In the google app invites guide (https://developers.google.com/app-invites/android/guides/app), we are asked to put the following meta-data tag in the android manifest:
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
In the sample's android manifest, we cannot see this tag anywhere:
Is there an error in the guide?
