A device owner is an application that runs as a device administrator on your Android device. But it has more control over the device than a device administrator as it get's access to a set of unique APIs. This is new concept was introduced for Android 5.0 and above.
Wondering when to use the device ownership application? You can define the WSO2 Android agent as the Device Ownership application for devices that are enrolled with WSO2 IoT Server and don't have the system service application installed. This way you can impose restrictions on the device that you weren't able to impose when the device in the device administrator state. For more information on the restrictions that can be imposed by the device ownership application, see Available Android Mobile Device Management Policies.
Please note that the restriction functions of the device ownership application do not work for Samsung devices at the moment.
Let's get started!
Device ownership application functionality
Let's take a look at how an application having the device ownership settings enabled, function.
- Once the device ownership is assigned to an application, it gets access to a set of Android APIs, such as adding a user restriction policy on Android devices. These APIs are only accessible by the device ownership application.
- At a given time a device can only have one application with the device ownership settings. It prevents another device ownership application from overriding the policies that have already been enforced on the device.
- If you wish to remove the device ownership from the application, you need to factory reset the device. For example, in a situation where the device needs to be given to a different user, you need to factory reset the device to remove the application.
Configuring the WSO2 Android agent
Before you begin
Make sure to have the Android agent installed on your device. For more information, see enrolling an Android device.
Let's take a look at how WSO2 IoT Server configures the device ownership settings on the agent.
Assign the device ownership to the WSO2 Android agent using one of the following methods.
The device ownership settings only work for SDK API levels 21 and above.

Integrating the service application with WSO2 IoT Server
To successfully integrate the service application with WSO2 IoT Server you need to have the WSO2 Android agent installed as well. Take a look at the diagram given below to clearly understand the role of the Android agent in this scenario.
