應用程序被殺/刷出時未收到FCM推送通知

Question

我正在從GCM向FCM遷移通知。 在GCM中，當應用程序處於前台，后台或被殺時，我能夠收到通知，但是在FCM中，當瀏覽器未打開/殺死應用程序時，我無法收到通知。 我錯過了什么????

AndroidManifest.xml中

    <service
        android:name=".Services.ExtendedInstanceIDListenerService"
        android:exported="false">
        <intent-filter>
            <action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
        </intent-filter>
    </service>
    <service
        android:name=".Services.FcmMessageHandler"           
        android:exported="false">

private void showNotificationMessage(Context context, String title, String message, Intent intent) {
    notificationUtils = new NotificationUtils(context);
    //intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
    intent.putExtra("message", message);
    //intent.putExtra("notification", "noti");
    notificationUtils.showNotificationMessage(title, message, intent);
}

/**

 */
private void showNotificationMessageWithBigImage(Context context, String title, String message, Intent intent, String imageUrl) {
    notificationUtils = new NotificationUtils(context);
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
    intent.putExtra("message", message);
    //intent.putExtra("notification", "noti");
    notificationUtils.showNotificationMessage(title, message, intent, imageUrl);
}

嘗試這個。 我是這樣做的。 使用NotificationUtils。 下面是NotificationUtils代碼
