Two API keys are needed for the application to function correctly, a DJI sdk key and a Mapbox key.
A DJI app key can be obtained by registering an application's bundle id at https://developer.dji.com/user/apps/#all. First, create an account or sign in. Next, press Create App, and fill in the required information. Then, press Create. The app key can be viewed by clicking on the SDK project. Copy and paste this key anywhere in the local.properties file in the format DJI_API_KEY=<YOUR KEY>.
A Mapbox token can be obtained by going to https://account.mapbox.com/ and creating an account. Next, create an access token by clicking Create Token. Leave the default's selected and for secret scopes, select MAP:READ. Then, press Create token. Copy this token anywhere into the local.properties file in the format MAPBOX_DOWNLOADS_TOKEN=<YOUR KEY>.
