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]
像这样简单的总结
如果你的应用正在运行;
onMessageReceived ()
是触发器。
如果你的应用程序没有运行(通过滑动杀死);
onMessageReceived ()
不是直接触发和传递的。如果你有特殊的键值对。它们不工作，因为onmessagerecreceived()不工作。
我找到了这条路;
在你的启动器活动中，放入这样的逻辑，
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState, R.layout.activity_splash);
if (getIntent().getExtras() != null && getIntent().getExtras().containsKey("PACKAGE_NAME")) {
// do what you want
// and this for killing app if we dont want to start
android.os.Process.killProcess(android.os.Process.myPid());
} else {
//continue to app
}
}
在这个if块中，根据firebase UI搜索你的密钥。
在这个例子中，我的键和值就像上面那样;(对不起，语言=))
当我的代码工作时，我得到“com.rda.note”。
android.os.Process.killProcess(android.os.Process.myPid());
有了这行代码，我关闭了我的应用程序，打开谷歌播放市场
快乐编码=)
从服务器请求中完全删除通知有效负载。只发送数据并在onmessagerreceived()中处理它，否则当应用程序在后台或被杀死时，你的onmessagerreceived将不会被触发。
这是我从服务器发送的:
{
"data":{
"id": 1,
"missedRequests": 5
"addAnyDataHere": 123
},
"to": "fhiT7evmZk8:APA91bFJq7Tkly4BtLRXdYvqHno2vHCRkzpJT8QZy0TlIGs......"
}
你可以像这样在onMessageReceived(RemoteMessage message)中接收你的数据(假设我需要获取id)
Object obj = message.getData().get("id");
if (obj != null) {
int id = Integer.valueOf(obj.toString());
}
类似地，你可以在onmessagerecreceived()内从服务器获得任何数据。
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\"}}"
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")){
}
