Hi, I test the example and works ok.
Then I add the same modules to my firts B4Xpages app.
Modify the manifest and add the #Aditionaljar
Compile, run and when I press the barcode button , which
B4XPages.ShowPage("BarcodePage")
I get this error:

Call B4XPages.GetManager.LogEvents = True to enable logging B4XPages events.
** Activity (splash) Resume **
java.lang.Exception: Sub activity_permissionresult was not found.

You should use the comment link zipper to create the zip file, at the top of B4XMainPage.

NEVER write:

Activity.Finish
This is the splash screen implementation. It is not the B4XPages activity.

1. The error message in the screenshot is different than the error you posted.
2. I've ran your project and it works fine here.

I have a feeling that you are using an old version of RuntimePermissions. Maybe you updated it at some point and it wasn't overwritten when a new version was installed.
Check the date of RuntimePermissions.jar in the internal libraries folder. It should be from June 2020.

Weird is that the example works ok using my actual RuntimePermissions

Error in my app is when I click on the start button to start scan.

Send me your PC & smartphone, by drone 😄 :(:(:(

Open the project; "open" mBarcode B4XPage. There should be:
B4X:
Sub Class_Globals
'...
'...
#if B4A
Private rp As RuntimePermissions

and

B4X:
#if B4A
Private Sub StartCamera
    rp.CheckAndRequest(rp.PERMISSION_CAMERA)
    Wait For B4XPage_PermissionResult (Permission As String, Result As Boolean)

Is it so?
