Managing AOSP-based TV with Hexnode UEM

Android TVs are revolutionizing the enterprise ecosystem having numerous applications in industries of any kind or size. With a wide adoption in the enterprise market, the management of Android TV devices has proved to be a critical requirement for organizations.

When it comes to Android TV, there are two different variants available — Devices running Android TV OS & AOSP (Android Open-Source Project) -based Android TVs. AOSP-based TV brings the Android experience to television screens with its customized launcher, voice interface, app store, and more. It’s Android under the hood with Google’s integrated services and is specifically designed for smart TVs, set-top boxes, and other digital media players.

Deploying and manually attending to large fleets of TV devices can be daunting for IT administrators. This article will guide you in managing the entire lifecycle of AOSP-based TVs using Hexnode UEM.

Note:

  • Hexnode supports the management of all AOSP Android TV devices running Android 4.1 or later versions.

Enrolling an AOSP-based TV

Device enrollment is the initial phase of device management. You need to enroll your AOSP-based TVs in the Hexnode UEM portal before you can start managing them. Prior to enrolling devices, make sure to configure the required enrollment settings in the portal.

To begin the enrollment process, you’ve to install the Hexnode UEM app on the devices via Google Play Store or the APK file. Then, open the app and enter the server name. Next, authenticate with your directory or local credentials if ‘Enforce Authentication’ is enabled under ‘Enrollment Settings’. In case the authentication mode is set to ‘No Authentication’, follow the on-screen instructions to complete the enrollment process.

Moreover, with the support of pre-approved enrollment, administrators can proactively apply restrictions and configurations to the AOSP-based TVs, even before the enrollment is completed from the user-end. As the device is manually enrolled later, all the applied policies will take effect. However, note that pre-approved enrollment is not available for TVs running Android 10 or later versions.

Note:

  • Except for the enrollment methods mentioned above, AOSP-based TV does not support other Android-specific enrollments, including Zero-touch, Knox Mobile Enrollment (KME), or Android Enterprise (AE) enrollments.
  • Non-Android Enterprise Device Owner enrollment via ADB is supported on devices running Android v5.0 or later.

Remote Actions – one-time activity

Newly enrolled devices will be listed under Manage > Devices. The Manage tab offers a plethora of quick device management and monitoring capabilities. You can execute a bunch of one-time actions on an individual device or multiple devices. Some of the major actions supported on AOSP-based TVs include:

Remotely View TV screens

Pre-requisites:

  • Ensure to check ‘Enable Remote View’ from Admin > General Settings > Remote View & Control Settings.
  • Make sure that the Hexnode Remote View app is installed on the device.
  • Keep the following ports open: Port 80, Port 443, Port 3478, Port 5349.

The Remote View module available on the Device Summary page of a device will facilitate administrators to view the TV screens in real-time. You can also adjust the remote video quality and rotate screens at your convenience. Follow the steps mentioned below to enable the remote view of AOSP-based TVs:

  1. Head on to Manage > Devices.
  2. Click on the TV device from the list of devices. This will take you to the device details page.
  3. Click on Start Session under the Remote View panel to remotely view the device.

Real-time location tracking and Geofencing

Pre-requisites:

AOSP-based TVs do not have a GPS module. So, Hexnode uses the device’s network information to estimate the location of the device. An admin can enable periodic or instantaneous location tracking to fetch the whereabouts of the device. It also stores the complete history of locations traversed by the devices. Hexnode offers multiple ways to view the location of the device from its console:

  • The Location History widget available in the Dashboard displays the location of all location-enabled devices.
  • The Location History tab available in the device details page displays the history of locations traversed, last check-in, and total check-in status of individual devices.
  • The Recent Location under Device Summary showcases the recent location and last reported time of individual devices.
  • The Locations tab under Users/Device Groups/User Groups will also show the location details of the respective Users/Device Groups/User Groups.

The geofencing feature lets you create virtual geographical fences and apply configurations or restrictions for devices that are within or outside of the virtual boundaries. Any devices that enter a restricted region or move out of the specified region will be marked as non-compliant in the portal.

Restrictions

Hexnode offers an exhaustive list of restrictions to control and manage AOSP-based TVs. These devices support all restrictions except those specific to Samsung Knox, LG GATE, Kyocera business phones, or devices enrolled in the Android Enterprise program.
To configure the restrictions:

  1. Head on to Policies > Android > Restrictions.
  2. Configure the set of restrictions mentioned below for your Android TV:
    • Safe mode
    • Screen Orientation (may not work as expected on some devices)
    • Screen Timeout
    • Wi-Fi
    • Force Wi-Fi
    • Bluetooth
    • Force Bluetooth
  3. Associate the restrictions with the target devices and save the policy.

Manage the lifecycle of apps

You can add, distribute, or remove store or enterprise apps on AOSP-based TVs without a hassle. Distributing these apps to the devices will prompt the users to initiate the installation process.

Initially, you have to add apps to the app inventory. You can add apps from the Play Store, enterprise apps, web apps, and add apps using their Bundle IDs. You can also create app groups (Apps > App Groups) to add multiple apps to a bundle for distribution.

You can distribute the apps to the target devices in three ways:

  • Push apps via the Mandatory Apps policy to ensure all the essential apps are installed on the device.
  • Execute a one-time action – Install Application.
  • Deploy an App Catalog (Apps > App Catalog) that contains the required set of apps.

Hexnode also allows you to push store and enterprise app updates to your TVs running Android OS. Automatic update of store apps works for apps that are initially distributed via the Mandatory Apps policy. Updating enterprise apps requires either replacing the older app version or updating the new version to the app inventory.

You can also initiate the removal of apps without needing any physical access to the device. However, users will be prompted to uninstall the apps from the device.

Transform AOSP-based TVs to digital kiosks

AOSP-based TVs for digital signages

Digital signage displays are becoming essential in almost all business environments. Businesses now find TVs running Android OS as an excellent choice for digital signages since it has a much lesser lower price-point compared to their Android counterparts. The flexibility and enhanced performance make them an excellent solution for digital signages with shallow interaction. So, companies are in need of a cost-effective solution that can manage and control these displays remotely.
With Hexnode, you can seamlessly transform your AOSP-based TVs running Android OS into digital signages. Administrators can manage and control multiple TV screens from any place, any time. It provides a quick, cost-effective solution for displaying digital signages with enhanced streaming controls. To set up digital signage,

  1. Navigate to Policies > Kiosk Lockdown > Android Kiosk Lockdown > Digital Signage Display.
  2. Add the required files, images, or videos to the policy. You can also play the media files in loops and add custom background music.
  3. After configuring the required parameters, associate the digital signage display policy with devices from Policy Targets.
  4. Click Save.

Lockdown TV to single or multiple apps

The single-app mode allows businesses to lock down their AOSP-based TV to a single application. Whereas the multi-app mode transforms the device to run one or more IT-approved apps, restricting access to all other apps and device functionalities. To configure a single-app/multi-app kiosk policy,

Hexnode Browser Lite is a single tabbed browser that offers advanced settings to customize the overall website kiosk experience. It can be configured to run in the single-app kiosk or multi-app kiosk mode. Hexnode Kiosk Browser enables safe browsing by restricting access to only the websites approved by the organization.

You can also opt for any other browser other than the Hexnode browsers. In that case, the browser app needs to be installed on the device. The browser app must be initially added to Single App, Multi App, or Background Apps to list it in the ‘Select Browser’ field when choosing the ‘Another Browser’ option under Website Kiosk Settings. You can add the browser as a background app if you don’t want it to be shown in the foreground.

Hexnode also offers a plethora of configurations to customize and manage the website kiosk using the Hexnode Browser Lite or Hexnode Kiosk Browser. The configurations include toolbar, appearance, content, location, forms, and many other settings.

Run apps in the kiosk background

Certain situations may demand running some non-kiosk applications for the smooth operations of the apps added in the kiosk mode. The Background Apps feature lets you run such apps in the kiosk background without displaying its app icon. Follow the below instructions to set apps as background apps:

  2. Add the apps you need to run and hide in the kiosk background.
  3. Next, apply the policy to the target devices from Policy Targets and click Save.
Note:

  • You can either set background apps within the same single-app/multi-app kiosk policy or create a new one. In the latter case, make sure to associate the single-app or multi-app kiosk policy with the device before applying the background app policy.

Customize Kiosk Launcher

Launcher settings allows organizations to customize the kiosk launcher on their Android devices and configure auto-launch settings for a particular kiosk app added to a single/multi-app kiosk mode.

Configure the auto-launch settings to set a kiosk app (or a file shortcut) as the default app in kiosk mode. Enterprises can ensure that this default kiosk app launches automatically and runs in the foreground as per the ‘App auto-launch delay’ period specified in the launcher settings. This setting will be beneficial to manually exit kiosk mode on single app mode-enabled devices as exiting kiosk mode on such devices is rather tedious. In this case, users can make use of the specified auto-launch delay period to return from the app to the kiosk home screen. Then, tap on the screen for the specified number of times (Android Kiosk Lockdown > Kiosk Exit settings > Number of taps to display popup to enter the exit passcode) in quick succession to initiate kiosk exit. Note that this feature is also available for multi-app kiosk mode.

The customization settings offer a plethora of options to customize the kiosk launcher as per the needs of the enterprise. Here, administrators can set the icon size, logo, title, and so on.

To configure the launcher settings:

  1. Navigate to Policies > Kiosk Lockdown > Android Kiosk Lockdown > Launcher.
  2. Configure the auto-launch and customization settings, and associate them with the target devices from Policy Targets.
  3. Click Save.

Configure Peripheral settings

Peripheral settings can be configured to attain granular controls over networks, display, location, apps, and more. These configurations will allow the users to have seamless access to some of the essential settings on the devices while the device is in kiosk mode. Here’s how to configure peripheral settings:

  2. Configure the required settings and apply the policy to the target devices from Policy Targets.
  3. Click Save.

Disable kiosk mode

Hexnode offers a set of options to exit kiosk mode on Android devices either from the UEM console or from the device itself. The methods to disable kiosk mode from the UEM console work only if the devices are connected to the internet. In case the devices are offline, users can resort to manual disenrollment methods. Hexnode also enables users to remove the kiosk mode manually, even if the devices are offline.

Automate periodic synchronization

Periodically sync your AOSP-based TVs with the Hexnode portal to force the Hexnode UEM app to check in with the devices. You can set the periodic sync behavior to either Background service or Foreground service. Running the periodic sync as a background service will not sync the devices with the Hexnode portal if the battery saver or data saver modes are enabled on the devices. Also, if the devices are idle for a longer period of time, they may not respond to the Hexnode server. Consequently, any actions or policies pushed via the portal will not reach the devices. An admin can eliminate these difficulties by switching the sync behavior to the foreground service.

Configure Wi-Fi connections

Remotely configure Wi-Fi on AOSP-based TVs to automatically connect to networks when they come in the vicinity of the networks.

To set up a Wi-Fi connection on your TV,

  1. Navigate to Policies > Android > Networks > Wi-Fi on the Hexnode portal.
