Capstone project for the Android developer scolarship from Google and Udacity
That’s the app for minimizing users interactions with the waiters in restaurants, cafes etc. The user makes a booking or comes to a cafe straight away, connects to the Android Things module near the table using Nearby Connections, gets a menu, wifi credentials and connects to cafes network (optionally). The user makes an order on its phone and sends it back to the Android Things module using Nearby Connections, where module sends the order to the Firestore database. Then the app shows estimated waiting time and checks in Android Things module if the waiter has brought the order and if so, shows options to open a menu and order some additional stuff, close the order by paying with Google Pay or call the waiter to pay.
So the project actually consists of 2 apps: one for a clients phone (/app) and one for the Android Things module (/things).
The implication is that the cafes information system will use the same Firestore database as the Android Things module. Cafes information (such as name, menus, table) will be faked and can be changed for a real cafe.
1. The project needs 3 additional files to be added.
- gradle.properties in the root folder with a few parameters added:
GoogleSignInClientId = "YOUR_GOOGLE_OAUTH_2.0_CLIENT_ID"
NearbyServiceId = "YOUR_CUSTOM_NEARBY_SERVICE_ID"
WifiSSID = "YOUR_WIFI_SSID"
WifiPassword = "YOUR_WIFI_PASSWORD"Get your Google Client Id by following this instruction.
- google-services.json in the /app directory
- google-services.json in the /things directory
Google services files can be generated automatically by the Android Studio using Firebase Assistant. Connect Firebase Authenticate (Email/password and Google sign-in options) and Firebase Firestore in both project modules.
2. Clients Android app (/app) can be installed on your phone (emulator may not work with Nearby Connections) from Android Studio as usual.
3. In order to run the Android Things module (/things) all you need is supported Android Things board (such as Raspberry Pi 3) with Android Things installed, connected to the internet and connected to the ADB. Then you can install Android Things module from Android Studio as usual.
In my opinion, the most simple way to install Android Things and connect it to the ADB is the following:
- Download the development Android Things image.
- Flash it on microSD card using something like Win32 Disk Imager.
- Insert card onto your RPi 3, connect the board to the Ethernet (or via WiFi later), external monitor, power and turn it on.
- When the board is started you should see its local IP address on the monitor (otherwise, you can plug in a USB keyboard to your RPi and connect to the Internet using WiFi), use it to connect to adb using
adb connect IP.
No additional peripheral hardware for Android Things is required.
