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]
感谢你们所有人的回答。但是我通过发送数据消息而不是发送通知来解决这个问题。

并在onmessagerreceived中捕获数据
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "MyFirebaseMsgService";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d(TAG, "From: " + remoteMessage.getFrom());
// Check if message contains a data payload.
if (remoteMessage.getData().size() > 0) {
Log.d(TAG, "Message data payload: " + remoteMessage.getData());
sendNotification(remoteMessage.getData().get("message"));
}
// Check if message contains a notification payload.
else if (remoteMessage.getNotification() != null) {
Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
sendNotification(remoteMessage.getNotification().getBody());
}
}
private void sendNotification(String messageBody) {
Intent intent = new Intent(this, Notify.class).putExtra("msg",messageBody);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
String channelId = "idddd";
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(MyFirebaseMessagingService.this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("FCM Message")
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}
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")){
}
根据firebase文档在发送下游使用firebase，有两种类型的有效载荷:
数据
此参数指定消息有效负载的自定义键-值对。
客户端应用程序负责处理数据消息。数据消息只有自定义键值对。
通知
此参数指定通知有效负载的预定义的、用户可见的键-值对。FCM自动代表客户端应用程序将消息显示给最终用户设备。通知消息具有一组预定义的用户可见键。
当你在前台时，你可以使用onmessagerecreceived()在FCM内部获取数据，你可以从数据有效载荷中获取数据。
data = remoteMessage.getData();
String customData = (String) data.get("customData");
当您在后台时，FCM将根据通知有效载荷的信息在系统托盘中显示通知。系统托盘上用于通知的标题、消息和图标都来自通知有效负载。
{
"notification": {
"title" : "title",
"body" : "body text",
"icon" : "ic_notification",
"click_action" : "OPEN_ACTIVITY_1"
}
}
当你想在应用程序处于后台时自动在系统托盘上显示通知时，使用这个通知有效载荷。
当你的应用程序在后台运行时，为了获得通知数据，你应该在通知有效载荷中添加click_action。
如果你想打开你的应用并执行一个特定的动作(在后台)，在通知有效载荷中设置click_action，并将其映射到你想要启动的Activity中的意图过滤器。例如，将click_action设置为OPEN_ACTIVITY_1来触发一个意图过滤器，如下所示:
<intent-filter>
<action android:name="OPEN_ACTIVITY_1" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
把intent-filter放在你的清单上，在你的一个activity标签里面。当你点击通知时，它将打开应用程序并直接进入你在click_action中定义的活动，在本例中为“OPEN_ACTIVTY_1”。
在这个活动中，你可以通过以下方式获取数据:
Bundle b = getIntent().getExtras();
String someData = b.getString("someData");
我使用FCM为我的android应用程序和使用两个有效载荷。
下面是我使用的JSON示例:
{
"to": "FCM registration ID",
"notification": {
"title" : "title",
"body" : "body text",
"icon" : "ic_notification",
"click_action" : "OPEN_ACTIVITY_1"
},
"data": {
"someData" : "This is some data",
"someData2" : "etc"
}
}

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");
}
