) {
// snooze is a fun alarm set for 5 minutes away!
mAlarm.putExtra(AlarmHandler.ALARM_SNOOZE, true);
AlarmHandler.startAlarm(this, mAlarm,
AlarmReceiver.class);
}
wake.release();
finish();
}
if the onclick wasn't fired it means that the alarm was simply
dismissed and I call startAlarm to start it again for the next day...
@Override
protected void onDestroy() {
// we will assume dismiss if not snoozing so just reset
if (!mAlarm.getBooleanExtra(AlarmHandler.ALARM_SNOOZE, false))
if (mAlarm.getBooleanExtra(AlarmHandler.ALARM_ENABLED,
false)) {
AlarmHandler.startAlarm(this, mAlarm,
AlarmReceiver.class);
}
super.onDestroy();
}
It is confusing and I'm not sure how to explain it ...
I observe that in only occurs after FLAG_NEW_ACTIVITY_FLAG has been
assigned to the original intent to fire the notification window?
No sure why it doesn't happen in SDK < 2.0
