當活動處於後臺時，Firebase通知不起作用

我擁有與Firebase示例代碼提供的代碼相同的代碼。當活動處於前景狀態或打開狀態時，它可以正常工作。但是，當活動關閉或在後臺狀態下，它不能正常工作。問題就是這樣...當活動處於後臺時，Firebase通知不起作用

應用程序圖標未顯示應用程序。
默認情況下采取的應用程序名稱的通知標題

當應用程序在後臺狀態或當時通知時再logcat的設備沒有打開顯示以下信息：

09-16 15:55:56.056 12113-12113/com.testdemofb D/FirebaseApp: com.google.firebase.auth.FirebaseAuth is not linked. Skipping initialization. 
09-16 15:55:56.089 12113-12113/com.testdemofb D/FirebaseApp: com.google.firebase.crash.FirebaseCrash is not linked. Skipping initialization.

09-16 15:55:56.518 12113-12147/com.testdemofb I/FA: Tag Manager is not found and thus will not be used

如果有任何解決方案，然後幫助我

謝謝...

    NotificationManager notificationManager = 
      (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build()); 

} 
}

AndroidManifest.xml文件把這樣應用之間標籤...

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

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

你能分享你的執行生成notofication –

分享我的代碼生成通知@ RaguSwaminathan –

你檢查是否調用sendnotification方法嗎？？嘗試在那裏記錄和檢查 –

有兩種類型的FCM使用的消息，即。通知和數據。閱讀更多關於它here。我認爲你正在發送通知。您需要發送數據信息。

就是這樣。從火力地堡控制檯

{ 
"to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...", 
    "data" : { 
"Nick" : "Mario", 
"body" : "great match!", 
"Room" : "PortugalVSDenmark" 
}, 
}

發送通知：同時適用於背景和前景應用

相反onMessageReceived的，覆蓋ZZM（）FirebaseMessagingService，並從這裏創建自定義通知

@Override 
public void zzm(Intent intent) { 
    Log.e(TAG, "zzm : " + intent); 
    createNotification();   
} 

@Override 
public void onMessageReceived(RemoteMessage remoteMessage) { 

}

zzm方法到底做了什麼？它是好的做法重寫它？ – Vlad

我想FireBase是這樣工作的...
