I have had my Samsung Galaxy S2 for a few weeks now and I have really enjoyed having a smartphone back in my pocket, after the demise of my iPhone.
Joining the Android Developer Program only cost $25 and I have now been experimenting with what I can get my phone to do.
A good starting point was to port ybsolo over to the Android Market. At the moment all the application does is open a web view but with the service being advertised in the market place, we hopefully will see some people trying it out.
Is My Train Delayed? is a perfect service for the mobile platform so I have been moving it to a native application. It is currently on the Android Market at version 4.0 as I have been adding features over the past few days.
Currently at 146 downloads, it is doing quite well. It pulls the live data straight from National Rail and creates a nice scrollable table view. It also auto-completes station names. On the website, you can locate your nearest station, I am experimenting with this on the android application as well as detailed journey information in a popup window.
