Extract java library for the data-collection

[TheoAk]

Hello,

I'm the intern working in Lyon.
I tried to analyse this repository you send me to create an external library to use with our app but I did not understand where the functions are called in the application.
Could you tell me the steps to extract the android part or how the functions are called and used in the app ?

Thank you

@TheoAk this is a cordova plugin (sort of like a flutter plugin, but older). The interface is defined in
https://github.com/e-mission/e-mission-data-collection/blob/master/src/android/DataCollectionPlugin.java

It is called from the javascript in the phone UI code - e.g. markConsented is called here
https://github.com/e-mission/e-mission-phone/blob/3caed98bd8f6843d7311fdd48e00f9b376ce91f0/www/js/splash/startprefs.js#L32

What are you writing your app in?

Also, as I pointed out, you don't need to write a separate app to test out various settings, you can set them directly from the core phone UI (Profile -> Developer Zone). We might want to have a short chat to orient you with the phone architecture to make the most efficient use of your time.

What are you writing your app in?

If the answer is "java", then @ericafenyo from Transway has packaged this as a library and built a native app.
Please see e-mission/e-mission-docs#621 (comment) for some indications of how he accomplished that.

Thank you for the clarifications.

Cozy is creating an app (in React Native) with many features and this library based on this repo could be used with the app to have a start of tracking user's trips.

@TheoAk

The interface to this plugin is currently defined in
https://github.com/e-mission/e-mission-data-collection/blob/master/www/datacollection.js

It is implemented in android at
https://github.com/e-mission/e-mission-data-collection/blob/master/src/android/DataCollectionPlugin.java

and on iOS at
https://github.com/e-mission/e-mission-data-collection/blob/master/src/ios/BEMDataCollection.m

This implementation is for cordova.

You should be able to re-implement the interface in React Native, and then you can use the plugin.
Or maybe this is useful?
https://www.npmjs.com/package/react-native-cordova-plugin

@TheoAk I should point out that this plugin is fairly tightly coupled with other plugins to cache the data locally. In particular, the code to determine whether we need to turn off tracking reads data from the local cache to see how much we have moved recently. You should look at the other plugins under the e-mission-phone repo as well.
