 # HW2
 
-Deadline: **22.03.2020 23:59:59**  
+SporMaps App
+
+Deadline - final deadline - end of semester
+
+
+App like endomondo, nike run, strava, runtastic, etc.
+
+General idea - app, that would help you in unknown terrain with navigation and training.
+App is based on Google Maps (or openstreetmap or some other) and built-in GPS functionality.
+
+
+
+Display map, and update your location on map display. 
+Allow toggling of "keep map constantly centered", "keep north-up / direction up / user chosen-up".
+
+When tracking is started, start to draw trail from start to current location. 
+Allow user to set checkpoints (permanent) and waypoints (single) on track. Ie when adding new waypoint, remove previous. 
+Calculate and display direct and travelled distance from start, last checkpoint and last waypoint.
+Time elapsed from start, pace (in minutes per km) overall in every three sections.
+
+Save all the sessions and all the checkpoints to database. 
+Allow user to view/delete old sessions - display statistics and track on map.
+
+
+For controlling the app from lock screen, implement sticky custom layout notification - UI similar to what you have under the map.
+When user stops session, ask for confirmation. Do not let to start/stop session from lockscreen.
+Constantly(after every position update)  update notification to display current info - distances and pace. 
+
+GPS listener and notification intents broadcastlistener has to be implemented in service, 
+otherwise app cannot be kept running in background.
+
+
+App has to support rotation (and state has to be restored) - move buttons from bottom to left-or-right screen edge in landscape mode.
+
+Provide on-screen real compass (must be possible to turn on-and-off). Not the google maps rotation indicator.
+
+Provide session export possibility - ie as email attachment for example. File format - gpx.
+https://www.topografix.com/gpx_manual.asp (checkpoints as waypoints gpx format).
+gpx entries hav to contain coordinates and timestamp (for later track analysis and animation).
+
+Change app icon into something more meaningful.
+
+ 
+Final testing of your app will happen in real life () - using paper map and your app 
+find hidden checkpoints in terrain - take photo of every cp and present these and your track (sent as email attachment to teacher) at the end.
