Open a web browser from push notification without launching the application? - android

My application is running in the background and I send a push notification through postman using the payload below.
Now when I send this, I get the notification and when I tap it, it launches my application's Main Activity. But I want to launch the web browser which opens the link that I send in the notification body. How to do this?? Can somebody please help.
{
"to" : "MY_TOKEN",
"collapse_key" : "type_a",
"notification" : {
"body" : "https://developer.android.com/training/notify-user/build-notification#click",
"title": "Title of Your Notification in Title",
"key_1" : "Value for key_1",
"key_2" : "Value for key_2",
"click_action" : "OPEN_WEB"
}

FirebasePushNotificationPlugin(xamarin) - events not fire when app in background(android)

I use this plugin for my Xamarin Forms app(android).
Any event not fire when app is in background. Events work when the application is in the foreground. But app is background any event not fire, the app is just opening. But I need to pass the message parameters to the application. I'm not sure if this is a bug, maybe this is my mistake. I will be grateful for any help.
I use this api for send message:
https://fcm.googleapis.com/fcm/send
This is my payload:
{
"data": {
"id_serv" : "12",
"id_group" : "1",
"click_action":"Accept"
},
"notification" : {
"body" : "test",
"title" : "test"
},
"priority": "high",
"condition": "'g1' in topics"
}
I also subscribe to all available events - OnNotificationAction, OnNotificationOpened, OnNotificationReceived.
I also try to subscribe at the android level, but this also does not work. Any help?
When the app is in the background firebase use their notification system that way your code not called.
If you want that your code will be called you need to pass the data through the data object only and not use the notification object.
so your notification object need to be like that:
"data": {
"id_serv" : "12",
"id_group" : "1",
"click_action":"Accept",
"body" : "test",
"title" : "test"
},
"priority": "high",
"condition": "'g1' in topics"
}

i don't know anything about xamarin, but in firebase version above 16, you just got push notification data when app is running,
when app is killed: after click on notification, android open your first activity with bundle (extra data), and you must get this data and use them, so debug your app and check your first activity bundle after clicking on notification

Fcm Notification cannot show image if app close

I am sending notification and handle notification FirebaseMessagingService.
But if app on background FirebaseMessagingService cannot handle notification and not show image.
How can I do this? (If the application is in the foreground, the picture is shown in the notification.)
And if I use onesignal image showing all times.
{
"to" :"4sQrChOF16uMYYEKeiRz6dzCnN3m9OCE9jwOyPBOD92IlzljWvQ_1quiYyluP",
"notification" : {
"body" : "great match!",
"title" : "Portugal vs. Denmark",
"icon" : "myicon"
},
"data": {
"body" : "great match!",
"title" : "Portugal vs. Denmark2222",
"img_url" : "https://encrypted-tbn0.gstatic.com/images?q=tbn%3AANd9GcRYJ_0NZFg0htNXwmKkyTv76bw05EacXaXNnqd4ZrPB7wVTXNxR"
}
}
Here are 2 ways you can show an image in your notification consistently:
[Recommended approach] - Using the newer HTTP V1 API of FCM:
Here you can give an image URL as part of the notification payload and firebase will handle downloading and displaying the image for you. Here's the documentation link for the same.
Using the older legacy API of FCM:
Send a data-only payload(Don't send the notification object at all). Include image URL as part of the data payload. This will give you control in the onMessageReceived method(in both foreground and background cases). Here you can generate and display the notification however you like it. Retrieve the image URL here and download the image and create a notification with the image or however you want it to be rendered.

Handle FCM notification In Android Oreo when the App is closed or pause State

Here I facing Notification issue in Android Oreo, That is when the FCM sent push notification to the Android Oreo, it will show the notification when the app is run in the foreground ,that is because of the service is running in the background , it can handle additional parameters and its value , but the problem arise when the app is close or paused state , The OS destroy the Service automatically when the app is closed or paused states , in order the handle notification FCM provides High priority Push notification method ,in which the push notification Json has two parts ,one is "data" , and another one is "notification", The data part can handle by the services when the app is running in foreground , but the Notification part manage by Android OS , There are default keys to handle notification for display notification icons ,title,messaged and Priority , With the use of high priority push notification can wake up the app when we hit on the notification ,and access the information by applying bundle with the starting Activity . but the problem is how to put extra data in In notification , when I trying to add additional data in to the "notification" part into the Json ,The OS not displaying notification . So how can I manage this issue .. ?
{
"to" : "e1w6hEbZn-8:APA91bEUIb2JewYCIiApsMu5JfI5Ak...",
"notification": {
"body": "message",
"title": "Title",
"icon": "appicon"
},
"data" : {
"body": "message",
"title": "Title",
}}
Try to add an extra parameter in notification object from server side manually. It worked for me.
{ "to" : "e1w6hEbZn-8:APA91bEUIb2JewYCIiApsMu5JfI5Ak...",
"notification": {
"body": "message",
"title": "Title",
"icon": "appicon" ,
"extra_param":"value"
},
"data" : {
"body": "message",
"title": "Title",
}
}

Not getting FCM notification when app is completely killed

I have been trying to send the Push notification using FCM. It works completely when the app is in Foreground or background. But if i kill the app from recent list then i'm not getting any notification.
This is my structure of FCM with data payload
{"registration_ids":["here is my FCM token"],
"data":{
"body" :"Hello All, Hope you had a great time!",
"title":"Title",
"click_action":"ACTIVITY_MESSAGE",
"sound":"default",
"type" : "message",
"message": "message_here",
"time" : "2016-12-14 03:37:pm"
}
}
This is the structure with data and notification
{"registration_ids":["Here is my FCM token"],
"notification":{
"body" : "Hello All, Hope you had a great time!",
"title":"title here",
"click_action":"ACTIVITY_HOME",
"sound":"default"
},
"data":{
"type" : "message",
"message": "message_here",
"time" : "2016-12-14 03:37:pm"
}
}
I have also tried the same with notification tag and data as well but nothing is working in case whent the app is killed. If any one have any idea how can i get the notification in case of my app is killed then do share.
You should try to put "forceStart": "1" inside the data brackets.
In this way you should force the application to start the notification.

Retrieve notification values from a notification in system tray android firebase FCM

I am using firebase to send notifications to my app. I want to save the notifications received on each device in a local database. The problem is, when the app is in the background and a notification is received, the method onMessageReceived() won't be called, but instead the notification would be added to the system tray as per documentation. The documentation also mentions the following for receiving a notification when the app is in background:
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.
So, when I'm trying to access the extras in the intent, the keys of the notification are not found.
My code in MainActivity.java:
if (getIntent().getExtras() != null) {
for (String key : getIntent().getExtras().keySet()) {
Object value = getIntent().getExtras().get(key);
Toast.makeText(this, "Key: " + key + " Value: " + value, Toast.LENGTH_LONG).show();
}
}
The notification we are sending from the server:
{
"to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
"notification" : {
"body" : "great match!",
"title" : "Portugal vs. Denmark",
"icon" : "myicon"
}
}
Anyone has an idea of how I can retrieve the values inside the notification?
This is the intended behavior (as you've seen in the documentation). If you're using a notification-only message payload (which you are), onMessageReceived() will only be called if your app is in foreground, if not, the System Tray will be receiving it.
The data being referred to in (emphasis mine):
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.
is the data message payload (See Message Types).
You'll have to send a payload with both notification and data. Like so:
{
"to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
"notification" : {
"body" : "great match!",
"title" : "Portugal vs. Denmark",
"icon" : "myicon"
},
"data": {
"body" : "great match!",
"title" : "Portugal vs. Denmark",
"icon" : "myicon"
}
}
Also see my answer here.
All you have to do is update your notification push format.
From:
{
"to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
"notification" : {
"body" : "great match!",
"title" : "Portugal vs. Denmark",
"icon" : "myicon"
}
}
To
{
"to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
"data" : {
"body" : "great match!",
"title" : "Portugal vs. Denmark",
"icon" : "myicon"
}
}
Explanation:
There is a firebase service running by your system which works for all app and handle all push notification if it contains the "notification" tag. but if contain the "data" tag only it just handover the task to the service created by the app where you can do anything.In your case show user notification and save it to the local db. For more you read here Documentation : Handle Messages.
It's not a simple or clean solution, but you could use a NotificationListenerService to receive a callback for each notification. A further limitation is that it supports only API 18 and above.
Add this to manifest file
<intent-filter>
<action android:name=".MainActivity" />
<category android:name="android.intent.category.DEFAULT" />
