* through its manifest (in other words, Universal Links, deep linking). Anyway,
* we need a hardcoded list because it has proven impossible to programmatically
* read the information out of the app's manifests: App Store strips the
* associated domains manifest out of the app so it's never downloaded on the
* client and we did not spend a lot of effort to read the associated domains
* out of the Andorid manifest.
