Android Question B4A Kiosk Mode (2017)

Magma · Nov 30, 2017

Hi there..

following the tutorial and help from Erel - read here:
https://www.b4x.com/android/forum/threads/device-owner-tasklock-kiosk-apps-2017.81765/

at step 2:

2. Connect the device to the PC in USB debug mode. Open command line and run the following command:
Replace your.package.name.here with the correct package name.

adb shell dpm set-device-owner mvt.client/anywheresoftware.b4a.objects.AdminReceiver2

mvt.client is the name of my package...

but getting the following message:

/system/bin/sh: dpm: not found

why ?

Are you using atleast lollipop? As far as I know, dpm is only available since lollipop.

Starting from Android 5 (API 21) there is better support for kiosk applications.

@DonManfred can i use the old way for kiosk mode - what's the difference ?

https://www.b4x.com/android/forum/threads/android-kiosk-mode-tutorial.10839/

...Is it better (possible) to use two ways and user (installer) select the way at a setup screen ?

I dont know. I never need a KIOSK app.
As far as i know in the old Kiosk solution the user was able to go into the settings.
I dont know anything about a difference.

you can not setup a Kiosk app using a standard installer. You need to use ADB commands to setup the Provision. See Kiosk tutorial!

@DonManfred Thanks for answerss

you can not setup a Kiosk app using a standard installer. You need to use ADB commands to setup the Provision. See Kiosk tutorial!

I know... that's because the error...

But i will provide a guide about installation at the installer-guy !

Before close the topic...

At the Erel 1st post:
https://www.b4x.com/android/forum/threads/device-owner-tasklock-kiosk-apps-2017.81765/

Says:

Existing user accounts on the device must first be removed (Settings - Accounts).

We are talking about adminstrator accounts?... because that option is on some tablets Settings->Security->Administrators

We are talking about accounts on Facebook, Google ?

or we are talking about Administrator Users - because already delete them and tried again the command (ofcourse in Android 5+) - got that:

D:\Project-MVT\adb>adb shell dpm set-device-owner mvt.client/anywheresoftware.b4
a.objects.AdminReceiver2

java.lang.IllegalStateException: Trying to set device owner but device is alread
y provisioned.

at com.android.internal.os.RuntimeInit.nativeFinishInit(Native Method)
at com.android.internal.os.RuntimeInit.main(RuntimeInit.java:257)

WHAT option exactly means Erel (from the post i can understand that means the option got accounts for Facebook, Google etc)... ?

ps: hope not need root device...

DonManfred · Dec 2, 2017

Check the Error: Trying to set device owner but device is already provisioned.

You can not add a provision twice.

Magma · Dec 2, 2017

@DonManfred ... is provisioned to other app ? because i ve never run the same command...?

How i can check where provisioned ?

Erel · Dec 3, 2017

See the tutorial. The real kiosk mode is only supported on Android 5+.

For any other question you should start a new thread.

Magma · Dec 4, 2017

@Erel but now i was talking about Android 5+ device (java.lang.IllegalStateException: Trying to set device owner but device is already provisioned.)

starting new thread...
