Alarm Manager with Itoo

[Mario1]

As indicated by Taifun

@Taifun

Your solution drains the battery heavily... as you set it up, your process checks each second, if the alarm time occurred to then display a notification... even if you do this check only each minute or each hour, you need a process running to check the time. Actually this is like abusing the Android system. A real alarmmanager gets triggered from the Android operation system at the alarm time and then displays the notifiation.

Indeed, if a new alarm is checked every second, it would be very costly for the system.

I have modified this aspect and now the Timer has an interval equal to the time to the next alarm, which could be 10 seconds or 3 days, so the system is released and there is no problem of forcing it

If the next alarm is in 5 hours and 10 minutes, that would be the Timer interval

For this I have made the following modifications in the aia

alarm procedure

As can be seen when the service starts, the Timer has an interval equal to the time we have in the database to which we add the system time (all in milliseconds)

data procedure

When the Timer verifies that there is a new alarm, it does everything indicated in the first post and also sets its interval to 1 second, in order to receive the response of the activity for which the alarm has already arrived.

Once the service receives this response, if there is a new alarm, it sets the timer interval to the time left for the new alarm. If there were no more alarms, it would turn off the service.

First of all I congratulate you on your alarm manager using the Itoo service. But I ask you a curiosity of mine; How did you make the TimePicker prettier than the traditional one?
Greetings

How did you make the TimePicker prettier than the traditional one?

He used Theme "Device default" instead of "Classic".

@Mario1 , how can I check your other tutorials?

The strange thing is that now, even though I keep trying to change the TimePicker theme from Classic to default device; I am irremediably left with the classic theme

How can I make that after a while the player stops itselfs?
Or not loops forever.

Hello and thanks for your awesome work - I'm a beginner I tried to download your work and opening with the simulator displays the home screen then there was this error - I tried to install on XIAOMI Redmi Note 13 with Android 15 AQ3A and launching the program presents a white screen with nothing else - Am I making mistakes? Can you help me? Thanks for your time

Est il possible d'ajouter un texte dans la ListeWiew, en plus de l'heure de déclanchement de l'alarme, pour indiquer ce qu'il y aurait à faire au déclanchement d'alarme, par exemple "anniversaire de..."ou "fête de... " Ou "rendez-vous à..." etc.
Et surtout, pouvez vous me donner une direction à prendre pour modifier votre .aia pour réaliser ce genre de renseignement d'alarme, si c'est possible ?

You probably have overseen my comments from here

Alarm Manager with Itoo

Thank you @Mario1 for the tutorial, as we can see you know how to work with Itoo, you created an impressive example! However there are 2 major disadvantages of your solution compared to a real alarmmanager like [PAID] Alarm Manager Extension with Notification or Autostart : Your solution needs to display a persistent notification in the notification bar as it uses forground service. A real alarmmanager runs without that. Your solution drains the battery heavily... as you set it up, your…

The example by Mario is not really made to be kept running for several days.

@Mario1

To set an alarm, as you say, an extension that uses android.app.AlarmManager is better, but it could work perfectly for a short timer.

Let me recommend you to use a real alarmmanager for those purposes
There is a free alarmmanager available, which offers basic functionality (do a search in the community) and there is my paid alarmmanager available, which offers additionally advanced functionality.

App Inventor Extensions: Alarm Manager | Pura Vida Apps

Both can display a notification message of your choice. You have to set the message while defining the alarm. My alarmmanager additionally is able to dynamically set the message at alarm time among other things.

@Taifun

Il existe un gestionnaire d'alarmes gratuit disponible, qui offre des fonctionnalités de base (faites une recherche dans la communauté)

Merci Taifun
J'ai fait cette recherche qui ne m'as malheureusement pas conduit à ce que vous me proposez , je n'ai pas dû chercher comme il faut, dommage.
S'il vous plaît, pourriez vous mettre le lien de ce que vous me proposez, je vous en serais reconnaissant

I believe Taifun is referring to this extension:

[FREE] Alarm Extension

After having published a first extension and after what was commented by the leading users, about what had to change in the extension, I published it again with the recommended changes. The extension now complies with the nomeclature instructions indicated in I also try to adapt it to what is indicated in Is it novel? Has your type of extension been done before by other extension developers. Do we really need it again? What is different/unique about it, when compared with the other simil…

@Kumaraswamy

Je crois que Taifun fait référence à cette extension :

Après avoir publié une première extension et suite aux commentaires des principaux utilisateurs concernant les modifications à apporter, je l'ai republiée en intégrant les changements recommandés. L'extension respecte désormais les consignes de nomenclature indiquées. J'essaie également de l'adapter aux recommandations. Est-elle novatrice ? D'autres développeurs ont-ils déjà créé des extensions similaires ? En avons-nous réellement besoin ? Qu'est-ce qui la distingue des autres extensions similaires ?

Merci oui je le penses merci des conseils
