Android Question Trying to pass data from service to Main activity.

[microbox]

Hi everyone.... I have a service module (SMS receiver) and once I have the right data I need it to pass it the Main activity.
Code in the service module.

Sub ReceiverMobile(str As String)
    CallSubDelayed2(Main,"MobileUpdate",str)
End Sub

Code in the Main

Public Sub MobileUpdate(mbile As String)
    Log("in the Main Activity ")
    DBUtils.ExecuteMap(SQL, "Update profile set mobile = '"& mbile & "'",Null)
    Log("Profile mobile updated! " & mbile)
End Sub

Sorry if this is easy but I can't make it work.

You neglected to say what exactly is not working. Are you not seeing the log statements? Is the app running in debug, release, obfuscated? We'll need a little more info to help you. If you're running obfuscated, try adding an underscore to the sub name and call (e.g. "Mobile_Update") and see if that fixes it.

I would recommend adding a log statement in your service before and after your CallDubDelayed2 to main to be sure the service is actually calling it.

It's correct!

The code has not issue. Are you sure that you are getting data inside the ReceiverMobile function?

Thanks everyone for giving the time. Yes I'm getting the data within the Receiver function.
This is the log output when a message arrived.

[Address=+63977131xxx, Body=Testing number #+639994421xxx testing, IsInitialized=false

Code that receives the message

Sub Service_Start(startingIntent As Intent)
    Service.StartForeground(1, notification1)
    servicerunning=True
    Log("MessageInterceptor Service Started")
    If startingIntent.Action = "android.provider.Telephony.SMS_RECEIVED" Then
        Dim MyValue() As String
        Dim messages As List
        Dim MessaGe,NewMobile  As String
        messages = ParseSmsIntent(startingIntent)
        For i = 0 To messages.Size - 1
            Log(">:"& messages.get(i))
            MessaGe = messages.get(i)
        Next
        Dim startx As Int
        Log(MessaGe)
        startx = MessaGe.IndexOf("#")
        NewMobile = MessaGe.SubString2(startx+1,(startx+1) + 13)
        Log(NewMobile)
        ReceiverMobile(NewMobile) '-----pass it to a function

    End If
End Sub

I can pass it to another service module but can not in the Main activity.

You can always save the message to a text file and play it in any activity

The activity will not be started if the app is in the background.
You can start it yourself, however it is not recommended and will not work on Android 10+.

The correct way to notify the user is with a notification.

The activity will not be started if the app is in the background.

CallSubDelayed2(Main, "RoutineName", Data) should start the Main...

will not work on Android 10+.

no more on Android 10+?

 

[Erel]

CallSubDelayed2(Main, "RoutineName", Data) should start the Main...

Only if there is a visible activity: Using CallSubDelayed to interact between activities and services

Android 10+ restriction is not related to CallSubDelayed. It is related to calling StartActivity from services: https://www.b4x.com/android/forum/threads/startactivity-from-service.108771/#post-682671
