Honor the default unit from the nutrient taxonomy

[Slawek234]

When we add a Vitamin, fats, macro- microelements the default unit should be selected.

Current situation. The default unit is gram.

After entering the automatic units for the different nutrients.

@Slawek234 can you file on https://github.com/openfoodfacts/openfoodfacts-server ?
I'd rather provide the nutrient translations as a downloadable file we can update on the fly. Also, the European Commission is making its translation memories available as opendata, so we'll be able to build on that.

I think this is already implemented in openfoodfacts-server.

@stefaniebosch and I would like to take our chance at this issue

[machiav3lli]

Here's our solution's idea:

1. Make sure that the JSON file (https://static.openfoodfacts.org/data/taxonomies/nutrients.json) is saved

   • download & parse it if not.

   • the default unit is provided currently in the form: "unit":{"en":"mg"}

   • this needs more deliberation to see, when the file should be pulled

2. In class ProductEditNutritionFactsFragment in function displayAddNutrientDialog()

3. get the defualt unit from the saved JSON data.

4. Get the correct index depending on the gotten value.

5. The index should be used as argument unitSelectedIndex in addNutrientRow().

Points to consider:

• The saved data from JSON can be possibly used in other places of the app

  • e.g. forcing the default unit in data view (to standardize the presentation and still allow users to easily make prefered input)

• Consider if the basic fields (fat, saturated fat, Carbohyrate, …) also has to have other values than gram.
