[Android TV General] Veroland:
I have a Kiosk application and I want it to be able to update itself. To this end I am trying to run the application as a Device Owner on a Mi TV Stick. The model is MiTV-AESP0 and the kernel is 4.9.113

Please the dpm command works when I run it against an emulator with Android TV 9 on.

I have set up a Receiver for the admin service

public class DeviceAdminBroadcastReceiver extends DeviceAdminReceiver {
private static final String TAG = DeviceAdminBroadcastReceiver.class.getSimpleName();
public static ComponentName getComponentName(Context context) {
return new ComponentName(context.getApplicationContext(), DeviceAdminBroadcastReceiver.class);
}

@Override
public void onEnabled(Context context, Intent intent) {
super.onEnabled(context, intent);
Log.d(TAG, "Device Owner Turned ON");
}
@Override
public void onDisabled(Context context, Intent intent) {
super.onDisabled(context, intent);
Log.d(TAG, "Device Owner Turned OFF");
}
@Override
public void onLockTaskModeEntering(Context context, Intent intent, String pkg) {
// invoked when any app enters "kiosk" mode
}
@Override
public void onLockTaskModeExiting(Context context, Intent intent) {
// invoked when exiting "kiosk" mode
}
}

In my manifest file I have declared the receiver

<receiver
android:name=".receivers.DeviceAdminBroadcastReceiver"
android:exported="true"
android:label="@string/app_name"
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" />
<action android:name="android.app.action.DEVICE_ADMIN_DISABLED" />
</intent-filter>
</receiver>

in my res/xml folder I have a device_admin.xml file

<device-admin xmlns:android="http://schemas.android.com/apk/res/android">
</device-admin>

If I try to run it against the TV Stick I get the following:

adb shell dpm set-device-owner com.tfsdisplays.packagemanager.local/com.tfsdisplays.packagemanager.receivers.DeviceAdminBroadcastReceiver
java.lang.RuntimeException: Can't set package ComponentInfo{com.tfsdisplays.packagemanager.local/com.tfsdisplays.packagemanager.receivers.DeviceAdminBroadcastReceiver} as device owner.

The same command work against the emulator is it is connected to ADB. I have tried USB debugging with a cable and WIFI. ADB versions 40 and 41.

I have done a factory reset on TV stick as well, nothing seems to make a difference. There is no accounts on the Stick and a device_policy dump shows the following:

adb shell dumpsys device_policy
Current Device Policy Manager state:

Enabled Device Admins (User 0, provisioningState: 0):

mPasswordOwner=-1

Please, I am at my wits end here, does anyone have any idea? Thank you in advance
