Android Question Can't find what cause this error in my service

[jtare]

Reading in the Google Play Store Console some of my users are having issues with a background service, but I can't replicate it, I don't know what is causing it. For what I can guess, the error occurs when the service is starting or creating, and the java line where it crashes is not something that I wrote on b4a but something b4a adds when compiling I think.

This are the errors:
1)

            if (intent != null)
                in.putExtra("b4a_internal_intent", intent);
            context.startService(in); 'THIS IS LINE 16
        }

    }
.......

JAVA LINE 68

.........

                handleStart(intent);
            }}))
            ;
............

This is how I start the service under Activity_resume (main activity)

    If IsPaused(connectionService) Then
        Try
            Log("Connecting")
            StartService(connectionService)
        Catch
        End Try
    Else
        Try
            Dim isConnected As Boolean = CallSub(connectionService,"isConnected")
            If Not(isConnected) Then
                Try
                    StartService(connectionService)
                Catch
                End Try
            Else
                Log("Is already connected")
            End If
        Catch
            Log(LastException)
        End Try
    End If

I'm running B4A v7.3, thats why I don't use crashlytics.
The devices that sent this errors are all running Android 8.
The first 2 errors were sent by a Mate 10 lite (HWRNE)
The third one was sent by a moto g(6) play (aljeter)
I ran the app in the simulator with Android 8 but no crashes happened.

If more information is needed please let me know.

I'll appreciate your help or suggestions. Thanks in advance.

See this important tutorial: https://www.b4x.com/android/forum/threads/87610/#content

You must use B4A v8+ with the automatic foreground feature (v8.3 is recommended as it simplifies the life cycle of the starter service).

Thanks, I'll upgrade.
