我想取回我的 token ,我正在做很多例子所说的在 FirebaseMessagingService 我有这个

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

我得到了错误

Method does not override method from it's superclass

当然 super.onNewToken(token)错误

cannot resolve method

在我的 ma​​inactivity 中,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:

Cannot resolve getInstanceId()

无法解析 InstanceIdResult

不能 解析 getToken()

并且方法不会覆盖它的方法

superclass

更新

类声明

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());
}
}
}

依赖关系

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

更新 v2

public class FirebaseMessagingService extends com.google.firebase.iid.zzb {
private static final java.util.Queue<java.lang.String> zzoma;

public FirebaseMessagingService() { /* compiled code */ }

@android.support.annotation.WorkerThread
public void onMessageReceived(com.google.firebase.messaging.RemoteMessage remoteMessage) { /* compiled code */ }

@android.support.annotation.WorkerThread
public void onDeletedMessages() { /* compiled code */ }

@android.support.annotation.WorkerThread
public void onMessageSent(java.lang.String s) { /* compiled code */ }

@android.support.annotation.WorkerThread
public void onSendError(java.lang.String s, java.lang.Exception e) { /* compiled code */ }

@com.google.android.gms.common.internal.Hide
protected final android.content.Intent zzp(android.content.Intent intent) { /* compiled code */ }

@com.google.android.gms.common.internal.Hide
public final boolean zzq(android.content.Intent intent) { /* compiled code */ }

@com.google.android.gms.common.internal.Hide
public final void handleIntent(android.content.Intent intent) { /* compiled code */ }

static void zzr(android.os.Bundle bundle) { /* compiled code */ }

static boolean zzal(android.os.Bundle bundle) { /* compiled code */ }

最佳答案

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>

将您想要获得 token 的 Activity 添加到您的 Activity 中:

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