CarbonFootPrint as a mobile app

[boro741]

CarbonFootPrint as a mobile app would help people to get awareness how much amount of Carbon they are emitting while travelling.

It would be nice to use the user's location.

I imagine that we could try to figure out (or ask the user) whether he/she is moving by car, bicycle or public transportation and poll his location every few seconds and use the distance travelled to estimate the CO2 emissions. We could show update the CO2 emissions in real time! That could be very impactful. Such an app would be independent of (and different from) the browser extensions.

This could be quite relevant

Interesting, @Kolpa !

I'm thinking of building with nativescript https://www.nativescript.org/

[Zahnentferner]

Nativescript seems to be a good option. Are there any competing alternatives?

[boro741]

yeah. React native http://facebook.github.io/react-native/docs/getting-started.html .

[Zahnentferner]

What are the advantages and disadvantages of each?

[boro741]

Both supports the native API's.
What I think the advantage of Native Script is that we can easily build with JavaScript.
For React Native it requires knowledge of react.js.

Or,
We can go with java but it wouldn't be supporting on cross platform.

Hi @ceilican,

The app would be great addition to the project!

It would be nice to use the user's location.

I have a slightly different approach to how we may be able to accomplish this. The official Google Maps app from Google tracks down the entire location data of every person and shows a summary of the person's day in the "Your Timeline" pane. I think we may be able to retrieve this data through their APIs. The best part of this would be that we wouldn't have to worry about whether the user is walking, driving or using public transport since we would be relying on Google's efficient algorithms.

Let me know what do you think about this.

[Zahnentferner]

So, it seems that we have three ways of getting the information we need:

1. extracting the information we need from Google Maps app (assuming that it could be done somehow), as suggested by @heychirag .

2. using the Activity Recognition API suggested by @Kolpa .

3. polling location data ourselves and doing the activity recognition and time and distance measurements ourselves.

Regarding option 1: can it be done? Does Google Maps API really make all that information available to other apps?

Regarding option 2: it is clear that the API recognizes the current activity for us. But does it also keep track of time and distance spent on each activity? Or would we have to do that ourselves?

Which of these two solutions is more likely to require less maintenance in the long term?

[Kolpa]

Regarding option one: this would be great but as far as I know Google does not allow for that kind of access to the data.
As far as option two is concerned we would need to do our own tracking from the point where the activity changes to driving untill it goes back to something else.
Maintenance should not be a huge requirements since the Android API doesn't really deprecate old functions all that fast and the activity detection is very new anyways.

Sorry for the accidental close I hit close and comment accidentally when writing this on mobile

what is "qfdws"?

[Kolpa]

That was not intended sorry about that I edited the original comment
