Question

我第一次使用FCM。在我的第一个实现中，我使用了以下approach。我收到的通知很完美。现在，我已经更新了我的应用程序，并尝试使用以下更新的approach。但是我面临的问题是，当我从通知控制台发送通知时，仍在使用以前版本的通知。

我已将Gradle更新为

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

    compile('com.crashlytics.sdk.android:crashlytics:2.9.5@aar') {
        transitive = true;
    }
    compile 'com.android.support:appcompat-v7:26.+'
    compile 'com.android.support:design:26.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.android.support:cardview-v7:26.+'
    compile 'com.android.support:support-v4:26.+'
    compile 'com.google.firebase:firebase-core:16.0.4'
    compile 'com.google.android.gms:play-services-ads:15.0.1'
    compile 'com.google.firebase:firebase-messaging:17.3.3'
    testCompile 'junit:junit:4.12' } apply plugin: 'com.google.gms.google-services'
}

第二个问题是当我在MainActivity.java的oncreate方法中使用此方法来检索新令牌时，java getToken（）和getActivity（）变成红色。

 FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener(this, instanceIdResult -> {
                    String newToken = instanceIdResult.getToken();
                    Log.e("newToken", newToken);
                    getActivity().getPreferences(Context.MODE_PRIVATE).edit().putString("fb", newToken).apply();
                });

                Log.d("newToken", getActivity().getPreferences(Context.MODE_PRIVATE).getString("fb", "empty :("));

我无法解决问题。请帮忙！

这是我的服务

public class MyFirebaseMessagingService extends FirebaseMessagingService {



    private static final String TAG = "FCM Service";

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        // TODO: Handle FCM messages here.
        // If the application is in the foreground handle both data and notification messages here.
        // Also if you intend on generating your own notifications as a result of a received FCM
        // message, here is where that should be initiated.
        Log.d(TAG, "From: " + remoteMessage.getFrom());
        Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
    }

    public void onNewToken(String token) {
        Log.d(TAG, "Refreshed token: " + token);

        // 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.
        sendRegistrationToServer(token);
    }
    private void sendRegistrationToServer(String token) {
        // TODO: Implement this method to send token to your app server.
    }

}

FCM正在向我的旧版本应用发送通知，但未发送更新版本的通知
