Alexander Stolte Expert Licensed User Longtime User May 4, 2024 #2 And what kind of notifications? Local notifications or sent from a server? Upvote 0
Alexander Stolte Expert Licensed User Longtime User May 4, 2024 #3 B4X Push Server B4X Push Server is a B4J written back-end server for B4i and B4A apps that use push notifications (Android - GCM, iOS - APN). Its two main features are: - Collect device tokens - DeviceToken class. - Send messages to the devices - Send servlet (which calls iOSPush and AndroidPush modules)... www.b4x.com But Firebase seems to be the only way forward in B4I 2024.

The best you can do is to implement a "background fetch" feature and show a local notification. You will not have real control over the timing of the notifications. Upvote 0

voxel Active Member Licensed User May 5, 2024 #6 Do you have a code example for using a local notification? and an example of background fetch? Can I use this example? https://www.b4x.com/android/forum/threads/background-fetch-downloads.56022/page-2 Can I trigger a task in the background every day at 12 p.m. and then trigger a local notification? Why won't I be able to control the start time of notifications? Thank Upvote 0

Half a year ago I tried to develop an alarm clock with B4I, but the app was always killed by the OS without having an extended time. Does not work: How to use the BGTaskScheduler I would like to create an alarm clock app and have found apps in the app store that do exactly what I want to achieve. e.g. ring in 8 hours, the apps regulate the volume in the background of the music that is then played -> so the app has to run in the background.

This should be done with a scheduled local notification. There is no other way. voxel said: Why won't I be able to control the start time of notifications? Click to expand... With background fetch the OS will start the process from time to time. You have no control over the exact time. Note that background fetch actually starts your app. Local notification doesn't.
