Question

我有一段时间没有编程android了，我发现Firebase消息传递服务已被弃用。我实现了新的FirebaseMessagingService类，并且重写了onNewToken以获得令牌，但是该方法甚至没有被调用，因为文档中说该方法应自动运行。但是现在我很困惑，为什么不生成令牌？这是我实现的

public class FireBsaeTest extends FirebaseMessagingService {
    public FireBsaeTest(){
    }
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {

        if (remoteMessage.getData().size() > 0) {

            } else {

            }

        }


        if (remoteMessage.getNotification() != null) {
        }

    }
    @Override
    public void onNewToken(String token) {
        System.out.println(token);

    }}

这是清单

 <service android:name=".FireBsaeTest">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT" />
            </intent-filter>
        </service>

我想念什么吗？

更新

我尝试从我的活动中手动调用它，以阻止新的非法异常firebaseNotInilized

 FirebaseApp.initializeApp(this);
        FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener(new OnSuccessListener<InstanceIdResult>() {
            @Override
            public void onSuccess(InstanceIdResult instanceIdResult) {
                System.out.println(instanceIdResult.getToken());
            }
        });

Answer 1

我只知道问题出在哪里，问题在于使用类路径实施根build.gradle文件，android studio像下面这样配置依赖项

dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'
        classpath 'com.google.gms:google-services:4.1.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

应将Google-services配置为classpath 'com.google.gms:google-services:4.0.1' 一旦我更改了班级路径，它就可以工作了，现在无法获取令牌

MyFirebaseMessagingService

 public class MyFirebaseMessagingService extends FirebaseMessagingService {
        private static final String TAG = MyFirebaseMessagingService.class.getSimpleName();


        @Override
        public void onNewToken(String s) {
            super.onNewToken(s);
            Log.i(TAG, "onNewToken:    >>>  " + s);
        }
     @Override
        public void onMessageReceived(RemoteMessage remoteMessage) {
           }
    }

MyFirebaseInstanceIDService.java

 public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
        @Override
        public void onTokenRefresh() {
            String refreshedToken = FirebaseInstanceId.getInstance().getToken();
            Log.d("FirebaseInstanceID", "Refreshed token: " + refreshedToken);

            // Notify UI that registration has completed, so the progress indicator can be hidden.

        }
    }

Manifest.xml

    <service   android:name=".services.MyFirebaseMessagingService"
 android:exported="false"
  android:stopWithTask="false">
    <intent-filter>
       <action android:name="com.google.firebase.MESSAGING_EVENT"/>
                </intent-filter>
            </service>
            <service
                    android:name=".services.MyFirebaseInstanceIDService"
                    android:exported="false">
                <intent-filter>
                    <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
                </intent-filter>
            </service>

成绩

implementation 'com.google.firebase:firebase-core:16.0.6'
implementation 'com.google.firebase:firebase-messaging:17.3.4'
