This Android Things sample demonstrates how to connect to a GPS unit that emits data via UART in the NMEA format, and integrates it into the Android location framework.
- Android Things compatible board
- Android Studio 2.2+
- 1 GPS NMEA-compatible module with UART interface, like the Ultimate GPS hat
- jumper wires
- 1 breadboard
If using the Raspberry Pi Ultimate GPS Hat, just plug it onto your Raspberry Pi 3.
NOTE: Raspberry Pi 3 shares the UART pins between multiple ports, including the serial debugging console. Refer to the mode matrix for more details.
On Android Studio, click on the "Run" button.
If you prefer to run on the command line, from this repository's root directory, type
./gradlew gps:installDebug
adb shell am start com.example.androidthings.driversamples/.GpsActivityIf you have everything set up correctly, a log will be generated on logcat whenever there is a location update.
Notice that the GPS driver integrates with the Android location framework using a GpsDriver user driver and fuses with other location sources, so the part of the app that handles the location updates works exactly the same no matter which, or how many location sources are available.
