问题 I'm using AlarmManager to set up repeating intents but it has caused some little troubles so hope anyone could help. Summary There are 2 pending intents. One runs at 1000 and another runs at 2000 every day. Each contains a row id from the database for identification purpose. The code looks something like this: Intent i = new Intent(mContext, ScheduleReceiver.class); i.putExtra(RuleDBAdapter.KEY_ROWID, (int)taskId); PendingIntent pi =PendingIntent.getBroadcast(...); mAlarmManager.set

问题 What are the parameters of the following: alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_FIFTEEN_MINUTES, alarmIntent); And of the following: alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, alarmIntent); What is the difference and also how are the two different in terms of functionality? 回答1: Both examples schedule a repeating alarm that will send the given alarmIntent . On both

问题 I want for an event to fire every hour (at 5:00, 6:00, 7:00, etc...). I tried with a persistent background service with a thread but it wasn't the right solution because of: battery consumption service termination, due to android memory management So I'm trying with AlarmManager. It works if I set an alarm to fire in X seconds (using "set" method). But how can I repeat an event (using "setRepeating" method) at the top of every hour, until the alarm is canceled? Thanks! 回答1: When you set

问题 Documentation for PendingIntent.FLAG_NO_CREATE reads: Flag indicating that if the described PendingIntent does not already exist, then simply return null instead of creating it. My question: What criteria are used to compare PendingIntents? I'm guessing under the hood this flag uses PendingIntent.equals, but I'm not really sure what criteria that function is using.

Is this a normal behavior, is there any way to avoid this and keep the alarm running after closing the application? The code is below - the method
