Collecting Lat-Long in a Google Docs Form by adding script?

So I need am trying to figure out a way to collect Lat long data and have it saved automatically when I fill a Google form on my phone. Is it possible as retracing address to plot is not possible for my use case.

I am trying the solution mentioned by Sameer in this Quora post but completely unable to make this code work. It doesn’t have to be a Google form solution but an Open source solution which doesn’t restrict my data to its platform might also work.
