Android Question services: strange messages

[Roberto P.]

I still have problems with the operation of the services, which do not always start at the established intervals.

I set the start every 5 minutes

    StartServiceAt("", DateTime.Now + 5 * DateTime.TicksPerMinute, True)

these messages are displayed occasionally:

No partial wakelock.
** Service (starter) Destroy (ignored)**
** Receiver (starter) OnReceive **
The Starter service should never be started from a receiver.
*** Service (starter) Create ***

someone can help me understand what it can be

thank in advance

I set the start every 5 minutes

Android will not allow you to run a service in so such short intervals! Set it to 30 minutes or more.
Additionally you need to inform about services in android 8 and above.

thank Manfred

I read the post about services in Android 8, and At this point I ask for help to correctly create a service that remains always active, which starts every 5 minutes or less, which works from version 6 of Android up to 8.01.

thank in advance

You shouldn't use StartServiceAt with the starter service. Use a different service.

Always running service that works on all versions of Android: Background location tracking

Hi Erel,
this is the implementation:

- I've Starter Service
- I've Sync Service

- StartService run Sync service:

Sub Service_Start (StartingIntent As Intent)
....
StartService(SSync)

- SyncService have the startAt timer

Sub Service_Start (StartingIntent As Intent)
...
StartServiceAt("", DateTime.Now + 5 * DateTime.TicksPerMinute, True)

' this is try for not terminate the service
Service.AutomaticForegroundMode =  Service.AUTOMATIC_FOREGROUND_ALWAYS

there is somethings wrong?

thank

Based on the warning message you are starting the starter service from a receiver. This is a mistake. It doesn't happen in the code you posted.

there is somethings wrong?

Yes, newer versions of Android will not let you schedule the app to start every 5 minutes.

so what can be caused by an error?

Yes, newer versions of Android will not let you schedule the app to start every 5 minutes.

what is the minimum time?

what is the minimum time?

30 minutes or more i think

You can use a always running service as an alternative. No need to restart anything.
