Install Updates For A Device-owner App

Does anyone know what is the behavior in production of a device-owner App, distributed thru Google Play, when updates occur? As we know, installing a device-owner App involves some

Solution 1:

Once your Device Owner app is set, a new file is created under /data/system/device_owner.xml that references the Device/Profile owner apps.

The Android system is then reading this file to check which application is considered as Device Owner or Profile Owner App.

This file contains refers to the applications by using their package name. Updating these apps won't infer on this file since the package name stays the same. When you're updating your app, just make sure you're always using the same certificate as the one you previously used when first setting you device owner for the first time (which is a standard rule of security for every application update in Android anyway). Permissions can also be updated the same way, without the need to reprovision it through NFC, nor dpm tool.
