alarmmanager

问题 What is the best way to implement repeating alarm in my android application? Every user selects a specific time and I want to notify them when this time approaches on daily bases. I have come across this, but I am wondering whether this is the best way? 回答1: The alarm manager should meet your needs. There is no better way except for maybe having a server ping your client. Since android really doesn't like things that repeat on a predictable interval, and since recent versions don't let you

问题 I developed an Alarm clock. A main screen witch lists all alarms and add option to add new alarm to list. I am using an Alarm Manager to fire a notification or open user screen. After user open notification screen and hit button, it returns to main screen and list all alarms. All alarms that already fired, and will not fire again, are marked with different color. To identify witch alarms are fired, I am using this code: How to check if AlarmManager already has an alarm set? But this code is

问题 I'm writing an application which is continuously listening and checking the sensors (almost all available) and saving that data into the database in the device. I need to make some calculations every X second with that data and throw a new event if the calculations check says so. I'm thinking about requesting to have the device plugged in while using the application (regarding battery drain). What's the best approach for the task that needs to make the calculations and throw the event? Timer?

问题 I want to get a notification every day (at 13:00) with alarmManager , but when the device is restarted, the alarm is active for one day only and does not work for 2nd or 3rd day unless I run my application. Why does it run only once? MainActivity.class: public class MainActivity extends ActionBarActivity implements OnClickListener { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); alarmKurulum(); } public void alarmKurulum() { Intent alarmIntent = new Intent

问题 I want to show notification every minute using Alarm Manager, I have implemented below code, it's working fine but the problem is when I remove app from stack the service is not running. I want keep alive, I have tried START_STICKY in onStartCommand and also used onTaskRemoved but it's same. I also tried to implement using WakefulIntentService but the problem is same. My code is below. In MainActivity Intent myIntent = new Intent(NotificationDemo.this, MyReceiver.class); myIntent.putExtra(

问题 I have created an alarm with a notification and a button to stop the alarm but it seems that there is some issue with the Context that I have to get in order to cancel the AlarmManager . I have researched a lot and I think I have applied most of the things I found but somehow can't get this to work. I am aware the PendingIntent has to be the same and it appears to me they are with the same request codes too. AlarmSlave.class - Sets Alarm public class AlarmSlave /*extends Service*/ { private

问题 I've got a timepicker to set the alarm public class TimePickerFragment : DialogFragment, TimePickerDialog.IOnTimeSetListener { public static readonly string TAG = "MyTimePickerFragment"; Action<DateTime> timeSelectedHandler = delegate { }; public static TimePickerFragment NewInstance(Action<DateTime> onTimeSelected) { TimePickerFragment frag = new TimePickerFragment(); frag.timeSelectedHandler = onTimeSelected; return frag; } public override Dialog OnCreateDialog(Bundle savedInstanceState) {

问题 Before closing this issue or marking as duplicate based on the title, it is different from the regular "cancel alarm using AlarmManager and PendingIntent" questions. I am capable of creating and cancelling pending intents, as long as they are set for a time in the future and haven't gone off yet. I'm testing this using the following terminal command to view the PendingIntent s before creating an alarm as well as after: adb shell dumpsys alarm Here is my code for scheduling alarms in my custom

问题 I have a test screen where there is a button - where it is pressed it calls the service.

Can anyone tell what the problem is? package com.example.whereyouapp; import java.util.Arrays; import android.app.AlarmManager; import android.app.PendingIntent; import android.app.Service; import android.content.ContentValues; import android.content.Context; import android.content
