calendar.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY);
calendar.set(Calendar.HOUR_OF_DAY, 1);
PendingIntent pi = PendingIntent.getService(context, 0, new Intent(context,MyClass.class),PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 7*24*60*60*1000, pi);
I have this simple pending repeating alarm and it works just fine only when system android alarm is not set up. It doesnt matter on what time alarms are set in system Alarm app, looks like this system app stops all my pending intents. Any idea how to debug this? What can cause this problem ?
I would like to use it in paralel with system alarms.
make sure you have permission
<uses-permission android:name="com.android.alarm.permission.SET_ALARM" />
For Debugging:
override onNewIntent() in your activity MyClass Activity like this:
#Override
onNewIntent(Intent intent){
android.os.Debug.waitForDebugger();
if(intent.hasExtra("alarm")){ //Put a break point here
Log.d("Alarm fired","yes");
}
}
Create you PendingIntent for firing alarm like this:
Intent intent=new Intent(context,MyClass.class);
intent.putExtra("alarm","yes");
PendingIntent pi = PendingIntent.getService(context, 0, intent,0);
So, when your alarm gets fired, control will come to onNewIntent and wait for you to attach a debugger. That time go to Attach debugger button in android studio and attach debugger to your application. And this is how you will know that you alarm has been fired.

I'm developing Reminder application.It works fine until I reboot or forcefully stop.I have used both the actions in Manifest: BOOT_COMPLETED and QUICKBOOT_POWERON
and also added the RECEIVE_BOOT_COMPLETED permission, still, my broadcast receiver is not working. Is there any way to solve this issue and to check that forcefully stop is called or not on android through the program.
Thanks in advance.
You can use AlarmManager to set an alarm to check if you are ok or not.
Here an example to set AlarmManager ;
private AlarmManager alarmMgr;
private PendingIntent alarmIntent;
...
alarmMgr =
(AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, AlarmReceiver.class);
alarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
alarmMgr.set(AlarmManager.ELAPSED_REALTIME_WAKEUP,
SystemClock.elapsedRealtime() +
60 * 1000, alarmIntent);
And in your BroadcastReceiver you need to set your alarm again. You can check your receiver every hour.
So even if your app is forced to stop, you have chance to restart when your alarmmanager checks it.
I am writing some code to fire alarm at a specific time. Everything is working fine and alarm is fired as expected.
But when I clear memory using some Memory Cleaner app, then the alarm is not fired.
I have added permissions and intent-filter for Boot Completion that set my alarm after device boot. But I don't know how to reset my alarm if any Memory Cleaner app cleans the memory?
Code for setting alarm
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.add(Calendar.SECOND, 10);
Intent intent = new Intent(context, DailyAlarmService.class);
PendingIntent pIntent = PendingIntent.getService(context, Constants.DAILY_ALARM_REQ_CODE, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager manager = (AlarmManager) context.getSystemService(context.ALARM_SERVICE);
manager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 5000, pIntent);
Thanks in Advance.
I am trying to set two alarms which will run two different background services. I set the alarm inside the onCreate method of my activity class. But the problem is that the service classes which are extending IntentService are not getting called, i.e. their method onHandleIntent() is not getting called. This is how I set my alarms
//Creating alarm for showing notifications.
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
//create an alarm for today if there is still time else schedule alarm for tomorrow.(Handled inside the one time alarm class).
//FIRST ALARM..............
Intent intent = new Intent(ActionBarTabActivity.this, ScheduleOneTimeAlarmForToday.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pendingIntent = PendingIntent.getService(this, 0, intent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
//SECOND ALARM.............
Intent i = new Intent(ActionBarTabActivity.this,RemoteNotificationService.class);
PendingIntent pi = PendingIntent.getService(getApplicationContext(), 111, i, 0);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(), 1000 * 60, pi);
I have declared the services inside the minifest file as below
<service android:name="com.nss.common.services.ScheduleOneTimeAlarmForToday" />
<service android:name="com.nss.common.services.RemoteNotificationService" />
Also the alarms run properly on my old samsung phone but when I test it on my new Asus Zenfone or any other new phone, it doesn't show up.
Edit:
My logcat shows this:
10-19 12:25:05.605 634-744/? V/AlarmManager﹕ triggered: flg=0x10000000 cmp=com.nss.zobbers/com.nss.common.services.ScheduleOneTimeAlarmForToday Pkg: com.nss.zobbers
10-19 12:25:06.846 634-744/? V/AlarmManager﹕ triggered: cmp=com.nss.zobbers/com.nss.common.services.RemoteNotificationService Pkg: com.nss.zobbers
So I don't get it, my alarm is triggered but the service it needs to call doesn't get called? I have tried many posts but couldn't find the error. Please help, thanks in advance.
I made it to work, but I won't accept it as my answer as maybe someone will tell the exact reason why it doesn't work. Well instead of directly calling services via alarmManager, I modified my code to call a broadcast receiver which then calls the respective service. Now it seems to work perfectly on different devices.
I set up an alarm for my PendingIntent. Now I want to show in my activity, if this alarm is set or not.
Intent service = new Intent(context, MyService.class);
PendingIntent pendingIntent = PendingIntent.getService(context, 0, service, 0);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, firstStart, interval, pendingIntent);
Is there any way to check is this alarm is set?
You can't query the AlarmManager to find out if the alarm is set. You pretty much need to remember yourself. You can store something in shared preferences to indicate that you set the alarm. However, once the phone is restarted your alarms are gone, so you also need to either reschedule the alarms on a reboot OR clear your preferences to indicate the alarm is no longer set.
Unfortunately, this is one of those things that Android really lacks (a way to query the alarmManager).
In my application i want to use alarm service for specific period of time.I'm taking start time and end time values from user and saving it in database,Now i want to start a alarm service at start time and alarm should go off at end time specified by user.I'm new to this topic and not able to understand how to implement this...Any help will be appreciated.Thank u..
This is how you implement an alarm manager. But you will need to read about Calendar object in android also.
String alarm = Context.ALARM_SERVICE;
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 8);//Just an example setting the alarm for the 8th hour of a day.
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND,0);
calendar.set(Calendar.MILLISECOND, 0);
AlarmManager am = (AlarmManager)getActivity().getSystemService(alarm);
//This is the intent that is launched when the alarm goes off.
Intent intent = new Intent("WAKE_UP");
PendingIntent sender = PendingIntent.getBroadcast(getActivity(), 0, intent, 0);
//If the user wants the alarm to repeat then use AlarmManager.setRepeating if they just want it one time use AlarmManager.set().
am.setRepeating(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis() , AlarmManager.INTERVAL_DAY, sender);
}
Also you will need to register a BroadCast Receiver to except the intent when the alarm sets it off.
You create the BroadCast reciever and register it in your manifest to receive the intent from the alarm.

Here is a great tutorial to help you understand better
The key is to use the AlarmManager with a pending intent.
mAlarmSender = PendingIntent.getService(AlarmService.this,
0, new Intent(AlarmService.this, AlarmService_Service.class), 0);
Then you create the AlarmManager from the current context:
AlarmManager am = (AlarmManager)getSystemService(ALARM_SERVICE);
And schedule the previously created pending intent.
am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
firstTime, 30*1000, mAlarmSender);
On schedule the AlarmService_Service service will be called, or you can put another intent like open a specific activity.
Here is the complete example of how you can schedule an alarm: AlarmService.java
