Hi,

I have (had?) a working project and, after updating to b4a 9.30, I'm getting an error at the Activity.LoadLayout clause, at the Activity_Create event.

Reading the logs I think it had to do with the toolbar and the B4XProgressBar and some compatibility stuff, but I don't understand what. I've deleted the view and added it again, cleaned the project... but the error stays.

I have and extend and additionalres; I paste them because they're relevant:

B4X:
#Extends: android.support.v7.app.AppCompatActivity
#AdditionalRes: D:\Android\SDK\extras\google\google_play_services\libproject\google-play-services_lib\res, com.google.android.gms

And, the log:
B4X:
--------- beginning of system
--------- beginning of main
** Activity (main) Create, isFirst = true **
Error occurred on line: 33 (B4XProgressBar)

Thank you!

Hi Erel, thank you for your answer!

No; that exapmple doesn't work. I'm pasting the logs:

No, I think I didn't... Now I did, but I'm getting the following error:

B4X:
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
Error occurred on line: 129 (Main)

** Activity (main) Resume **

The line referenced is:
B4X:
ToolbarHelper.ShowUpIndicator = True

ToolbarHelper is an ACActionBar type object.
If I comment the ToolbarHelper lines, the app runs but it looks weird (the top bar is missing)

Thank you very much.

Hi Erel, thank you for your answer, again.

No, I'm not getting that error in that example.

After a detailed comparison, I've found it had to do with the "use as main actionbar" property of the toolbar, which was disabled and It has to be enabled... right?

I don't understand if it was always the case, because I've never opened the layout since I've started to use v9.30. It's a new property? Is there a new restriction regarding that property?

Regards!
