This project showcases the current features of the Android UWB Jetpack library.
Includes code examples for:
- Device compatibility - How to check if an Android device supports UWB.
- Device Discovery - Ultra-wideband currently does not support a native way to discover devices, so an out of band (OOB) mechanism must be provided. This project uses the NearBy Connections API, but other radio protocols like Bluetooth, BLE, or Wi-Fi could also be used.
- Simple Ranging - The Ranging screen displays the controllee's distance from the the controller.
- Device Control - The Control screen simulates a use case where a door lock could be opened when a UWB-capable device is near by.
- Share Media - The Share file screen demonstrates how to transfer a media file using the selected OOB mechanism when devices are in close proximity.
- Settings - In this screen you can select which Android device will play each role (Controller or Controlee).
- Two UWB-capable Android phones with Android 12 or higher
- Latest version of the Core Ultra Wideband (UWB) library
- An end to end example of Ultra-wideband technology. The main goal is to demonstrate basic ranging capabilities between two Android devices and how a selected OOB mechanism could be used to facilitate real use cases. For the latest information on the library status check this article
- A reference for a real production app with proper security, network access, app permissions, user authentication, etc. Check out the Now in Android app instead.
- A UI/Material Design sample. The interface of the app is deliberately kept simple to focus on the UWB use cases. Check out the Compose Samples instead.
- A complete Jetpack sample covering all libraries. Check out Android Sunflower or the advanced GitHub Browser Sample instead.
- Intermediate developers looking for a simple way to understand how the UWB Jetpack library can be used.
- Advanced developers looking for a quick reference.
To open this app in Android Studio, begin by checking out the entire connectivity-samples project:
- Clone the repository, this step checks out the master branch.:
git clone [email protected]:android/connectivity-samples.git
- Open the
UwbRangingfolder in the IDE.
