Que diriez-vous de faire votre application accepte des liens spécifiques, par exemple

<data android:pathPrefix="www.example.com" android:scheme="http"/> 

Ensuite, vous envoyez un lien, par ex. http://www.example.com/abcd, à l'e-mail et l'utilisateur devrait l'ouvrir avec l'application, à la fin de l'application va vérifier si le lien "lien ouvert" est le même que le "lien envoyé".
