Crash when transfering ownership to a component

[nktnet1]

Hello - I'm getting the following error:

android.os.RemoteException: Remote stack trace:
	at  (Preconditions.java:64)
	at com.android.server.devicepolicy.DevicePolicyManagerService.transferOwnership(DevicePolicyManagerService.java:19597)
	at android.app.admin.IDevicePolicyManager$Stub.onTransact$transferOwnership$(IDevicePolicyManager.java:15568)
	at android.app.admin.IDevicePolicyManager$Stub.onTransact(IDevicePolicyManager.java:5581)
	at android.os.Binder.execTransactInternal(Binder.java:1500)

When trying to transfer ownership to my application.

However, I can set it as "owner" just fine using Android Debug Bridge (ADB).

Why would this be the case?

Do you have any suggestions for how it can be fixed?

My AndroidManifest.yml has the following:

        <receiver
            android:exported="false"
            android:name=".WebviewKioskAdminReceiver"
            android:permission="android.permission.BIND_DEVICE_ADMIN">
            <meta-data
                android:name="android.app.device_admin"
                android:resource="@xml/device_admin" />
            <intent-filter>
                <action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
            </intent-filter>
        </receiver>

and device_admin.yml:

<device-admin>
    <uses-policies>
    </uses-policies>
</device-admin>

Things I've tried (all unsuccessful):

• toggling android:exported
• toggling android:manifest
• adding/removing policies in device_admin.yml
• using signed APKs instead of debug/test
• tweaking intent-filter

Have simply settled for using adb for now.

Thanks.

Needed to add support-transfer-ownership to the receiver's meta-data xml file, e.g. nktnet1/webview-kiosk@567a923:

<device-admin>

    <!-- ... -->

    <support-transfer-ownership />

    <!-- ... -->

</device-admin>

Note that your IDE (e.g. Android Studio) may warn with the following error:

Element support-transfer-ownership is not allowed here
