When the activity is launched by the link, it is passed an intent object containing data about the action which launched the activity including a Uri object containing the app link URL. Within the initialization stages of the activity, code can be added to extract this data as follows:

Intent appLinkIntent = getIntent();

String appLinkAction = appLinkIntent.getAction();

Uri appLinkData = appLinkIntent.getData();
