OwnTracks for Android

This is the OwnTracks Android app. See our booklet for details on how to get started with OwnTracks, as well some details about behaviour specific to the Android app.

Build flavours

There are two build flavours for OwnTracks:

• gms: This is the build published to the Google Play Store. It links to and requires the Google Play Services libraries for location (using the Google location APIs), as well as the Google Maps SDK for drawing the main map.
• oss: This is an "un-Googled" build, which does not require or depend on Google Play Services. It uses the built-in android location capabilities and defaults to OpenStreetMap for the main map. Available via F-Droid. N.B. this is currently unavailable until we remove a specific closed-source dependency. See #1288

Both flavours are published as an APK to Github releases.
