重写onNewToken并从firebase错误中获取令牌

Question

我想检索我的令牌，我正按照许多例子所说的那样做在FirebaseMessagingService上，我有这个

@Override
public void onNewToken(String token) {
super.onNewToken(token);
Log.e("Refreshed token:",token);
}

我得到了错误

方法不会覆盖超类中的方法

当然super.onNewToken(token)具有错误

无法解析方法

在我的主活动上，我在OnCreate((中有这个

FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener( MyActivity.this,  new OnSuccessListener<InstanceIdResult>() {
@Override
public void onSuccess(InstanceIdResult instanceIdResult) {          
String newToken = instanceIdResult.getToken();    
}
});

我得到的错误是：

无法解析getInstanceId((

无法解析InstanceIdResult

不能解析getToken((

并且Method不会覆盖其中的方法

超类

更新

类别声明

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

@Override
public void onNewToken(String token) {
super.onNewToken(token);
Log.e("Refreshed token:",token);
}
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.e(TAG, "From: " + remoteMessage.getFrom());
if (remoteMessage == null)
return;
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
Log.e(TAG, "Notification Body: " + remoteMessage.getNotification().getBody());
handleNotification(remoteMessage.getNotification().getBody());
}
// Check if message contains a data payload.
if (remoteMessage.getData().size() > 0) {
Log.e(TAG, "Data Payload: " + remoteMessage.getData().toString());
try {
JSONObject json = new JSONObject(remoteMessage.getData().toString());
handleDataMessage(json);
} catch (Exception e) {
Log.e(TAG, "Exception: " + e.getMessage());
}
}
}

build.gradle(应用程序(：

implementation 'com.google.firebase:firebase-core:16.0.5'
implementation 'com.google.firebase:firebase-messaging:17.3.4'

扩展类：

package /*package name*/;
import android.util.Log;
import com.google.firebase.messaging.FirebaseMessagingService;
public class MyFcmListenerService extends FirebaseMessagingService {
/**
* Called if InstanceID token is updated. This may occur if the security of
* the previous token had been compromised. Note that this is also called
* when the Instance ID token is initially generated, so this is where
* you retrieve the token.
*/
@Override
public void onNewToken(String token) {
Log.d("TAG", "New token: " + token);
// TODO: Implement this method to send any registration to your app's servers.
sendRegistrationToServer(token); //As I understand it, you need to implement it yourself.
}
}

在AndroidManifest.xml的标签中：

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

添加到您想要获得代币的活动中：

FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener(MainActivity.this,  new OnSuccessListener<InstanceIdResult>() {
@Override
public void onSuccess(InstanceIdResult instanceIdResult) {
String newToken = instanceIdResult.getToken();
}
});
