Version 0.0.5

March 19th, 2012 Posted in Version Update

Quite a few updates in this version:

Capture Route now has a Start/Stop Button at the top which will allow you to record routes as long as you like.


I’ve now implemented Display Routes, which can be accessed from SWR’s home screen once you have captured at least one route with Capture Route.

Display Routes will allow you to select the routes you want to see and it will draw them to screen in random colours. Unfortunately the colours are not stored, so every time you change your selections the colours will be randomly changed.


The route selection is done with this alert dialog which is set to always appear in the top right corner of the screen. This is to allow users on larger devices like Android Tablets to see the changes they are making on the map while they are making them.

These choices are persistently stored in Android’s Shared Preferences as characters in a String, which is my way of getting around the fact that Android does not allow arrays to be stored in Shared Preferences.

Please give Version 0.0.5 a go and let me know if you run into any issues.

If you are interested in how this application works please follow the link to GitHub on the right-hand side of the screen. The full source-code is available there. If any part of it is unclear to you, please let me know.


  • Capture Route has no way of stopping itself yet, and there is no notification to tell you it is running in the background. If you have it running you will see the icon to tell you that GPS is running.
  • I’m not filtering or smoothing the routes when placing them on the map, so you will see some very low-accuracy data and jagged, indirect lines.
  • Later on I’m going to be changing this so all routes will have a target and the data you record with this version will have to be discarded, so don’t record anything you want to keep forever!

What’s Next:

  • I need to work on getting information about the routes to pop-up when you tap on them.
  • I’ll also be looking at cleaning up the routes when they are displayed. (I think not displaying the very poor accuracy fixes will be a good starting place).
