## 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) 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 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`.
