I want to start my application everyday at a particular fixed time.i tried the link
Start app at a specific time but didn't worked.
By use of AlarmManager you can declare the time. And use of BroadcastReceiver you can start the application at the time of reached. I suggest you to try Commonsware example application. There you should modify the code by yourself with your needs.
Hope this helps you lot.
You should achieve it using a service with AlarmManger for that.
First when user install your application then you should start Service then service start AlarmManager content a pendingIndent this pending intent fire on you specific time mention you in AlarmManager

I want to make something in a specific time period. For instance, I'll show a message in my application from 6pm to 8pm everyday. I'll do it in a service. Which code should I use and could you please give a sample? Thanks in advance...
I would look into using Android Notifications along with AlarmManager to handle the repeating.
Particularly setRepeating in AlarmManager to call the service and creating the actual Notification in the onReceive of your service.
You should use an AlarmManager

you can find tons of examples online
Hi I need to set AlarmManager to run a reminder for me to take medication. I need to repeat it by custom amount of days and custom amount of times to take in the day.
So is there an efficient way to set the AlarmManager or CommonsWare's Implementation of the AlarmManager to remind me "twice a day starting at 9AM for the next 5 days" to remind me to take medication? Pls advice and tnx in advance for any constructive help in sample code and in relevant tutorials.
I haven't looked into Mark's AlarmManager implementation, but there is no way, in general, to get the bare AlarmManager to do what you are trying to do. You can schedule a single alarm, at a specific time, or a repeating alarm, that repeats at fixed intervals. If you want something that handles complex schedules like the one you describe, you'll have to write or find code that does it.
You want to use a PendingIntent with the AlarmManager. The idea is to schedule the pendingIntent with the alarmManager, have that trigger an intentService or broadcast, setup another pendingIntent with the alarmManager for the next desired event. You want to keep in mind that you'll need the BOOT_RECEIVED permission in case the user reboots their device. I have complex scheduling in Audio Control and this is exactly what I do.
Here is a pretty decent tutorial of what I mean:
http://android-er.blogspot.com/2010/10/simple-example-of-alarm-service-using.html
You need to schedule an alarm to the next time you want to take the medicine - according to your algorithm (for example if its twice a day, and you got to the pending intent callback for the first time today, then schedule the next alarm to start after [6,7,8,9,10...] hours).
You will need to save both last time of the alarm launch and the user settings in shared prefs/file/DB.
You need to handle process down (android killed it or the device was rebooted). In the case of device reboot you should use the boot receiver to start your service, but you need to remember that from android 3.1 the user has to use at least one time the GUI in order for you to intercept the boot completed receiver. The boot completed receiver should look when was the last time that the alarm launched, and according to the user settings set the next alarm launch.
In the case of android killed your service, you will need to make research, i can't help here.
see example
I have a service and some activity for that , I want whole application will restart at specific time like (03:00 pm), do you know any way to to do this , so at 3AM , the whole app restart ?
thanks
You can use popular time based scheduler Cron found in unix/linux. by default it it is not active.need some hack inside. but i think you can use AlarmManager This is a system service.
AlarmManager myAlarmManager = Context.getSystemService(Context.ALARM_SERVICE).
And if you need to stay alive after system reboot . Then you have to schedule he alarm after the device reboots.And need to have the RECEIVE_BOOT_COMPLETED permission in your AndroidManifest.xml
I want to write reminder. What i need to use? Make service app or just standart app runing in background or another way?
Thanks for replys!
What I really liked about this question is you asked about the idea for the app that you want to implement. You didn't ask for code.
I would suggest that you should make an app which should have a broadcast receiver, but still it should have service that runs in background.
The service will check the current time with your reminder time. A broadcast receiver is required to listen to startup broadcast, because you need to start your app as soon as your handset starts.
Have a look at this.
Have a look at the AlarmManager. It allows you to schedule your application to be run at some point in the future.
I'm making an alarm clock of sorts, and I was wondering what the best way to start an activity at a certain time would be. Would it be using the broadcast service or...
You need to use AlarmManager to register an Intent that will fire at the specified time.
