Android Question how to set app as always active - don't pause when another app goes foreground

[vangogh]

My app has a counter, counting seconds

semplified code [cut]

Sub Process_Globals
    Dim tmrTimerIndirizzoIP As Timer
end sub

Sub Activity_Create(FirstTime As Boolean)
    tmrTimerIndirizzoIP.Initialize("tmrTimerIndirizzoIP", 1000)
    tmrTimerIndirizzoIP.Enabled=True
end sub

Sub Activity_Resume
    Log("RESUME")
end Sub

Sub Activity_Pause (UserClosed As Boolean)
    Log("IN PAUSA")
End Sub

Sub tmrTimerIndirizzoIP_Tick()
    Log(DateTime.Date(DateTime.now) & " tick")
end sub

if the app in sent in backgound, e.g I open a another app, or the screen saver is active, the app goes to sleep - freezing. the timer stops running
(the Activity_pause sub is colled)

and it resume counting when the app is in foregroud again
(the Activity_resume sub is called)

see attacked image: it's the log

I saw PhoneWakeState, but it does different things (?)

SO:
How can I set the app to continue running also if another app in in foregroud, also if the screen goes off?
I need that my app is always active and doing his job - NO pause

thank you

You can't have an "Activity" run in the background, but you can have a "Service" run in the background.

Here is a sample project on how to do that:

Background location tracking

Simple example of a foreground service that keeps the process running in the background. The current location is shown in the persistent notification. The app starts at boot and theoretically should run all the time. It also schedules itself to run with StartServiceAt. This can help in cases...

NOTE: Newer versions of Android have more restictions on what can run in the background.

Use B4XPages. It is never paused.

cool, thank you

How can I move my actual project to B4Xpages?

"Move"? You should create a new project, of type B4XPages, recover as much as possible from the other project and insert it into this new one.

If your project is large, this will not be very easy, especially if you are not familiar with B4XPages.
