Android Question Kiosk Mode stopped working

[iCAB]

Hi Guys

I was testing the code below few weeks ago and I am sure it was all working fine:
https://www.b4x.com/android/forum/threads/device-owner-tasklock-kiosk-apps-2017.81765/

I am trying it today and I am running into some issues.

Please see log

Any ideas what could be wrong?

Do you really have a kiosk app b4a.example?
You are maybe overwriting it by any example found? Usually it is this packagename

Hi Don
Thanks for your reply.
I just recompiled with a different package name and got the same error

Have you added the manifest editor code?

Hi Erel
I downloaded the project and used it as is.

 

[Erel]

What if your Administrator library version?
Which version of B4A are you using?

 

[iCAB]

Administrator library version: 1.10
B4A: 9.50

 

[Erel]

It is a mistake not to use the latest version of B4A.
As you changed the package name you should also change it in the adb shell command.

Thanks Erel, I will give it a try
