这是我的舱单:
<service android:name=".fcm.PshycoFirebaseMessagingServices">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<service android:name=".fcm.PshycoFirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
当应用程序在后台和通知到达，然后默认通知来，不运行我的onmessagerreceived代码。
这是我的onMessageReceived代码。如果我的应用程序在前台运行，而不是在后台运行，就会调用这个函数。我怎么能运行这段代码时，应用程序是在后台太?
// [START receive_message]
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// TODO(developer): Handle FCM messages here.
// If the application is in the foreground handle both data and notification messages here.
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated. See sendNotification method below.
data = remoteMessage.getData();
String title = remoteMessage.getNotification().getTitle();
String message = remoteMessage.getNotification().getBody();
String imageUrl = (String) data.get("image");
String action = (String) data.get("action");
Log.i(TAG, "onMessageReceived: title : "+title);
Log.i(TAG, "onMessageReceived: message : "+message);
Log.i(TAG, "onMessageReceived: imageUrl : "+imageUrl);
Log.i(TAG, "onMessageReceived: action : "+action);
if (imageUrl == null) {
sendNotification(title,message,action);
} else {
new BigPictureNotification(this,title,message,imageUrl,action);
}
}
// [END receive_message]
发送消息的简单方法，即使应用程序是在后台和前台如下:-
要使用API发送消息，您可以使用一个名为AdvancedREST客户端工具，它是一个chrome扩展，并发送带有以下参数的消息。
Rest客户端工具链接:https://chrome.google.com/webstore/detail/advanced-rest-client/hgmloofddffdnphfgcellkdfbfbjeloo
使用这个url:- https://fcm.googleapis.com/fcm/send
内容类型:application / json
授权:key=您的服务器密钥或授权密钥(参见下面的参考)
{ "data": {
"image": "https://static.pexels.com/photos/4825/red-love-romantic-flowers.jpg",
"message": "Firebase Push Message Using API"
"AnotherActivity": "True"
},
"to" : "device id Or Device token"
}
授权密钥可以通过访问谷歌开发人员控制台，并单击项目左侧菜单上的凭证按钮来获得。在列出的API密钥中，服务器密钥将是您的授权密钥。
并且您需要将接收者的tokenID放在使用API发送的POST请求的“to”部分。
因为从Firebase通知UI发送的显示消息只在应用程序处于前台时有效。对于数据消息，需要对FCM进行POST调用
步骤
安装高级休息客户端谷歌Chrome扩展
添加以下头文件
关键字:Content-Type，值:application/json
密钥:授权，值:Key ="您的服务器密钥"
添加正文
如果使用主题:
｛
"to": "/topics/topic_name"，
"数据":{
"key1": "value1"，
"key2": "value2"，
｝
｝
如果使用注册id:
｛
"registration_ids": "[{"id"}，{id1}]"，
"数据":{
"key1": "value1"，
"key2": "value2"，
｝
｝
它!。现在像往常一样收听onmessagerreceived回调。
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Map<String, String> data = remoteMessage.getData();
String value1 = data.get("key1");
String value2 = data.get("key2");
}
根据文件
Handle messages in a backgrounded app
When your app is in the background, Android directs notification
messages to the system tray. A user tap on the notification opens the
app launcher by default.
This includes messages that contain both notification and data
payload. In these cases, the notification is delivered to the device's
system tray, and the data payload is delivered in the extras of the
intent of your launcher Activity.
If you want to open your app and perform a specific action, set
click_action in the notification payload and map it to an intent
filter in the Activity you want to launch. For example, set
click_action to OPEN_ACTIVITY_1 to trigger an intent filter like the
following:
<intent-filter> <action android:name="OPEN_ACTIVITY_1" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
编辑:
基于这个线程:
不能使用Firebase Console设置click_action有效负载。您可以尝试使用curl命令或自定义http服务器进行测试
curl --header "Authorization: key=<YOUR_KEY_GOES_HERE>"
--header Content-Type:"application/json" https://fcm.googleapis.com/fcm/send
-d "{\"to\":\"/topics/news\",\"notification\":
{\"title\": \"Click Action Message\",\"text\": \"Sample message\",
\"click_action\":\"OPEN_ACTIVITY_1\"}}"
我在firebase-messaging-sw.js中添加了以下代码，
messaging.onBackgroundmessage((payload)=>{
console.log("background message detected!!");
console.log("message : ", payload);
})
这是触发每次消息接收在后台。但我无法在主线程中使用有效负载，因为SW不支持它。所以我做了很多研究，在一个Android论坛上找到了一个解决方案。
因此，解决方案是必须从请求有效负载中删除通知有效负载。
所以我把有效载荷从
{
"notification": {
"title": "Hey there",
"body": "Subscribe to AMAL MOHAN N youtube channel"
},
"to": "your-browser-token",
"data": {
"value1": "text",
"value2": "",
"value3": "sample3",
"value4": "sample4"
}
}
to
{
"to": "your-browser-token",
"data": {
"value1": "text",
"value2": "",
"value3": "sample3",
"value4": "sample4"
}
}
有效负载的变化会自动在前台消息和后台消息中触发receiveMessage()。
我在一个Android论坛上发现了这个，这对我来说很有用!如果这对你有用，请告诉我。
