The license key is delivered as an XML file called augumenta_sdk_license.xml. This file needs to be saved in the Resource Values (..res/values) folder of your Android project module.

Your application will fail to run properly if the license key is not present at build time. You also need to check/add the following line in your AndroidManifest file, within the <application> element
(see App Manifest <application>), to ensure that the Augumenta SDK is able to access the license key:

  android:name="com.augumenta.aip.LicenseKey" android:value="@string/augumenta_sdk_license_key"
