Android Question Activity Recognition Detection

[roncoa]

I am trying the ActivityRecognition.zip file in this thread https://www.b4x.com/android/forum/threads/physical-activity-recognition-detection.42481/ ,but this code is never fired.

    For Each ev As TransitionEvent In Starter.client.GetTransitionEvents(StartingIntent)
        Log(ev) 'ignore
        ToastMessageShow("" & ev, True)
    Next
    Service.StopAutomaticForeground

I am attaching an image with the log.
Is it correct that the class shows 'v1.00' and not 'v3.00'?

Thanks

Yes, that's the correct code.

I've just tested it on an Android 11 device and it works properly. I tested it outdoors and the detection doesn't happen immediately.

These are the logs:
*** Service (starter) Create ***
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
** Activity (main) Pause, UserClosed = false **
sending message to waiting queue (activity_permissionresult)
running waiting messages (1)
** Activity (main) Resume **
true <-------------------------------------------------------------------- do you see this one?
** Receiver (recognitionservice) OnReceive **
*** Service (recognitionservice) Create ***
** Service (recognitionservice) Start **

[ActivityType=WALKING, ElapsedTime=401678140000000, IsInitialized=true
, TransitionType=ENTER]
** Receiver (recognitionservice) OnReceive **
** Service (recognitionservice) Start **

[ActivityType=STILL, ElapsedTime=401707031000000, IsInitialized=true
, TransitionType=ENTER]

It only worked fine the first time I loaded the app with B4A.
From the second time, in the log I only see "true" without "ActivityType = ....."

From the second upload :

*** Service (starter) Create ***
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
true
** Activity (main) Pause, UserClosed = false **
** Service (starter) Destroy (ignored)**
** Activity (main) Resume **
** Activity (main) Pause, UserClosed = false **

I have always successfully used the old method, which allowed to set a detection interval and to have a confidence value.

How can I get these 2 features?

Possibly, is there any contraindication to using the old method?

You should first get it working.

No. The old API is no longer supported.

Based on the logs, it looks like the code is correct. Make sure to test it in release mode. Try to restart the device and see if it helps.

Thanks.
After rebooting, everything seems to be working.

You should first get it working.

Is it possible to set a detection interval or have a confidence value?
Or something similar?

 

[Erel]

I don't see such options in the native API.

 

[roncoa]

I got it all working, thank you very much.
I just have one more question.
How can I "force" the status update, or "reset" it in order to have the current "Recognition_state"?
For example, if I start the app and the phone is in STILL-ENTER, I will not have updates until the status changes to STILL-EXIT and then to the new status. I would like to have STILL-ENTER (or any other status) on demand.

Thanks again

 

[Erel]

As far as I see it is not possible to get the current state.
