Calculate driving distances with AI2

[Fernando Silveira]

Hi guys,

I'm trying to develop a simple app to calculate distance and travel duration from point A to B.

I was looking on other posts here and many of them direct us to WHERE IS MY CAR app and/or to look for google APIs (https://developers.google.com/maps/documentation/directions/).

The fact is, I have lots of doubts...

1st of all) I didn't find the similar info that ActivityStarter will use in google API page, are they the same used in WHERE IS MY CAR APP?

Action =  android.intent.action.VIEW

ActivityClass = com.google.android.maps.MapsActivity

ActivityPackage =  com.google.android.apps.maps

2nd) Considering I'm able to set up the correct URL to activate Google API, how do I process its response? I mean, how do I extract from the response the info I need (distance and trip duration) ?

Hope you can help me here.

Regards,

Fernando

see these threads https://groups.google.com/forum/#!searchin/mitappinventortest/Google$20Maps$20API$20distance and use the web component to access one of the Google Maps APIs

That's exactly what I want to create using AI2. Where do I start?

I have used the 'great circle formula' with lat,lon coordinates to calculate distance in a project here.
