问题 What is difference between AlarmManager.setAndAllowWhileIdle() and AlarmManager.setExactAndAllowWhileIdle() ? How does these both affect Doze mode introduced in Android 6.0 (Marshmallow) API? 回答1: Refer to the documentation of AlarmManager : Note: Beginning with API 19 (KITKAT) alarm delivery is inexact: the OS will shift alarms in order to minimize wakeups and battery use. There are new APIs to support applications which need strict delivery guarantees; see setWindow(int, long, long,

问题 So basically I have this code, time returns 24hour time and repeats the alarm daily. public setAlarm(String time, Context context){ String[] strTime; strTime = time.split(":"); int hour, min, sec; //set when to alarm hour = Integer.valueOf(strTime[0]); min = Integer.valueOf(strTime[1]); sec = 0; Calendar cal = Calendar.getInstance(); cal.set(Calendar.HOUR_OF_DAY, hour); cal.set(Calendar.MINUTE, min); cal.set(Calendar.SECOND, sec); //Create a new PendingIntent and add it to the AlarmManager

问题 I use AlarmManager to schedule multiple taks, i.e. Task 1 at 10:56, Task 2 at 11:24 and so on. Here's the code: intent = new Intent(ACTION_RECORDER_START); intent.putExtra(EXTRA_COMMAND_ID, command.id); pendingIntent = PendingIntent.getService(context, 0, intent, PendingIntent.FLAG_ONE_SHOT); alarmManager.set(AlarmManager.RTC_WAKEUP, command.start, pendingIntent); Here's the strange thing: If I set one alarm, it does job well. If I set two, only the last alarm is fired. So, I guess the

问题 I have programmed an alarm system that synchronizes with the server where are the information. Sometimes, in the updates on the server some alarms are deleted. Now, it is well removed from the database db4o but I can't cancel pendingIntents already programmed.

问题 I am working on adding multiple alarm functionality in my existing app. Earlier, the alarm was single only and every thing worked fine. I have been able to set multiple alarms, it is working fine too, but problem is with snooze feature. Earlier, snooze was working perfect. But, after multiple alarm implementation it is not working. I never get dialog for snoozing alarm, once I press snooze button. Here is my code: Set alarm method public void setAlarm(boolean AlarmEnabled, int AlarmHour, int

问题 I have used the same pendingIntent to set multiple alarms using different intentId for each. the alarm is working. Now i want to cancel a particular alarm. If i use the cancel() method i would end up cancelling all the alarms. I want only a specific one to be deleted. Also the user should be able to cancel this alarm even during a second or a third launch. As in when i launch it the second time, i won't be having the same pendingIntent object. Would i have to persist the pendingIntent object?

问题 I want to set up a timer in an Android application that will call a function after every 15/30/45 and n minutes when user login. But also it will stop timer when user log off. and timer begin from start if user login again. I want that option(15/30/45/n miutes) to be saved in database so that I can update list after sync.
