Question

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
