API keys required for testing EVMap
===================================

EVMap uses multiple different data sources, most of which require an API key. These API keys need to
be put into the app in the form of a resource file called `apikeys.xml` under
`app/src/main/res/values`, with the following content:

<details>
<summary>apikeys.xml content</summary>

```xml

<resources>
   <string name="google_maps_key" templateMergeStrategy="preserve" translatable="false">
      insert your Google Maps key here
   </string>
   <string name="mapbox_key" translatable="false">
      insert your Mapbox key here
   </string>
   <string name="jawg_key" translatable="false">
      insert your Jawg Maps key here
   </string>
   <string name="arcgis_key" translatable="false">
      insert your ArcGIS Maps key here
   </string>
   <string name="goingelectric_key" translatable="false">
      insert your GoingElectric key here
   </string>
   <string name="chargeprice_key" translatable="false">
      insert your Chargeprice key here
   </string>
   <string name="openchargemap_key" translatable="false">
      insert your OpenChargeMap key here
   </string>
   <string name="fronyx_key" translatable="false">
      insert your Fronyx key here
   </string>
   <string name="acra_credentials" translatable="false">
      insert your ACRA crash reporting credentials here
   </string>
</resources>
```

</details>

Not all API keys are strictly required if you only want to work on certain parts of the app. For
example, you can choose only one of the map providers and one of the charging station databases. The
Chargeprice API key is also only required if you want to test the price comparison feature.

Most APIs can be used for free, at least for testing. Some APIs require payment above a certain
usage limit or to get access to the full dataset, but the free tiers should be plenty for local
testing and development.

Below you find a list of all the services and how to obtain the API keys.

Map providers
-------------

The different Map SDKs are wrapped by our [fork](https://github.com/ev-map/AnyMaps) of the
[AnyMaps](https://github.com/sharenowTech/AnyMaps) library to provide a common API. The `google`
build flavor of the app includes both Google Maps and OpenStreetMap (vector tiles from
[Jawg Maps](https://www.jawg.io/en/) through [MapLibre](https://maplibre.org/)) and allows the user
to switch between the two, while the `foss` flavor only includes OSM.

> ⚠️ When testing the app using the Android Emulator, we recommend using Google Maps and not
> OSM/MapLibre, as the latter has
[issues displaying the markers](https://github.com/mapbox/mapbox-gl-native/issues/10829). It works fine on real Android devices.

### Google Maps

[Maps SDK for Android](https://developers.google.com/maps/documentation/android-sdk/overview),

3. Under *APIs & Services → Library*, enable
   the [Maps SDK for Android](https://console.cloud.google.com/apis/library/maps-android-backend.googleapis.com)

Pricing providers
-----------------

### Chargeprice.app

[API documentation](https://github.com/chargeprice/chargeprice-api-docs)

<details>
<summary>How to obtain an API key</summary>

Since February 2022, the Chargeprice API is no longer available for free to new customers. However,
you can use their
[staging API](https://github.com/chargeprice/chargeprice-api-docs/blob/master/test_the_api.md)
for free to test the Chargeprice features. This is already
[configured](https://github.com/ev-map/EVMap/blob/master/app/src/debug/res/values/donottranslate.xml)
by default for the debug version of the app, so you can leave the `chargeprice_key` field in your
new `app/src/main/res/values/apikeys.xml` file blank. Note that the staging API contains only a
limited dataset, so it only outputs prices for certain charge point operators and payment plans (see
[here](https://docs.google.com/document/d/14zlFr5IEhhR3uGXO5QePKjNUQANVwA-Ba-cZbOCiOBk/edit) for
details).

In case you want to pay for access to the full Chargeprice API, check out their
[API docs](https://github.com/chargeprice/chargeprice-api-docs) on GitHub and contact them at
[sales@chargeprice.net](mailto:sales@chargeprice.net).
</details>

Availability data providers
---------------------------

### fronyx

[fronyx](https://fronyx.io/) provides us predictions of charging station availability.

<details>
<summary>How to obtain an API key</summary>

The API is not publicly available, contact [fronyx](https://fronyx.io/contact-us/) to get an API
key and documentation.

If you don't want to test this functionality, simply leave the API key blank.
</details>

Crash reporting
---------------

Crash reporting for release builds is done using [ACRA](https://github.com/ACRA/acra).
This should not be needed for debugging.
If you still want to try it out, you can host any compatible backend such as
[Acrarium](https://github.com/F43nd1r/Acrarium/) yourself.
