Hydra (Android) Android CI

Get it on Google Play

The Android version of the Hydra app, available for Jelly Bean and up. Available on Google Play or as a download here (apk file).



If you don't have Android Studio or Intellij already, download and install it.

  • Clone the repo, i.e. git clone
  • Choose 'Import Project (gradle etc.)'
  • Choose the folder you just cloned
  • Have fun :)

Alternatively, you can checkout the repo directly from within Android Studio or Intellij.


If you want to use the Google Maps integration, you will need the API keys. You can contact us for more information and to obtain the keys. This is not required to compile and build the app.

After you've obtained the keys, you will need to copy the file app/ to app/ and insert the correct keys.

Build variants

Hydra comes in two build variants: store and open. The store variant is the main variant, and used for the Play Store and is the recommended version for most people. The open variant only uses open-source software (e.g. OpenStreetMaps instead of Google Maps). Since the open variant contains no crash reporting functionality, crashes from that version not accompanied by a stack trace will not be considered.
