package is working fine in debug mode but when i run it in release mode its not working fine

Dear devs,

It is about the kiosk_mode package. I want to programmatically set the password to lock the app, is it possible to implement it?

Many thanks,

Can be the Gradle plugin in kiosk_mode be updated? When trying to run the app I get this error:

The Android Gradle plugin supports only Kotlin Gradle plugin version 1.5.20 and higher.
The following dependencies do not satisfy the required version:
root project 'android' -> org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.50

Can you tell me how to enable this and directly launch locktask without user permission?

I've tried step by step guide to enable device owner using adb and set Receiver in AndroidManifest.xml like this :

    <receiver
        android:name="com.example.kiosk.AppAdminReceiver"
        android:label="kioskadmin"
        android:permission="android.permission.BIND_DEVICE_ADMIN">
        <meta-data
            android:name="android.app.device_admin"
            android:resource="@xml/device_admin_receiver" />
        <intent-filter>
            <action android:name="android.intent.action.DEVICE_ADMIN_ENABLED"/>
            <action android:name="android.intent.action.PROFILE_PROVISIONING_COMPLETE"/>
            <action android:name="android.intent.action.BOOT_COMPLETED"/>
        </intent-filter>
    </receiver>

Then i run this adb command :
adb shell dpm set-device-owner com.example.kiosk/.AppAdminReceiver

The adb resulted in success as shown below :
Success: Device owner set to package ComponentInfo{com.example.kiosk/com.example.kiosk.AppAdminReceiver} Active admin set to component {com.example.kiosk/com.example.kiosk.AppAdminReceiver}

But when i tried to run my app again and run startKioskMode(), it shows screen pin hint and user can exit the screen pinning by pressing back and overview button.

Any help would greatly appreciated..

Thank you.

You wrote that "Android doesn't allow subscribing to lock task mode changes".

Have you tried the Lifecycle callbacks?

It sounds like it is possible to be notified when the mode changes. Polling every 5sec seems unnecessary.

Do you have any options to disable screen unpinning when kiosk mode is active?

In the kiosk_mode package, you wrote:

Android only
All the methods in this section will throw FlutterMethodNotImplemented in iOS.

Start kiosk mode

Stop kiosk mode

But when I look at the code, the functions are also available for iOS. So please update the documentation :-)

please help to resolve it

In Android 9 kiosk mode is working fine but in Android 12 the app is pinned instead of going to kiosk mode. How can this issue be resolved?

Hello, Android says that a 'pinned' app can open another app.

However, after calling startKioskMode() and the app is fixed, when I try to open another app, a notification appears saying that to do this I need to hold down both buttons...

So how do I enter another application without having to remove kiosk mode? To open the application I am using DeviceApps

bool isInstalled = await DeviceApps.isAppInstalled( 'com.app.my');

if (isInstalled) {
       DeviceApps.openApp('br.app.my');
} else {
       // ignore: use_build_context_synchronously
       ScaffoldMessenger.of(context)
       .showSnackBar(const SnackBar(
       content: Text('App not found!'),
       ));

Thx!

I have an app written with flutter and using the kiosk package. Then I called startKioskMode() when app first launch. But it shows with a selection: No, thanks and Got it.
If I choose No thanks then the koisk mode is exit.

Below shows in https://pub.dev/packages/kiosk_mode

If DevicePolicyManager#isLockTaskPermitted(String) returns true for this component, the current task will be launched directly into LockTask mode.

But I'm not familiar with android so I don't know how to add this in flutter.

How can I force the app in koisk mode until I call stopKoiskMode

Any news on this topic? can be done?

Hello,

I am currently developing a kiosk application using Flutter, and I found the 'kiosk_mode' package to be very useful in handling various functionalities on Android and iOS. However, I noticed that this package currently does not support the Windows platform.

In my project, I am also targeting Windows devices, and it's crucial for me to prevent the appearance of the Windows taskbar or triggering of Windows functionalities during certain operations (like scrolling).

The lack of Windows support in the 'kiosk_mode' package creates a significant gap in achieving the desired functionality in my application. Therefore, I am kindly requesting the addition of Windows support for this package.

Has this been considered before, or is there any plan to add Windows support in the near future? If not, I would greatly appreciate it if this feature could be considered for a future update.

Thank you for your time and consideration.

On installing kiosk_mode, APK size increased from 15 MB to 25 MB !! , is it normal?

Hello, my app will live on an Android tablet for the public, so logically I need to restrict what will be accessed. I need my app to always stay open, I can't exit it and when the device starts, it starts automatically (optional).

I'm using kiosk_mode, but the app is just pinned, if the person clicks on the screen the Android buttons are shown, in which they can hold and unpin the app, as well as pull the statusbar down and turn off the Wi-Fi, access the settings, for example.

Is there any way to do this blocking? In the application I hid a hidden button in which after entering a password, there are some settings, such as battery percentage, wifi settings, button to exit kiosk mode, which when clicked calls the stopKioskMode() function, to be able to exit the application in case of update, configuration...

But the problem is that the normal user can exit the application and use the tablet normally

Any idea? Thanks!

Would be nice to have the possibility to disable the toast with the instruction on how to stop the kiosk mode.
