Release v3.9.2

* correct thread handling in ButtonDelay

Discovered in #390 for devices with API Level 25. Not fixing the whole issue, but a first step.

* fix #390 crash when stopping for older devices

The VectorDrawable ic_button_stop.xml referenced from withing the AnimatedVectorDrawable ic_button_stop_anim.xml was a problem for older devices. Now the VectorDrawable is expanded (duplicated) inside the AnimatedVectorDrawable. Now it is working. Even with the animation.

-_Please note:_
-_Tracks_ does not contain a _map_ (as this would required Internet access).
-To show your tracks on a map, a 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)) needs to be installed.  
+An overview of Bluetooth LE sensors that are known to work with OpenTracks is in [README_TESTED_SENSORS.md](README_TESTED_SENSORS.md).
 
-## Custom Dashboards
+_Please note:_
+_OpenTracks_ does not contain a _map_ (as this would required Internet access).
+
+## Custom Dashboards (incl. Map)
 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).
+The developer documentation is in [README_API.md](README_API.md).
+
+Alternatively, recorded tracks can be shared as KMZ/GPX to installed applications (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)).
+However, this is rather slow and does not provide updates while recording.

@@ -7,22 +7,19 @@ 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.
+On the request of the user (i.e., pressing a button), an Intent is created that exposes the `Track` data (it's summary), the `TrackPoint`s, and the `Waypoint`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 is exposed,
+* 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 impossible, and
+* no write access is possible, and
 * neither track recordings can be started, paused, or stopped.
 
 All required information can be found in `IntentDashboardUtils.java`.
