Android Question SOLVED: Kiosk Mode B4A v12.80 (64bit) - Error: Unfortunately App has stopped

[FrancescoS]

Hi everyone,
I am testing the original kiosk mode example.

Android "Kiosk mode" tutorial

Edit: A better kiosk implementation is available: https://www.b4x.com/android/forum/threads/device-owner-tasklock-kiosk-apps-2017.81765/#post-518018 Kiosk mode applications are applications that lock the device and do not allow the user to run any other application other than the kiosk...

www.b4x.com

I have compiled and run it on an android 4.4.4 tablet, first time works ok.
If I then press the button on the tablet that returns me to the desktop, when the Kiosk service tries to run the app again, I get the error:
"sorry - Unfortunately Kiosk App has stopped"
can anyone help me ? thanks.

B4A v 12.80
Android v4.4.4
Jdk 14.0.1
resources 11_22

Caused by: java.lang.RuntimeException: java.lang.RuntimeException: Cannot change properties after call to SetInfo. Initialize the notification again.

This is a simple one. Check the code that creates a notification. The call to Notification.SetInfo should be the last one (before showing it).

Thanks Erel, SOLVED !

original code:

Sub Service_Create
    pe.Initialize("pe")
    If Notification.IsInitialized = False Then
        Notification.Initialize
        Notification.Icon = "icon"
        Notification.SetInfo("Kiosk app", "Kiosk app", Main)
        Notification.Sound = False
        Notification.Vibrate = False
    End If
    Timer1.Initialize("Timer1", 300)
End Sub

corrected code:

Sub Service_Create
    pe.Initialize("pe")
    If Notification.IsInitialized = False Then
        Notification.Initialize
        Notification.Icon = "icon"
        Notification.Sound = False
        Notification.Vibrate = False
        Notification.SetInfo("Kiosk app", "Kiosk app", Main)
    End If
    Timer1.Initialize("Timer1", 300)
End Sub
