alarmmanager

问题 I am trying to use BroadcastReceiver and AlarmManager to set a one-shot alarm. I have no idea why isn`t it working. What am I doing wrong? I have no exceptions, no logs about, no suggestions from IDE, everything seems fine, but onReceive method in my BroadcastReceiver is never called. public void setAlarm(Context mContext) { AlarmManager alarmManager = (AlarmManager) mContext.getSystemService(Context.ALARM_SERVICE); Intent intent = new Intent(mContext, AlarmReceiver.class); PendingIntent

问题 I have this code: set alarm: public void setAlarm() { Calendar Calendar_Object = Calendar.getInstance(); Calendar_Object.add (Calendar.DAY_OF_YEAR, 1); Calendar_Object.set(Calendar.HOUR_OF_DAY, 0); Calendar_Object.set(Calendar.MINUTE, 0); Calendar_Object.set(Calendar.SECOND, 1); Intent myIntent = new Intent(Main.this, AlarmReceiver.class); PendingIntent pendingIntent = PendingIntent.getBroadcast(Main.this, 0, myIntent, PendingIntent.FLAG_CANCEL_CURRENT); AlarmManager alarmManager =

问题 I want to use Androids sensor batching introduced in Android 4.4 to save some battery power. My testing device can store 184 sensor events in its fifo-queue. Using a sampling rate of 18 events/seconds I have to flush the sensor about every 10 seconds. The section on Sensor Batching in the 4.4 Documentation proposes: Use that calculation to set wake alarms with AlarmManager that invoke your Service (which implements the SensorEventListener) to flush the sensor. Since Android 5.1 the minimum

问题 I schedule pendingIntent to be sent in 5 seconds, but it starts in 23 seconds. API=19 (AlarmManager.setExact(...)): 10-23 16:43:44.638 11903-11903/?

问题 I'm coding an alarm clock application, and i would like to know what happens, when I set some alarm with AlarmManager for example at time 2:59am (this is not time of my alarm, this is only time WHEN i set some alarm), and at 3:00am there will be automatic time change from summer time to winter (DST). What happens with my scheduled alarm? I found nothing in docs, and it's not so easy to test, at least I must change dates and wait few hours...I'm not so patient ;) Next problem - I was also

问题 So I have been working on medication intake app, where I need to remind the user locally ( no internet/push notification needed) about taking their medication. I am using Android Alarm manager for this. Below is the code Note I am trying to schedule the alarm for a specific date: "13 July 2018 at 3h30 PM" . I schedule and wait but the reminder didn't fire (so not broadcast) however if I used AlarmManager.ELAPSED_REALTIME_WAKEUP with a defined amount of millisecond it does fire ( but

问题 here is what am trying to accomplish and badly failing at it. I need to: -start a service -do some tasks -set AlarmManager to start the service again after a set period of time -stop the service the problem I'm having is that the service is being re-started almost immediately it is being stopped. All I want is that the service should start after the alarm goes off.. Here is the code:- Intent intent = new Intent(ThisService.this, ThisService.class); PendingIntent pendingIntent = PendingIntent

问题 User can create different alarms. So it's up to user when to keep alarm and he can keep multiple alarms and I maintain all the scheduled alarms in a database and show to the user for further reference. Below is my code. if("CREATEONCE".equals(strparam1)) { am.set(AlarmManager.RTC_WAKEUP, l2, pi);// l2 is time in millis }else if("CREATEREPEAT".equals(strparam1)) { am.setRepeating(AlarmManager.RTC_WAKEUP, l2, 86400000 , pi); //l2 is time in millis } So this is the code which sets the alarms.

问题 this is my code for menage a single notification: myActivity.java public class myActivity extends Activity { protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.mylayout); cal = Calendar.getInstance(); // it is set to 10.30 cal.set(Calendar.HOUR, 10); cal.set(Calendar.MINUTE, 30); cal.set(Calendar.SECOND, 0); long start = cal.getTimeInMillis(); if(cal.before(Calendar.getInstance())) { start += AlarmManager.INTERVAL_FIFTEEN_MINUTES;

问题 (I'm asking here because I didn't get help at Xamarin forums) I'm creating an alarm with this code: Intent alarmIntent = new Intent(context, typeof(AlarmReceiver)); notificationClickIntent = PendingIntent.GetActivity(context, 0, new Intent(), 0); pendingIntent = PendingIntent.GetBroadcast(context, 0, alarmIntent, PendingIntentFlags.UpdateCurrent); am = (AlarmManager)Android.App.Application.Context.GetSystemService(Context.AlarmService); DateTime setTime = new DateTime(temp.Ticks + offset); /
