Je suis le tutoriel de Codelab sur firebase de l'application FriendlyChat. J'ai atteint la section Indexation. J'ai implémenté le code comme requis mais je ne vois pas l'indexation de l'application quand je recherche google sur l'émulateur.Mon Firebase L'indexation sur l'appareil ne fonctionne pas
Voici la section manifeste.
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW"/>
<category android:name="android.intent.category.DEFAULT"/>
<category android:name="android.intent.category.BROWSABLE"/>
<data
android:host="friendlychat.firebase.google.com"
android:scheme="http"
android:pathPrefix="/message"/>
</intent-filter>
Voici le MainActivity.java
Le tutoriel est sur cette page https://codelabs.developers.google.com/codelabs/firebase-android/#8
pourrait être le problème que j'utilise l'émulateur?
Voici le MainActivity.java
