+As of v3.3.1 OpenTracks enables to use custom dashboards.
+The reference implementation is [OSMDashboard](https://github.com/OpenTracksApp/OSMDashboard), which presents an OpenStreetMap map (showing the current track, incl. updates).

+# OpenTracks Data API
+
+## Reason
+OpenTracks by itself only provides basic features for data visualization and also lacks functionality for analytics.
+By itself OpenTracks provides a basic dashboard that can show summary of a track (while recording as well as afterwards).
+Although this might be (mostly) sufficient, it has some limitations.
+This include limited configurability (e.g., ordering of shown elements) and the lack of Internet access.
+In fact, the later is considered a feature but severely limits the implementation presenting a map (at least in an easy way). 
+
+_NOTE:_ for showing a track on a map a workaround was implemented in OpenTracks.
+Data could be exported as KMZ and presented in 3rd-party application (e.g., [OsmAnd](https://play.google.com/store/apps/details?id=net.osmand) or [MAPS.ME](https://play.google.com/store/apps/details?id=com.mapswithme.maps.pro)). 
+
+For the time being, the OpenTracks Data API can be used to implement mainly custom dashboards.
+
+## Implementation
+OpenTracks by default does not expose any data to 3rd-party applications.
+On the request of the user (i.e., pressing a button), an Intent is created that exposes the `Track` data (it's summary) as well as the `TrackPoint`s of one or more selected tracks.
+For each, one URI is provided.
+These URIs notify observers if on content changes (e.g., a new `TrackPoint` was added).
+
+Limitations:
+* only tracks selected by the user are exposed,
+* `Waypoints` are not exposed,
+* access is only granted temporarily and automatically revoked (see `FLAG_GRANT_READ_URI_PERMISSION`),
+* no write access is possible, and
+* neither track recordings can be started, paused, or stopped.
+
+All required information can be found in `IntentDashboardUtils.java`. 
+
+A _reference implementation_ is the [OSMDashboard](https://github.com/OpenTracksApp/OSMDashboard).

+## F-Droid
+Application id: de.dennisguse.opentracks
+
+It if it properly tagged F-Droid takes care of building the app and publishing.
+Usually, it takes two days before the update is published (build, signed, and published). 
+
+The recent build activity can be found [here](https://f-droid.org/wiki/index.php?title=Special:RecentChanges&days=7&from=&hidebots=0&hideanons=1&hideliu=1&limit=500)
+
+## Google Play Store
+Application id: de.dennisguse.opentracks.playstore
+
+Requirement: `gem install fastlane`
+
+1. Build signed apk
+   (requires keystore)
+2. Upload signed apk to [Google Play Console](https://play.google.com/apps/publish)
+3. Update store meta data (e.g., description and screenshots)
+   `fastlane supply --version_code VERSION_CODE --skip_upload_apk`
+   (use the version code from the manifest)
+   (requires API key)

- * This is a helper class that implements the management of tabs and all details
- * of connecting a ViewPager with associated TabHost. It relies on a trick.
- * Normally a tab host has a simple API for supplying a View or Intent that each
- * tab will show. This is not sufficient for switching between pages. So instead
- * we make the content part of the tab host 0dp high (it is not shown) and the
- * TabsAdapter supplies its own dummy view to show as the tab content. It
- * listens to changes in tabs, and takes care of switch to the correct paged in
- * the ViewPager whenever the selected tab changes.

- * Copied from the FragmentTabsPager sample in the support library.
