我正在尝试使用FireBase云消息传递.我收到一个令牌,但它没有从控制台收到任何通知.这是我的清单:

  <?xml version="1.0" encoding="utf-8"?>

    android:minSdkVersion="16"
    android:targetSdkVersion="23" />

<android:uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

<application
    android:hardwareAccelerated="true"
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:supportsRtl="true">
    <activity
        android:name=".MainActivity"
        android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale"
        android:label="@string/activity_name"
        android:launchMode="singleTop"
        android:theme="@android:style/Theme.DeviceDefault.NoActionBar"
        android:windowSoftInputMode="adjustResize">
        <intent-filter android:label="@string/launcher_name">
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <service
        android:name=".TokenService">
        <intent-filter>
            <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
        </intent-filter>
    </service>
    <service
        android:name=".NotificationService">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT"/>
        </intent-filter>
    </service>
</application>

而我的代码几乎与样本相同:

public class NotificationService extends FirebaseMessagingService {

private void …

我注意到Firebase API已从v 9.0.0升级到v 9.0.1,因此决定更改它.

然而,它没有被注意到.

这是Gradle Logcat中的错误

   Error:(25, 13) Failed to resolve: com.google.firebase:firebase-messaging:9.0.1
   Error:(26, 13) Failed to resolve: com.google.firebase:firebase-core:9.0.1

这是我的Gradle文件
