Android DeviceOwner Sample

This sample demonstrates how to use some device owner features. As a device owner, you can configure global settings such as automatic time and timezone. You can mandate a specific launcher by preferred intent handler.


In order to set global settings, use [DevicePolicyManager#setGlobalSetting][1] and specify one of the [Settings.Global][2] keys available. Note that you need to specify its value as a String. As most of the keys accept boolean values, you will mostly use "1" for true and "0" for false.

You can mandate a specific launcher by adding a persistent preferred activity for an IntentFilter with Intent.CATEGORY_HOME category. Call [DevicePolicyManager#addPersistentPreferredActivity][3] to register the activity. You can clear the registration with [clearPackagePersistentPreferredActivities][4].

As a device owner, you can also use the features available for managed profile owner. See [BasicManagedProfile][5].
