I am developing an app with which, the user can input the destination and a route from his current position to the destination will be shown on the google map. I searched online and found many tutorials in which they were using google map api javascript v3 . I also read the official documents from

https://developers.google.com/maps/articles/android_v3, https://developers.google.com/maps/documentation/directions/

But I am confused as

  • how are they using the javascript in their program.
  • how is XML /JSON working.
  • how is this program overall is working?

As what I understand that the methods defined in the above documents are related to a browser app, so how will it be launched from an android application?

And finally which is the best way/method/api to develop this app.

Lastly , I am not looking for the code ,as I will develop the code myself. I am just wanted to know that overall how these app/ google maps is working?

Thanks

  • does the source_latitude/longitude and the destination_latitude/longitude needs to be constant or the user can enter these values in a text box and I can replace the source_latitude/longitude and the destination_latitude/longitude with the user's value? – user1833186 Nov 26 '12 at 05:47
  • for these 4 variable you have to pass value for it. – Sanket Kachhela Nov 26 '12 at 05:49
  • will it work, if the user enters name of the cities instead of the coordinates? – user1833186 Nov 29 '12 at 02:56
