I have loaded the TabStrip into my Additional libraries and added it to the designer

I get this error when I try to run the code that loads a layout to the strip

B4X:
#AdditionalJar: com.android.support:support-v4
the IDE doesn't recogise it
I am running verion 7.3 of B4A

B4X:
#AdditionalJar: com.android.support:support-v4

    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.

End Sub

    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.

I fixed it by putting the additionaljar line in the main activity. I was putting it in the activity where I use the tabstripviewer. BTW I love this view it's awesome
