Collecting and analyzing vehicle sensor data
enviroCar Mobile is an Android application for smartphones that can be used to collect Extended Floating Car Data (XFCD). The app communicates with an OBD2 Bluetooth adapter while the user drives. This enables read access to data from the vehicle’s engine control. The data is recorded along with the smartphone’s GPS position data.The driver can view statistics about his drives and publish his data as open data. The latter happens by uploading tracks to the enviroCar server, where the data is available under the ODbL license for further analysis and use. The data can also be viewed and analyzed via the enviroCar website. enviroCar Mobile is one of the enviroCar Citizen Science Platform’s components (www.envirocar.org).
Key Technologies
Benefits
Use the Google Play Store to install the app on your device.
We are planning to include the project into F-Droid in the near future.
This software uses the gradle build system and is optimized to work within Android Studio 1.3+. The setup of the source code should be straightforward. Just follow the Android Studio guidelines for existing projects.
The enviroCar App project uses the Mapbox Maven repository. Mapbox is a mapping and location cloud platform for developers.
To build the project you need the mapbox account, you can create an account for free from here.
Once you have created an account, you will need to configure credentials
Downloads:Read scope.gradle.properties file. You should not expose the token in public, that's why add gradle.properties in .gitignore . It's also possible to store the sercret token in your local user's gradle.properties file, usually stored at _«USERHOME»/.gradle/gradle.properties. gradle.properties file and add this line MAPBOX_DOWNLOADS_TOKEN = <your-secret-token>. The secret token has to be pasted without any quote marks.
MAPBOX_DOWNLOADS_TOKEN=sk.dutaksgjdvlsayVDSADUTLASDs@!ahsvdaslud*JVAS@%DLUTSVgdJLA&&>Hdval.sujdvadvasuydgalisy(this is just a random string, not a real token)If you are still facing any problem, checkout the Mapbox guide or feel free to create an issue

The repository also contains a simple OBD simulator (dumb, nothing fancy) that can be used on another Android device and mock the actual car adapter.
This app is in operational use in the CITRAM - Citizen Science for Traffic Management project. Check out the enviroCar website for more information about the enviroCar project.
