            buildConfigField "String", "BLE_SSID", STAGING_SERVICE_UUID

            String ssid = STAGING_SERVICE_UUID
            versionNameSuffix "-debug-${getGitHash()}-${ssid.substring(ssid.length() - 5,ssid.length() - 1 )}"
            resValue "string", "app_name", "Wiqaytna"
            applicationIdSuffix "stg"
        }

Firebase and google-services.json

Setup Firebase for the different environment. Download the google-services.json for each of the environments and put it in the corresponding folder.

The app currently relies on Firebase Functions to work. More information can be obtained by referring to opentrace-cloud-functions.

Remote Config

Security Enhancements

SSL pinning is not included as part of the repo. It is recommended to add in a check for SSL certificate returned by the backend.
