This layout is referred to as basic store layout. The EMM's console should allow IT admins to manage the apps visible in an end user's basic store layout. IT admins can customize the store layout seen in the managed Google Play Store app.
IT admins can upload new versions of apps that are already published privately to the enterprise using:. IT admins can set up and publish self-hosted private apps. The server can be on-premise or cloud-based. Not correcting behavior that exceeds these guidelines may result in suspension of API use, at Google's discretion. The EMM should distribute traffic from different enterprises throughout the day, rather than consolidating enterprise traffic at specific or similar times.
Behavior that fits this traffic pattern, such as scheduled batch operations for each device enrolled, may result in suspending API use, at Google's discretion.
The EMM should not make consistent, incomplete, or deliberately incorrect requests that make no attempt to retrieve or manage actual enterprise data. Behavior that fits this traffic pattern may result in suspended API use, at Google's discretion. The EMM's console must be able to retrieve and display the up to four levels of nested managed configuration settings of any Play app, using:.
The EMM's console must be able to retrieve and display any feedback returned by an app's feedback channel , when set up by an IT admin. IT admins can silently set a default response to runtime permission requests made by work apps.
IT admins must be able to choose from the following options when setting a default runtime permission policy for their organization:. The EMM should enforce these settings via policy. After setting a default runtime permission policy go to 4. IT admins must be able to set the grant state default, grant, or deny of any permission requested by any work app built on API 23 or above.
IT admins can silently provision enterprise Wi-Fi configurations on managed devices, including:. IT admins can provision enterprise Wi-Fi configurations on devices that include the following advanced security features:. IT admins can lock down Wi-Fi configurations on managed devices, to prevent users from creating configurations or modifying corporate configurations. IT admins can lock down corporate Wi-Fi configurations via policy in either of the following configurations: Users cannot modify any Wi-Fi configurations provisioned by the EMM go to wifiConfigsLockdownEnabled , but may add and modify their own user-configurable networks for instance personal networks.
IT admins can ensure that only authorized corporate accounts can interact with corporate data, for services such as SaaS storage and productivity apps, or email. Without this feature, users can add personal accounts to those corporate apps that also support consumer accounts, enabling them to share corporate data with those personal accounts. IT admins can prevent users from adding or modifying accounts see modifyAccountsDisabled.
Allows IT admins to deploy identity certificates and certificate authorities to devices to allow use of corporate resources. IT admins can install user identity certs generated by their PKI on a per-user basis. The EMM's console must integrate with at least one PKI and distribute certificates generated from that infrastructure.
IT admins can install certificate authorities see caCerts in the managed keystore. Allows IT admins to silently select the certificates that specific managed apps should use. This feature also grants IT admins the ability to remove CAs and identity certs from active devices, and prevent users from modifying credentials stored in the managed keystore.
For any app distributed to devices, IT admins can specify a certificate the app will be silently granted access during runtime. This subfeature is not currently supported. IT admins can silently remove certificates from the managed keystore. IT admins can silently uninstall a CA certificate. IT admins can prevent users from configuring credentials go to credentialsConfigDisabled in the managed keystore. IT admins can distribute a third-party certificate management app to devices and grant that app privileged access to install certificates into the managed keystore.
IT admins can specify a certificate management package go to delegatedCertInstallerPackage to be set as the delegated certificate management app. IT admins can use managed configurations to specify the VPN settings for an app. IT admins can manage what input methods IMEs can be set up for devices. IT admins can manage what input methods IMEs users can set up on a device.
Advanced IME management extends the basic feature by allowing IT admins to manage the use of system IMEs as well, which device manufacturer or carrier of the device typically provide. IT admins can manage what accessibility services users can allow on devices. Accessibility services are powerful tools for users with disabilities or that are temporarily unable to fully interact with a device. However, they may interact with corporate data in ways that are non-compliant with corporate policy.
This feature allows IT admins to turn off any non-system accessibility service. IT admins can set up an accessibility service allowlist go to permittedAccessibilityServices of arbitrary length including an empty list, which blocks non-system accessibility services , which may contain any arbitrary accessibility service package. IT admins can prevent users from sharing location data with apps in the work profile. Otherwise, the location setting in the work profile is configurable in Settings.
IT admins can disable location services go to shareLocationDisabled within the work profile. IT admins can enforce a given Location Sharing setting on a managed device. This feature can ensure that corporate apps always have high accuracy location data. This feature can also ensure that extra battery is not consumed by restricting location settings to battery saving mode. IT admins can set the device location services to each of the following modes:. If factory reset protection introduces operational complexities when devices are returned to IT, IT admins can turn off factory reset protection entirely.
IT admins can prevent users from factory resetting go to factoryResetDisabled their device from Settings. IT admins can specify corporate unlock account s authorized to provision devices go to frpAdminEmails after a factory reset.
This account can be tied to an individual, or used by the entire enterprise to unlock devices. IT admins can disable factory reset protection go to0 factoryResetDisabled for specified devices. IT admins can start a remote device wipe that optionally wipes reset protection data, thus removing factory reset protection on the reset device. IT admins can prevent the user from uninstalling or otherwise modifying managed apps through Settings.
For instance, preventing force closing the app or clearing an app's data cache. IT admins can block uninstall of any arbitrary managed apps, or all managed apps go to uninstallAppsDisabled. IT admins can prevent users from modifying application data go to appsControlDisabled from Settings. IT admins can block users from taking screenshots when using managed apps.
This setting includes blocking screen sharing apps and similar apps such as Google Assistant that leverage the system screenshot capabilities. IT admins can prevent users from capturing screenshots go to screenCaptureDisabled. IT admins can disable use of device cameras go to cameraDisabled by managed apps. IT admins can remotely reboot a managed device. Provides IT admins with granular management over system network radios and associated use policies via policy. IT admins can turn off cell broadcasts sent by service providers go to cellBroadcastsConfigDisabled.
IT admins can prevent users from modifying mobile network settings in Settings go to mobileNetworksConfigDisabled. For the sake of clarity, this document simplifies and excludes many things. We think we can get away with this because we also recommend using a library such as Google's Shaka Player. I will note throughout where I'm deliberately simplifying. As with many things in web development these days, you start with feature detection. Finally create an instance of MediaSource.
It gets turned into a URL and passed to the media element's source attribute. That a MediaSource object can be passed to a src attribute might seem a bit odd.
They're usually strings, but they can also be blobs. If you inspect a page with embedded media and examine its media element, you'll see what I mean. This causes a slight delay before you can do anything with the MediaSource instance. Fortunately, there are ways to test for this. The simplest way is with a MediaSource property called readyState.
The readyState property describes the relation between a MediaSource instance and a media element. It can have one of the following values:. Querying these options directly can negatively affect performance.
Fortunately, MediaSource also fires events when readyState changes, specifically sourceopen , sourceclosed , sourceended. For the example I'm building, I'm going to use the sourceopen event to tell me when to fetch and buffer the video. I know this seems premature, but I can do this any time after the media element's src attribute is connected to a MediaSource instance. Calling this method doesn't destroy any objects. It does allow the platform to handle garbage collection at an appropriate time, which is why I'm calling it immediately.
Now it's time to create the SourceBuffer , which is the object that actually does the work of shuttling data between media sources and media elements. A SourceBuffer has to be specific to the type of media file you're loading. In practice you can do this by calling addSourceBuffer with the appropriate value. Notice that in the example below the mime type string contains a mime type and two codecs. This is a mime string for a video file, but it uses separate codecs for the video and audio portions of the file.
Version 1 of the MSE spec allows user agents to differ on whether to require both a mime type and a codec. Those functions must take a string and return a string. Defaults to:. Pre-processing and tokenizing. TypeError — When fp is not a file-like object that takes bytes. Attempt to guess what went wrong by using known information e.
The easiest way to get a list of available languages is to print them with gtts-cli --all. Languages fetched from Google Translate pre-generated in gtts.
