Android Question How to add a Starter service to an existing project?

[agraham]

I want to add a Starter service to an old rather large project that originated before the Starter service existed and thought that I could just add an existing Starter.bas module to the project as a module and all would be well. But it's not! I get an "Unable to create service" error when I run it. What am I missing?

Make sure to add it as a Service module. It should work.

I can't get it to work by either of the methods below.

I first tried adding an existing Service.bas by Project -> Add Existing Modules

I then tried Project -> Add New Module -> Service module and named it Starter

It should work. The problem is somewhere else. Run in Release mode and post the error message.

Found it deep in the "very" long error log.

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.CharSequence anywheresoftware.b4a.objects.ActivityWrapper.getTitle()' on a null object reference

Sub Process_Globals
    ' ...
    Dim DefaulTitle As String = Activity.Title & " v" & NumberFormat2(Version, 1, 2, 2, False)
    ' ...
End Sub

That's been working for years now!

There should be a warning on this line...

One of the problems that B4XPages solves (I understand, anyway, that having an old project...!)

I can't wait to become very expert with B4XPages!

 

[agraham]

Nope, no warning and there's nothing on the #IgnoreWarnings: line

No it's not.

No it's not.

Sub Process_Globals ' ... Dim DefaulTitle As String = Activity.Title

Yes, I thought it was a different Activity, you're right.

B4XPages is a bit related as you no longer have two global subs, with different behavior.
