Open Source • Background Tasks: Itoo 🚀

[Jimis]

Thanks !

[SlowBro]

Oh I see, thank you, I was following an example from a different discussion. If I may ask as well, can itoo fetch a local variable in other procedures from another procedure if it is stored in itoo? Thanks.

@SlowBro

can itoo fetch a local variable in other procedures from another procedure if it is stored in itoo?

Use StoreProperty/FetchProperty methods

Trying To Show Latitude & Longitude Why Showing 0 0

@Saheb_Kole

Why Showing 0 0

Because at the time you are creating the process you did not get a gps signal

Also what is localhost124?

Generally to get location data in the background requires background licatuon permission. The locationservice extension is able to do it App Inventor Extensions: Location Service | Pura Vida Apps

@Randal_Andress

event failure in the service process with the PhoneCall component's PhoneCallStarted and PhonecallEnded events.

Can you elaborate on this?
What would you expect to happen?
Status is always unknown because unknown is a static text in your procedure

EDIT: do you expect to get both evemts twice (one from the background, the other from the foreground?
what do you get if you deactivate the 2 phone call events (foreground)?

For a more useful test let me suggest to do a background test, close the app and use the Notifier Loginfo method for debgging and check the log using logcat

Capturing Device Logs using adb logcat

ADB is a command-line utility that that can be used to control your device over USB from a computer. It will allow you to install / uninstall and or view logs on your device. This could be very handy when there are issues with a specific app and you like to view the logs for information that may lead to identify the cause of error. In this post, we’ll discuss how to install and use ADB. Installation: ADB comes with Android SDK. However, you can download ONLY the ADB files from HERE . EDIT: …

@Taifun

Thank you for you helpful comments and questions - And I am sorry that I just noticed your post yesterday

@Taifun

Can you elaborate on this?
What would you expect to happen?

First of all, I apologize for this sloppy example/case. It was based on a test case that contained two Player components: one in the UI and another in the Itoo process. I suppose I was attempting to show that the UI Player PhoneCall events responded to a phone call but the Itoo events did not...

I would have expected the PhoneCall events that were registered in the Itoo process to respond to the call and not the UI built-in blocks...however because of how it actually behaved (the UI built-in events responded in place of the itoo registered events, it was confusing..

@Taifun

Status is always unknown because unknown is a static text in your procedure

Yes - another sloppy job on my part... Because the text block "Join" would not accept the "status" variable, rather than solving that problem, I just put in the "constant" value... I have now decoded status using this procdure/function:

The version I am posting below is (hopefully) more useful and easier to understand.

...
what do you get if you deactivate the 2 phone call events (foreground)?

I have done separate tests for both of these variations. In all tests the app was started, then the player started, then a phone call was made but not answered - caller hangs up. Here is a brief description and summary of results.:

1. With both sets of events present in the code (as posted here), logcat was captured for two cases:
   a) UI remained active/visible: the UI event blocks responded to the call/hang-up:
   ItooMusic_orig_PhoneCall_posted2-UIactive-both.txt (490 Bytes)
   b) UI was exited: no PhoneCall event was called:
   ItooMusic_orig_PhoneCall_posted2-exitUI-both.txt (147 Bytes)
2. With the standard PhoneCall event blocks disabled in the UI/foreground code, logcat was captured for two cases but no PhoneCall events were called in either case:
   a) One with the UI remaining active:
   ItooMusic_orig_PhoneCall_posted2-UIactive-X.txt (228 Bytes)
   and
   b) the other having exited the UI:
   ItooMusic_orig_PhoneCall_posted2-exitUI-X.txt (228 Bytes)

It appears that somehow the Itoo registered events are not being associated with the player running in the Itoo process - they are not called in any of the test...OR perhaps the player is not actually running in the Itoo process???

Are the process/thread ids from the logcat output of any use in determining this? Any test I can do to gather more information?

@Randal_Andress

b) UI was exited: no PhoneCall event was called

the PhoneCall component was not written to be running while the app is in the background...
as you can see the phone state listener will be unregistered while closing the app, see the sources here appinventor-sources/appinventor/components/src/com/google/appinventor/components/runtime/PhoneCall.java at master · mit-cml/appinventor-sources · GitHub

@Override
  public void onDestroy() {
    unregisterCallStateMonitor();
  }

let me invite you to test my new phone state listener extension which keeps running while the app is in the background... I will send you a PM soon...

why doesnt the "notifictation" get called when i the clouddb data does change?, the process runs fine but the notification doesnt work

[Taifun]

Did you ask for post notifications permission?
Taifun

[Krx_asy]

Yes

[Kumaraswamy]

TinyDB does not work with Itoo, please use Itoo's own Store/Fetch property blocks.

[Krx_asy]

i removed it , but still doesnt work

[Kumaraswamy]

Why are you passing a random integer to code? It must be 2.

Try the example in the first post:

@Kumaraswamy

CloudDB with Itoo, update data every few seconds

[Krx_asy]

i did already try 2 before the random integer, but it still doesnt work

[Kumaraswamy]

oh i found my error, i tested my app by building it to an apk and another i tried from companion. But when i tried it on another phone the notification now happens, thankyou

[Krx_asy]

i have this code setup, why doesnt the notif work after closing my app? i turned off battery optimization already(and the itoo notification does show up but the firebaseDB datachanged doesnt work i think). When i reopen my app the notification shows again

[TIMAI2]

Are you asking for the permission ?

[Krx_asy]

Yes, and I accepted it
