Question

实际上，我正在尝试通过点击activity将意图传递给push-notification，当应用程序出现在foreground时，它正常工作。但是当应用程序处于后台时虽然我收到push-notification但没有任何问题，但是通过点击该通知我没有意图activity。我尝试在SO中引用一些问题并尝试添加PendingIntent.FLAG_UPDATE_CURRENT之类的标记， PendingIntent.FLAG_ONE_SHOT，然后是意图(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_SINGLE_TOP )，但没有一个是有用的。请帮助我解决这个问题，这是过去两天的痛苦。

的Manifest.xml：

<activity android:name=".activities.ProfileHolder"
        android:windowSoftInputMode="adjustPan"
        android:screenOrientation="portrait"
        android:exported="true"
        android:launchMode="singleTop"
       >
        <intent-filter>
            <action android:name="profile" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

Node.js中的通知代码：

var message = {
         to: u.fcm_token, 
         collapse_key: 'white', //anything can be given
         data: {
             type:"likes",
             post_owner_username:data.like_post_owner_username,
             owner_post_time:data.like_post_owner_time

         },
         priority: 'high',
         notification: {
             title: 'Infinity',
             body:notif_data,
             sound: "default",
             click_action: "profile",
             tag:"Hey Bro" //if specified then current msg would be  replaced by new msg
         }
     };

     fcm.send(message, function(err, response){
         if (err) {
             console.log(err);
         } else {
             console.log("Successfully sent with response: ", response);
         }
     });

FirebaseMessagingService类：

/Varibales for notifications
String title, body, post_owner_username, post_owner_time, notif_commenter_username, notif_comment_time, follower_username,messager_username,type,action;
@Override

    title=remoteMessage.getNotification().getTitle();
    body=remoteMessage.getNotification().getBody();
    type=remoteMessage.getData().get("type");
    action=remoteMessage.getNotification().getClickAction();

    Log.d("type",type);
    Log.d("type-2",title);

   if(type.equals("likes")){
       post_owner_username=remoteMessage.getData().get("post_owner_username");
       post_owner_time=remoteMessage.getData().get("owner_post_time");

我认为问题是因为您正在从fcm控制台发送通知！

来自文档

“当您的应用在用户设备的后台时，通知被送到系统托盘。当用户点击时通知，应用启动器会打开您的应用。如果你愿意，你可以还添加客户端消息处理以在您的应用程序中接收通知当它已经在用户设备的前台时。“

您应该尝试使用Fcm apis发送通知

<强>假设我认为你使用api时不应该发送通知参数只发送数据参数并解析onMessageReceived中的数据如果你发送通知它会传递到系统托盘

为什么onMessageReceived（）方法在应用程序处于后台时没有正确传递意图？
