# How to install apps silently in Android Kiosk

Kiosk-enabled devices are business-specific devices that run only the applications approved by the organization. Silent app installation in kiosk mode makes it feasible to distribute in-house apps to the devices without any user intervention. As a result, enabling kiosk mode becomes a lot easier as the enterprise apps automatically get installed on the devices as they are added to the kiosk mode.

 Notes:- Silent App installation of in-house apps (Enterprise apps) is supported on [Samsung Knox](https://www2.samsungknox.com/knoxportal/files/GalaxyDevicesSupportingKNOX.pdf), [LG GATE](http://www.lg.com/us/business/enterprise-mobility/products) and [Kyocera business phones](https://www.kyoceramobile.com/business/phones/), Android devices with Hexnode MDM app as a [system app](https://www.hexnode.com/mobile-device-management/help/what-are-system-apps/), Android devices with [Hexnode MDM System Agent app](https://www.hexnode.com/mobile-device-management/help/system-agent-app/), and on devices enrolled in the Android Enterprise program as Device Owner.
- For LG GATE devices, Hexnode LG Service app is required for silent app installation.

 

Silent App Installation in Android Kiosk
----------------------------------------

First you need to enable [kiosk mode](https://www.hexnode.com/mobile-device-management/help/android-kiosk-mode/) for the Android devices. You could either lock down the device into [single app mode](https://www.hexnode.com/mobile-device-management/help/lock-android-devices-single-app-kiosk-mode/) or [multi app mode](https://www.hexnode.com/mobile-device-management/help/enable-multi-app-kiosk-mode-android-devices/).

 Note: Before enabling the kiosk mode, make sure to add the required apps to the app inventory.

 

 
1. Login to your Hexnode MDM portal.
2. Go to **Policies**.
3. Select an existing policy or create a new one by clicking **New Policy**.
4. From **Kiosk Lockdown > Android Kiosk Lockdown** > select **Single App/Multi App** in accordance with the requirement.
5. Click on **Configure** and add the required apps to the list.
6. Associate the policy with the devices.

Associate Policies with Devices / Groups.
-----------------------------------------

If the policy has not yet been saved.

1. Navigate to **Policy Targets**.
2. Click on **+Add Devices**.
3. Select the devices and click **OK**.
4. Click on **Save** to apply the policies to devices.

Apart from devices, you can also associate the policies with device groups, user and user groups from **Policy Targets**.

If the policy has been saved, you can associate it by another method.

1. From **Policies**, check the policies to be associated.
2. Click on **Manage → Associate Targets** and select the device.
3. Click on **Associate** to apply policy to the devices.

Once the policies are associated, the device will enter into kiosk mode and the apps gets silently installed to the device.

 Notes:- Here the apps are silently installed while adding to the kiosk mode itself. **Install Application** action need not be executed.
- Make sure that you add the apps (in kiosk policy) that are not installed on the device.

 

 Exception: For all devices running MIUI versions that have MIUI optimization turned on, Write System Permissions cannot be enabled. This leads to several issues including kiosk exiting unexpectedly, apps not getting installed silently, and so on. MIUI optimization must be disabled to fix such issues. To disable MIUI optimization:

- Go to Settings > Build Number.
- Tap on the build number 6 to 8 times to enable Developer options.
- Select Developer Options from Settings > Additional Settings.
- Disable MIUI optimization from the list of available options.
