MyFirebaseMessagingService.java：public class MyFirebaseMessagingService extends FirebaseMessagingService { @Override public void onNewToken(String s) { Log.e("NEW_TOKEN", s); } @Override public void onMessageReceived(RemoteMessage remoteMessage) { Map<String, String> params = remoteMessage.getData(); JSONObject object = new JSONObject(params); Log.e("JSON_OBJECT", object.toString()); String NOTIFICATION_CHANNEL_ID = "Nilesh_channel"; long pattern[] = {0, 1000, 500, 1000}; NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) { NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "Your Notifications", NotificationManager.IMPORTANCE_HIGH); notificationChannel.setDescription(""); notificationChannel.enableLights(true); notificationChannel.setLightColor(Color.RED); notificationChannel.setVibrationPattern(pattern); notificationChannel.enableVibration(true); mNotificationManager.createNotificationChannel(notificationChannel); } // to diaplay notification in DND Mode if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) { NotificationChannel channel = mNotificationManager.getNotificationChannel(NOTIFICATION_CHANNEL_ID); channel.canBypassDnd(); } NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID); mNotificationManager.notify(1000, notificationBuilder.build()); }}跳過MainActivity 中的此代碼。我不知道該怎么辦。Firebase OAuth 完美運行。但是沒有令牌，我無法檢查 Firebase 通知?，F在是調試模式。也許我必須更改它才能發布？請幫我。

According to latest docs,you can get new token id from onNewToken Method.<br/>
@Override
public void onNewToken(String s) {
Log.e("NEW_TOKEN", s);
//Implement your business logic to send your device token from here
}

嘗試更改您的 addOnSuccessListener 方法，刪除第一個參數，如下所示：
FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener(new OnSuccessListener<InstanceIdResult>() {
@Override
public void onSuccess(InstanceIdResult instanceIdResult) {
//Manage your token
String token = instanceIdResult.getToken();
Log.i("FCM_TOKEN", token);
}
});

除了 FirebaseMessagingService 之外，還需要添加 FirebaseInstanceIdService
public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
public MyFirebaseInstanceIDService() {
}
@Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
MyNotificationManager.getInstance().registerToken(getApplicationContext(), refreshedToken);
}
}
然后在您的清單中添加：
<service
android:name=".MyFirebaseInstanceIDService"
android:enabled="true"
android:exported="true"/>
