问题
I am implementing push notifications in Android with Firebase Cloud Messaging, and I am implementing Facebook Push Notifications and Facebook In-App Notifications too.
I am following the instructions at https://developers.facebook.com/docs/push-notifications/android to set up Push Campaigns for Android. I already completed the instructions at https://firebase.google.com/docs/cloud-messaging/android/client for setting up a Firebase Cloud Messaging Client App on Android.
This is the content of my MyFirebaseMessagingService.java file:

import android.util.Log;
import com.facebook.notifications.internal.appevents.AppEventsLogger;

private static final String TAG = "MyFirebaseIIDService";

// [START refresh_token]
@Override
public void onTokenRefresh() {
try {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
AppEventsLogger.setPushNotificationsRegistrationId(refreshedToken);
Log.d(TAG, "Refreshed token: " + refreshedToken);
// If you want to send messages to this application instance or
// manage this apps subscriptions on the server side, send the
// Instance ID token to your app server.

System.out.println("Registration.onTokenRefresh TOKEN: " + refreshedToken );
} catch (Exception e) {
Log.e("test", "Failed to complete token refresh", e);
}
}
// [END refresh_token]

}
}
This is the line that is generating an error for me:
AppEventsLogger.setPushNotificationsRegistrationId(refreshedToken);
The error is: Cannot resolve method 'setPushNotificationsRegistrationId(java.lang.String)' and you can see it in the following image:
I thought the Facebook libraries should already be taking care of importing that method. I am using compile 'com.facebook.android:facebook-android-sdk:3.23.1' in my dependencies and also compile 'com.facebook.android:notifications:1.+'. Do you have any ideas about what may be causing this error? Maybe I need a newer version of the Facebook SDK? I will appreciate any hints and ideas to fix this error. Thank you.
EDIT 1: I already tried using compile 'com.facebook.android:facebook-android-sdk:4.20.0', but I still see the same error.
EDIT 2: I found the following information at https://developers.facebook.com/docs/android/change-log-4x:
4.11.0 - April 12, 2016 Facebook SDK Added AppEventsLogger.setPushNotificationsRegistrationId and AppEventsLogger.logPush*.
That means that AppEventsLogger.setPushNotificationsRegistrationId did not exist before Facebook SDK 4.11.0, and I am using Facebook SDK 3.23.1. It makes sense that the method setPushNotificationsRegistrationId() is not recognized. But why is it that even when I use compile 'com.facebook.android:facebook-android-sdk:4.11.0' in my dependencies and try to compile the app, I still see the same error?
EDIT 3: I am examining the documentation at https://developers.facebook.com/docs/reference/android/current/class/AppEventsLogger/ to learn more about the AppEventsLogger class, and I can see that the setPushNotificationsRegistrationId(String) method is listed with the following description: Sets a registration id to register the current app installation for push notifications. What I am using to have access to this class and method is: import com.facebook.notifications.internal.appevents.AppEventsLogger;. I do not see at https://developers.facebook.com/docs/reference/android/current/class/AppEventsLogger/ any restrictions or documentation about a minimum Facebook SDK or additional requirements to be able to use the setPushNotificationsRegistrationId() method that I was expecting to have available from the class AppEventsLogger that I am using.
EDIT 4: In order to use AppEventsLogger.setPushNotificationsRegistrationId(refreshedToken);, do I need to import import com.facebook.notifications.internal.appevents.AppEventsLogger; or import com.facebook.AppEventsLogger;? In other portions of my code, I have used for example AppEventsLogger logger = AppEventsLogger.newLogger(getApplication()); with import com.facebook.AppEventsLogger;. What would be the difference between using import com.facebook.notifications.internal.appevents.AppEventsLogger; versus import com.facebook.AppEventsLogger;? Thank you.
回答1:
The setPushNotificationsRegistrationId() method did not exist in Facebook SDK 3.23.1: https://developers.facebook.com/docs/reference/android/3.23.1/class/AppEventsLogger/. It was introduced from Facebook SDK 4.11: https://developers.facebook.com/docs/reference/android/4.11/class/AppEventsLogger/ and https://developers.facebook.com/docs/android/change-log-4x.
