Answer 1

The process is described in depth in the Device Administration guide in the Android developer documentation.

At a high level, the steps are:

• Create a DeviceAdminReceiver and register it in your manifest
• Launch an Intent with the ACTION_ADD_DEVICE_ADMIN action, and pass your receiver as the DevicePolicyManager.EXTRA_DEVICE_ADMIN, extra.

Once the user has accepted your device as a device administrator, you can perform a limited set of device administration actions in your application.

You would need 3 thing to do :

1. add <receiver> to AndroidManifest
2. make new xml file for <device-admin>
3. make new .kt file for DeviceAdminReceiver

Example :

in AndroidManifest.xml (inside <activity>, add the code below) :

<receiver
        android:name=".MyDeviceAdminReceiver"
        android:description="@string/app_name"
        android:label="@string/app_name"
        android:permission="android.permission.BIND_DEVICE_ADMIN">
        <meta-data
            android:name="android.app.device_admin"
            android:resource="@xml/device_owner_receiver" />
        <intent-filter>
            <action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
        </intent-filter>
    </receiver>

in device_owner_receiver.xml, add this code :

<?xml version="1.0" encoding="utf-8"?>
<device-admin>
    <uses-policies>
        <limit-password />
        <watch-login />
        <reset-password />
        <force-lock />
        <wipe-data />
        <expire-password />
        <encrypted-storage />
        <disable-camera />
    </uses-policies>
</device-admin>

in MyDeviceAdminReceiver.kt, add the code below :

class MyDeviceAdminReceiver : DeviceAdminReceiver() {
    override fun onEnabled(context: Context, intent: Intent) {
        super.onEnabled(context, intent)
        Toast.makeText(context, "Admin is enabled", Toast.LENGTH_SHORT).show()
    }
}

When you run the app after adding the code at the top, the app will prompt an admin request.
