Following the docs https://developers.google.com/android/management/policies/dedicated-devices to setup a KIOSK policy, but result in this error.

Hi @vnwong!

Could you please confirm the app you're testing with is compatible/capable for for this use case? Based on my own reading a few weeks back, the presence of actions and categories in the app manifest matters.

Besides this, are you testing as a fully managed device? If not it work work.

Finally do you have more than one config, or the restriction enabling a kiosk launcher turned on in your policy? This may cause issues.

Thank you for the reply. 

This is my android manifest.xml , please let me know is that any wrong configuration there or direct me to any related reading meterial.

<manifest xmlns:android="http://schemas.android.com/apk/res/android">

By the way, how to we consider a device is a fully managed device? has it to be purchased from specific party? or any device can be a fully managed device as long as running Android OS.

Thank you ~
