alarm

问题 I just looked through the AlarmService sample in the Android API Demo(API 8). When the AlarmManager in the AlarmService.java file use setRepeating() method to schedule the alarm, the service will create a new thread in the AlarmService_Service.java file. My question is: In the run() method of the mTask Runnable object, why it says "we will just sleep for 30 seconds."? My understanding is: the thread starts, and it waits/sleeps for 15 seconds(NOT 30 seconds), then this thread will be stop by

问题 I have created a widget to display the current date which refreshes every 5-10 seconds (Will be increasing the duration later). Created an alarm in the onUpdate method to create the intent for the service. Created an onReceive method extending broadcast receiver) to start the service which in turn updates the widget with the date. When I invoke the widget onReceive fires initially and displays the date. After that the alarm doesn't fire. 1) Am I right in including an onReceive method and

问题 I have an alarm that I am wanting to repeat around every 5 minutes. For testing purposes, I have it set to repeat once every 5 seconds instead, as such: AlarmManager alarmManager = (AlarmManager)getActivity().getSystemService(getActivity().ALARM_SERVICE); Intent intent = new Intent(getActivity(), CoordinateAlarmReceiver.class); PendingIntent pendingIntent = PendingIntent.getService(getActivity(), 1, intent, 0); int repeatSeconds = 5; alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP,

If the users set the alarm in a few minutes, it works. If it is set in a few hours, it might work, might be off by a few minutes or hours, most likely the latter. This is getting on my nerves, as I always get the complaints

问题 I have been unable to find a simple example which shows me how to use boto to terminate an Amazon EC2 instance using an alarm (without using AutoScaling). I want to terminate the specific instance that has a CPU usage less than 1% for 10 minutes. Here is what I've tried so far: import boto.ec2 import boto.ec2.cloudwatch from boto.ec2.cloudwatch import MetricAlarm conn = boto.ec2.connect_to_region("us-east-1", aws_access_key_id=ACCESS_KEY, aws_secret_access_key=SECRET_KEY) cw = boto.ec2

问题 I need to know if this is possible, and if it is, how I should proceed. I'd like to make an app that will create a repeating alarm within the stock Android Clock App. It should go off at 8am each morning and should only take one button to activate within my app. Thanks in advance 回答1: Try this: public void createAlarm(String message, int hour, int minutes) { Intent intent = new Intent(AlarmClock.ACTION_SET_ALARM) .putExtra(AlarmClock.EXTRA_MESSAGE, message) .putExtra(AlarmClock.EXTRA_HOUR,

问题 I have a service that tracks the user locations. It doesn't have to run 24x7 but it should run for the duration of the trip. Following are the things that I have implemented till now to ensure it's continuous functioning : started service as foreground used "START_STICKY" started an alarm which checks every 10 mins if service is running. If not it starts service. Despite of all these measures, for some devices(like MI 3w) service gets killed within 10 mins and doesn't restart at all(not even
