By default, the system checks for 5 | new OTA updates every few hours and applies them automatically. This example shows 6 | you how to configure the update policy to allow an app to take more control over 7 | the update process and monitor progress. 8 | 9 | > **Note:** The Android Things Console will be turned down for non-commercial 10 | > use on January 5, 2022. For more details, see the 11 | > [FAQ page](https://developer.android.com/things/faq). 12 | 13 | ## Pre-requisites 14 | 15 | - Android Things compatible board 16 | - Android Studio 2.2+ 17 | 18 | ## Getting Started 19 | 20 | Import the project using Android Studio and deploy it to your device: 21 | 22 | 1. Stage a new OTA update for your device using the 23 | [Android Things Console](https://developer.android.com/things/console/index.html). 24 | 1. Press the **Check Now** button on the device to force a manual update check. 25 | 1. The update status is displayed in the UI as the device downloads and verifies 26 | the new update. 27 | 1. Press the **Reboot Now** button to reboot the device and complete the update 28 | process. 29 | 30 | ## Enable auto-launch behavior 31 | 32 | This sample app is currently configured to launch only when deployed from your 33 | development machine. To enable the main activity to launch automatically on boot, 34 | add the following `intent-filter` to the app's manifest file: 35 | 36 | ```xml 37 | 38 | 39 | 40 | 41 | 42 | 43 | 44 | 45 | 46 | ``` 47 | 48 | ## License 49 | 50 | Copyright 2017 The Android Open Source Project, Inc. 51 | 52 | Licensed to the Apache Software Foundation (ASF) under one or more contributor 53 | license agreements.
