Android Question repeat alarm

[f0raster0]

Hi Team,

I'm trying to set up an alarm that will repeat every 7 days based on this example:

Start receiver at exact time

The standard StartReceiverAt is inexact, in order to allow the OS to make optimizations. Worth reading: https://developer.android.com/training/scheduling/alarms Exact scheduling: 1. AddPermission(android.permission.SCHEDULE_EXACT_ALARM) 2. Private ion As Object - class global 3. Private...

Is this code correct? thanks in advance

Private Sub Button2_Click
    Wait For (GetScheduleExactAlarmPermission) Complete (HasPermission As Boolean)
    if HasPermission Then
        StartServiceAtExact(ScheduledReceiver, DateTime.Now + 7 * DateTime.TicksPerDay, True) ' Schedule for 7 days later
    Else
        Log("no permission")
    End If
End Sub

Edit: What is needed to repeatthis alarm every 7 days?

you already saw @asales' example: https://www.b4x.com/android/forum/threads/receiver-set-a-repeating-alarm.158157/#content
when the service starts, it sets itself to start again. more important, the example uses a foreground service. both are needed to keep your project running "forever".

technically, it is possible to have the os wake you repeatedly every 7 days to run some job, but i don't think i've seen that implemented in b4a. we use the "self-restart" method show in the example and elsewhere.

if you use a receiver, keep in mind it cannot run a long job. the os will kill it. it would need to run a service. if you started the project with a foreground service, then you've already dealt with half the problem.
