This is the final tutorial part for developing simple PhoneGap based mobile application from the ground up. Earlier in tutorial parts one, two and three we took a closer look at what role PhoneGap hybrid mobile development framework plays in mobile development and how it works. We have created a new project and added several elements of functionality, similar to what most mobile applications out there would have – user interface, HTTP communication, data storage, native controls etc. In this final part I’m going to show you Geolocation API implementation, how to prepare and delay application splash screen and finalize everything with application icon. We’ll be working with the code from the last tutorial part (you can find at the bottom of tutorial part 3). Source code for overall finished PhoneGap application example (including today’s changes) can be found at the bottom of this post. Lets get started!
