I want to set phones alarm in phone.
Can anybody say how to do that?
I got the code from net, and try but the alram not set to phone.
Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(System.currentTimeMillis());
Intent activate = new Intent(this, Alaram.class);
AlarmManager alarams ;
PendingIntent alarmIntent = PendingIntent.getBroadcast(this, 0, activate, 0);
alarams = (AlarmManager) getSystemService(ALARM_SERVICE);
alarams.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), alarmIntent);
In this code we are provide intent as Alaram.class.
Then what should be written in this Alram.class so that alarm will set to the mobile.
I think you misunderstood what the AlarmManager is good for. It starts your code on a given Point, it doesn't set the phones ring tone.
If you want to set the Phones Alarm sound, this might be helpful (from the standard Android Music Player):
// Set the system setting to make this the current ringtone
MusicUtils.setRingtone(this, mService.getAudioId());
You are setting alarm time as current time in millisecond it will be exceed when the alarmmanager wake up....So,here i modified your code.check this it will work.That alaram will start after 5 seconds...i mean your Alaram activity will start within 5 seconds.
Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(System.currentTimeMillis());
Intent activate = new Intent(this, Alaram.class);
AlarmManager alarams ;
PendingIntent alarmIntent = PendingIntent.getBroadcast(this, 0, activate, 0);
alarams = (AlarmManager) getSystemService(ALARM_SERVICE);
alarams.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis()+5000, alarmIntent);

I have 2 alarms set, one for notifications, and the other one to do some tasks. My problem is that only one alarm seems to work( the notifications service one, the first alarm set). The Other alarm never goes off. Here is my code :
Intent myIntent1 = new Intent(getApplicationContext(), NotificationService.class);
PendingIntent pendingIntent = PendingIntent.getService(getApplicationContext(), 0, myIntent1, 0);
AlarmManager alarmManager1 = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
Calendar calendar1 = Calendar.getInstance();
calendar1.setTimeInMillis(System.currentTimeMillis());
long frequency1 = 30 * 1000; // in ms
alarmManager1.setRepeating(AlarmManager.RTC_WAKEUP, calendar1.getTimeInMillis(), frequency1, pendingIntent);
// Set alarm to fire go to Next day everyday at the same time
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 14); // For 1 PM or 2 PM
calendar.set(Calendar.MINUTE, 57);
calendar.setTimeInMillis(System.currentTimeMillis());
Intent myintent = new Intent(getApplicationContext(), AlarmNextDayService.class);
AlarmManager alarmManager = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
PendingIntent pi = PendingIntent.getService(getApplicationContext(), 11, myintent,0 );
alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY, pi);
Any suggestions are welcome. I have looked atother sources as well nothing works for me till now.
I have also added alarm permisison in the manifest file as the following :
<uses-permission android:name="com.android.alarm.permission.SET_ALARM"/>
Thank you
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 14); // For 1 PM or 2 PM
calendar.set(Calendar.MINUTE, 57);
calendar.setTimeInMillis(System.currentTimeMillis());
You are setting the HOUR_OF_DAY and the MINUTE but them you override that by calling setTimeInMillis(System.currentTimeMillis());
After that you set the alarm with the calendar.getTimeMillis() value which is already in the past, so the alarm is cancelled I think.
You're most likely seeing an issue because a Service is not guaranteed to run when triggered by an alarm, due to power save. If your device is on battery and idle when that alarm goes off, it will not trigger until the next time the device is full on or on AC power. You'll need to use a BroadcastReceiver which holds a wake lock which is then released by the Service when it is done. The WakefulBroadcastReceiver makes this a little easier to handle. This article will help provide more details.
In my app, I have an AlarmManager set up that runs every 5 mins, triggering a service. However I find that in Lollipop phones, it works only after I reboot the phone. If I do not reboot the phone, the AlarmManager never runs. Please let me know if you might be able to help me out with some hints. Appreciate your help.
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.add(Calendar.SECOND, 120);
Intent intentAlarm = new Intent(appContext, CheckConnReceiver.class);
PendingIntent pendingIntent
= PendingIntent.getBroadcast(appContext, 0, intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT);
// create the object
AlarmManager alarmManager = (AlarmManager) appContext.getSystemService(Context.ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
calendar.getTimeInMillis(), 300000, pendingIntent);
Am creating an application that fetch data from webservice. I have been while(true) and sleeping the loop at a specific milliseconds.. i had like to make the service action(fetching data from webservice) to always start at a specific time.. instead on being on always and pausing by Thread.sleep(milli)... Thanks
this is what have been using
while(true)
{
///pullDataFromWebservice();
Thread.sleep(600000);
}
Use the Alarm API. It is way safer than having a sleep & poll service.
Why?
Because Android is very likely to reclaim such a long running services when resources turn low, resulting
in your delayed logic never being called!
An example for activating a callback in 1 hour from now:
private PendingIntent pIntent;
AlarmManager manager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, MyDelayedReceiver.class); <------- the receiver to be activated
pIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
manager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP,
SystemClock.elapsedRealtime() +
60*60*1000, pIntent); <---------- activation interval
Try using AlarmManager - A bit battery eater though
AlarmManager alarmMgr = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(this, YourClass.class);
PendingIntent pIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
Calendar cal= Calendar.getInstance();
cal.set(Calendar.HOUR_OF_DAY, 19);
cal.set(Calendar.MINUTE, 20);
cal.set(Calendar.SECOND, 0);
alarmMgr.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pIntent);
//RTC_WAKEUP to enable this alarm even in switched off mode.
I am trying to set periodically alarm every 30 minutes, but i dont think it is working. I use below code:
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(MyActivity.this, Alarm.class);
PendingIntent alarmIntent = PendingIntent.getBroadcast(MyActivity.this, 0, intent, 0);
long selectedTimeMiliseconds = (long) (TimeUnit.MINUTES.toMillis(30));
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), selectedTimeMiliseconds, alarmIntent);
How to set the second parameter in method setInexactRepeating? Is it better to use setRepeating method?
Inexact is a save battery method, but it is... inexact.
AlarmManager have a problem, if the device is in sleep mode, the intent not start. You should use WakefulBroadCast.
https://developer.android.com/reference/android/support/v4/content/WakefulBroadcastReceiver.html
Try this..
alarmManager.setRepeating(AlarmManager.RTC, calendar.getTimeInMillis(), selectedTimeMiliseconds, alarmIntent);
I want to deliver timed notifications (everyday, 5:00AM), and tried to do this using AlarmManager with the following code:
Intent appIntent = new Intent(this, NotificationService.class);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
PendingIntent penIntent = PendingIntent.getService(this, 0,
appIntent, 0);
alarmManager.cancel(penIntent);
Calendar cal = Calendar.getInstance();
cal.set(Calendar.HOUR_OF_DAY, 5);
cal.set(Calendar.MINUTE, 00);
cal.set(Calendar.SECOND, 00);
alarmManager.setRepeating(AlarmManager.RTC, cal.getTimeInMillis(), AlarmManager.INTERVAL_DAY, penIntent);
The NotificationService.class looks (at least the important parts) like this:
int id = 001;
NotificationManager mNotifyMng = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
MainActivity.this).setSmallIcon(R.drawable.icon).setContentTitle("Test")
.setContentText("Test!");
mNotifyMng.notify(id, mBuilder.build());
stopSelf();
I can't seem to get it to work. When I set the emulator clock to 4:59 or something and wait for it to change to 5:00, there is no notification showing up and I can't figure another way to test it.
I hope you know some way to test it or find the bug in my code.
I believe the problem is that you cancel the PendingIntent but then you need to recreate it again before setting alarmManager.
//cancel pendingIntent
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
PendingIntent penIntent = PendingIntent.getService(this, 0,appIntent, 0);
alarmManager.cancel(penIntent);
//reset pendingIntent
Intent appIntent = new Intent(this, NotificationService.class);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
PendingIntent penIntent = PendingIntent.getService(this, 0,appIntent, 0);
Calendar cal = Calendar.getInstance();
cal.set(Calendar.HOUR_OF_DAY, 5);
cal.set(Calendar.MINUTE, 00);
cal.set(Calendar.SECOND, 00);
alarmManager.setRepeating(AlarmManager.RTC, cal.getTimeInMillis(),
AlarmManager.INTERVAL_DAY, penIntent);
To cancel a PendingIntent you need to create it exactly as you did the first time then call AlarmManagers cancel() on it as you are. But then you need to create it again to set the alarm on the PendingIntent
**I hope you know some way to test...
There may be a better way but, for testing purposes, I will sometimes set a global debug flag which will change times between testing and production. So say 4 hours might be 2 minutes. Times of the day may be a little more tricky but you can change the time to whatever hour, minute, or whatever is close. Once you know it is triggering at the right time then you can change it back and still test when that time of day comes around but you now know it should be working.
