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]
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\"}}"
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
}
不是每次调用它时,只有当应用程序是在前景
有一个覆盖方法,这个方法每次都会被调用,不管什么应用程序在前台,在后台或被杀死,但是这个方法在这个firebase API版本中可用
这是你必须从gradle导入的版本
compile 'com.google.firebase:firebase-messaging:10.2.1'
这就是方法
@Override
public void handleIntent(Intent intent) {
super.handleIntent(intent);
// you can get ur data here
//intent.getExtras().get("your_data_key")
}
在之前的firebase API中,这个方法是不存在的
当应用程序在后台....时,Fire base句柄本身现在你有了这个方法
无论你想做什么…你可以在这里用这个方法.....
如果您使用的是以前的版本,那么默认活动将启动
在这种情况下,你可以用同样的方法得到数据
if(getIntent().getExtras() != null && getIntent().getExtras().get("your_data_key") != null) {
String strNotificaiton = getIntent().getExtras().get("your_data_key").toString();
//做你想做的事....
}
通常这是我们在通知中从服务器获得的结构
{
"notification": {
"body": "Cool offers. Get them before expiring!",
"title": "Flat 80% discount",
"icon": "appicon",
"click_action": "activity name" //optional if required.....
},
"data": {
"product_id": 11,
"product_details": "details.....",
"other_info": "......."
}
}
这是由你决定的,你想给数据键或者你想给任何你可以给.......的通知
无论你在这里给出什么,用相同的键,你都会得到数据.........
有少数情况下,如果你没有发送点击动作在这种情况下,当你将点击通知默认活动将打开,但如果你想打开你的特定活动时,应用程序是在后台,你可以从这个handleIntent方法调用你的活动,因为这是每次调用
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");
}
此情况仅用于firebase管理通知
如果应用程序在后台,则不会触发FirebaseMessagingService
要处理这种情况,请转到launcher activity,检查附加的intent bundle,并使用以下代码打印出所有数据:
intent?.extras?.let {it->
for (key in bundle.keySet()) {
val value = bundle[key]
Log.d("NotificationData", String.format("%s %s (%s)", key, value.toString(), value!!.javaClass.name))
}
}
显示所有数据类型的签入日志;
例子:
我想从通知中获得周和标题将使用这段代码
intent?.extras?.let {it->
if (it.containsKey("week")){
}
if (it.containsKey("title")){
}
