我想在 Node.js 中使用 FCM 添加推送通知的东西。为此我试过这个

而这和也这样

我的 nodejs 代码

var FCM = require('fcm-node');

var serverkey = 'SERVERKEY';  
var fcm = new FCM(serverkey);
var message = {  
			to : req.body.userToken,
			collapse_key : 'XXX',
			data : {
					my_key: 'my value', contents: "abcv/"
			},
			notification : {
					title : 'Title of the notification',
					body : 'Body of the notification'
			}
	};

fcm.send(message, function(err,response){  
if(err) {
	console.log(message);
       console.log("Something has gone wrong !");
 } else {
     console.log("Successfully sent with resposne :",response); …

在我的 Android 应用程序中，我想将我的自定义对象传递给另一个活动。我正在使用 Intent

Intent i = new Intent(A.this,B.class); 
i.putExtra ("Object", myObject);
context.startActivity (i);

在调用活动中

 MyObject myObject = (MyObject) intent.getSerializableExtra ("Object");

我也在我的模型类中实现了 Serilizable。但是当我运行应用程序时它会显示

java.lang.RuntimeException: Parcelable 在写入可序列化对象时遇到 IOException

日志显示了这一点
