当应用程序处于后台状态时，Google FCM getIntent未返回预期的数据

Question

{
 "data": {
  "body": "here is body",
  "title": "Title",
  "click_action": "YOUR_ACTION"
 },
 "to": "ffEseX6vwcM:APA91bF8m7wOF MY FCM ID 07j1aPUb"
}

<activity
            android:name=".NotificationActivity"
            android:screenOrientation="portrait"
            android:theme="@style/Theme.AppCompat.Dialog"
            android:windowSoftInputMode="stateHidden" >

            <intent-filter>
                <action android:name="YOUR_ACTION" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>

Bundle bundle=getIntent().getExtras();
        if(bundle!=null) {
            for (String key : bundle.keySet()) {
                Object value = bundle.get(key);
                Log.d("DATA_SENT", String.format("%s %s (%s)", key,
                        value.toString(), value.getClass().getName()));
            }
        }

collapse_key:com.myapp.package_name

但我预期的通知数据在哪里？

以下是我的系统配置：

Android Studio版本:2.1.3

Google Play服务版本:com.Google.android.gms:play-services:9.2.1

null

{
 "data": {
  "body": "here is body",
  "title": "Title"
 },
"notification": {
  "body": "here is body",
  "title": "Title",
  "click_action": "YOUR_ACTION"
 },
 "to": "ffEseX6vwcM:APA91bF8m7wOF MY FCM ID 07j1aPUb"
}

通知消息：通知消息在后台或前台工作。当app在后台时，通知消息会传递到系统托盘。如果应用程序在前台，则消息由onMessageReceived（）或didReceiveRemoteNotification回调处理。这些实质上就是所谓的显示消息。
