I'm following this guide to configure my NotificationChannels https://developer.android.com/training/notify-user/channels.html#java
But when I open the settings screen with this code:
Intent intent = new Intent(Settings.ACTION_CHANNEL_NOTIFICATION_SETTINGS);
intent.putExtra(Settings.EXTRA_APP_PACKAGE, getPackageName());
intent.putExtra(Settings.EXTRA_CHANNEL_ID, myNotificationChannel.getId());
startActivity(intent);
There is no tune preference. I can only turn On/Off the sound. Do I need some additional configuration of my channel, or is it impossible to set custom tune of notification?(I know that I can play the tune manually when notification pops up, but I really don't like this solution)
Channel code:
public String createChannel() {
NotificationChannel channel = new NotificationChannel(INCOMING_CHAT_CHANNEL_ID, INCOMING_CHAT_CHANNEL_TITLE,
NotificationManager.IMPORTANCE_HIGH);
channel.setDescription(INCOMING_CHAT_CHANNEL_DESCRIPTION);
getNotificationManager().createNotificationChannel(channel);
return channel.getId();
}
And then I use returned channel Id:
Notification sound setting will only appear for higher priority notifications.
Try to change your Channel behaviour to first (Make sound and pop up screen) or second (Make sound) option.
Please try to post the code where you are creating the Notification channel.
I am using react native firebase library for push notification and i am playing two different sound for two different notification so i am playing some .mp3 sound for one notification and default for other one so problem is app is playing only that sound which is coming in first notification for app and for rest notification playing the first played sound so I think the issue is notification information is not updating that's what it is playing the same sound for all the notification which app got for first notification.even we are getting right information in notification data but it is not updating the sound.
Version:
react-native-firebase:"4.3.8"
react-native:"0.56.1"
yes I am getting data from firebase and below is my code to set Sound for notification.
this.notificationListener = firebase
.notifications()
.onNotification((notification: Notification) => {
const channel = new firebase.notifications.Android.Channel(
'test-channel',
'Test Channel',
firebase.notifications.Android.Importance.Max
).setDescription('My apps test channel');
if (notification && notification.data) {
const data = notification.data;
if (data && data.messageKey) {
//here I set the sound on basis of notification data to the channel
...
}
}
// Create the channel
firebase.notifications().android.createChannel(channel);
// Process your notification as required
notification
.android.setChannelId('test-channel')
.android.setSmallIcon(Images.logoSmall);
firebase.notifications()
.displayNotification(notification);
});
1) In android, add your custom sound file to [project_root]/android/app/src/main/res/raw
2) Create notification channel
const channel = new firebase.notifications.Android.Channel('channel_name', 'channel_name', firebase.notifications.Android.Importance.High)
.setDescription('channel_name')
3) Add sound into notification .setSound('default')
firebase.notifications().android.createChannel(channel);
const localNotification = new firebase.notifications.Notification({
sound: 'default',
show_in_foreground: true,
})
.setNotificationId(new Date().valueOf().toString())
.setTitle(noti_payload.title)
.setSound('default')
.setBody(noti_payload.message)
.setData({
now: new Date().toISOString(),
payload: noti_payload,
})
.android.setAutoCancel(true)
.android.setBigText(noti_payload.message)
.android.setLargeIcon('ic_launchers')
.android.setVibrate(1000)
.android.setColor('#74c900')
.android.setColorized(true)
.android.setChannelId('channel_name') // e.g. the id you chose above
.android.setSmallIcon('ic_launchers') // create this icon in Android Studio
.android.setPriority(firebase.notifications.Android.Priority.High);
firebase
.notifications()
.displayNotification(localNotification)
Important Note:-
After doing above step please uninstall app and delete bundles, because some time cached bundle asset contain default sound and changes are not reflected.
every time you change sound you need to build bundle again
Please check following link also
https://rnfirebase.io/docs/v4.0.x/notifications/reference/Notification
setSound() was deprecated in API 26. Use NotificationChannel.setSound() instead.
I'm trying to implement Local notifications(with click events and HeadUP Notifications) for my android application using Xamarin.Forms. I've followed Microsoft documentation for Local Notifications but I don't know how to implement this.Can anyone please share any working sample for this.
Thank You.
From Android official document ,there are two ways to set importance level.
First Solution: (Not Work)
If a notification's priority is flagged as High, Max, or full-screen, it gets a heads-up notification.
Examples of conditions that may trigger heads-up notifications include:
The notification has high priority and uses ringtones or vibrations.Using physical device to have a try as follow:
builder.SetVibrate(new long[0]);
builder.SetPriority((int)NotificationPriority.High);
Here is a similar discussion about Heads-up notification.
Unfortunately, the above solution does not work.
Second Solution:(Work)
The correct way in Xamarin Android can set property of Channel .If channel created by NotificationImportance.High,then can show heads-up.You can refer to this official sample.And Modify your CreateNotificationChannel method as follow:
void CreateNotificationChannel()
{
if (Build.VERSION.SdkInt < BuildVersionCodes.O)
{
// Notification channels are new in API 26 (and not a part of the
// support library). There is no need to create a notification
// channel on older versions of Android.
return;
}
var name = Resources.GetString(Resource.String.channel_name);
var description = GetString(Resource.String.channel_description);
//Replace follow NotificationImportance.Default to NotificationImportance.High
var channel = new NotificationChannel(CHANNEL_ID, name, NotificationImportance.High)
{
Description = description
};
var notificationManager = (NotificationManager) GetSystemService(NotificationService);
notificationManager.CreateNotificationChannel(channel);
}
I have preset order of notification channels, that can be change. How to change order of notification channels? I try to sort by channel_id and channel_name, but it is not work.
There was error in my solution. I try to add number of channel on start of channel id for sorting. So i had this:
56_server_channel_id
78_server_channel_id
155_server_channel_id
9998_default_app_channel_id
9999_default_app_channel_id
But because of missing leading zeros, it sorted not as i expected. So, right solution is:
0056_server_channel_id
0078_server_channel_id
0155_server_channel_id
9998_default_app_channel_id
9999_default_app_channel_id
I'm building an application using Ionic Framework that implements a chat function similar to good-old facebook messenger, in that i want to notify users of a chat message, but if they view it elsewhere, i want to remove the notification from their home screen.
I'm using firebase as a back-end for push notifications (though that could be changed i suppose).
I know that you can't expire a remote notification, but i've been told you can expire + remove a local notification, so my question is - can i reliably receive a remote notification, create a local one, and display that, and then in response to a notification with a scope of 'expire' or 'remove', delete a local notification so that my users don't see a duplication of information?
Most plugins tend to detect the status of the app and add a remote notification to the homescreen with the info you've pushed by default, is there a way to avoid this?
Thanks guys.
EDIT:
- Local notifications: http://ionicframework.com/docs/native/local-notifications/
- Firebase cloud messaging: https://github.com/fechanique/cordova-plugin-fcm
As far as I can tell there're no plugins which accomplish all what you need. However..
can i reliably receive a remote notification, create a local one, and display that, and then in response to a notification with a scope of 'expire' or 'remove', delete a local notification so that my users don't see a duplication of information?

Yes, by using silent notifications and building the local notification by yourself.
For a project I'm working in, I modified the plugin cordova-plugin-fcm to add support for (local on demand) notifications dismiss/display, send multiple notifications to the cordova app, and some PRs that are not included yet. Also I build the notification by myself, to have full control of what is displayed. You can take a look at the code to get some ideas.
In brief it works like this:
Firstly, I send a "silent" push to the app, which is not displayed by Android:
{
"content_available": true, // IMPORTANT: For Apple -> content-available: 1, for firebase -> content_available: true
"priority": "high",
"to": "/topics/all", // or to a fcm token
"data"{
"title": "My title", // this implies that you display the notification by yourself
"body": "My body", // this implies that you display the notification by yourself
"type": "NEW_USER_MESSAGE", // only relevant to this project
"userId": "1", // only relevant to this project
"timestamp", "150000000"
}
}
Note: If the payload have the "notification": {} item, Android will display it on the system tray (if the app is in background).
https://firebase.google.com/docs/cloud-messaging/concept-options#notifications_and_data_messages
Secondly, when the push arrives to the app (in onMessageReceived()), I build the local notification, assigning it a TAG and an ID. This is the way you can use to dismiss it later.
For example, you could create a local notification with the TAG "NEW_USER_MESSAGE" and ID 1 (a constant indicating a state of the message, or the user ID for example). Also, Android will replace notifications with the same TAG and ID, so this is another way to automatically replace notifications (for example if you send a generic message, like "New update available").
public static String TYPE_NEW_USER_MESSAGE = "NEW_USER_MESSAGE";
public static String TYPE_USER_LEFT_ROOM = "USER_LEFT_ROOM";
NotificationManager notificationManager =
(NotificationManager) _ctx.getSystemService(Context.NOTIFICATION_SERVICE);
// based in the type of the message you've received, you can stylize the notification
if (type.equals( TYPE_USER_LEFT_ROOM )){
notificationBuilder.setColor(Color.RED);
notificationBuilder.setLights(Color.RED, 1000, 500);
}
else if (type.equals( TYPE_NEW_USER_MESSAGE )){
notificationBuilder.setColor(Color.BLUE);
notificationBuilder.setLights(Color.BLUE, 1000, 1000);
}
Notification n = notificationBuilder.build();
notificationManager.notify(type, userId, n);
One advantage of doing it in this way, is that you have full control of the notification to be displayed, so you can stylize it like you want.
If you want to discard expired messages, you can check out the elapsed time between the sent timestamp and the current timestamp:
java.util.Date now = new java.util.Date();
java.util.Date sent_timestamp = new java.util.Date( Long.valueOf(timestamp.toString()) );
final Long elapsed_time = ((now.getTime() - sent_timestamp.getTime()) / 1000);
Log.d(TAG, "New message. sent " + elapsed_time + "s ago");
Thirdly, when the user clicks on a notification Android will launch your app, and the plugin will send the payload of the push message to the cordova view (onNotificationReceived()).
Once your app is opened and you have received the push message, you can dismiss it adding a new action to the plugin:
onNotificationReceived(data){
if (data.wasTapped === true){
if (data.type === 'NEW_USER_MESSAGE'){
FCMPlugin.dismissNotification(NEW_USER_MESSAGE, 1);
}
}
}
The Android action:
else if (action.equals( ACTION_DISMISS_NOTIFICATION )) {
cordova.getThreadPool().execute(new Runnable() {
public void run() {
try{
Log.d(TAG, "FCMPlugin dismissNotificaton: " + args.getString(0)); //tag
NotificationManager nManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
nManager.cancel(args.getString(0)/*NEW_USER_MESSAGE*/, args.getInt(1) /*1*/);
Log.d(TAG, "FCMPlugin dismissNotificaton() to remove: " + id); //tag
callbackContext.success();
}catch(Exception e){
callbackContext.error(e.getMessage());
}
}
});
https://github.com/TrustedCircles/cordova-plugin-fcm/blob/master/src/android/FCMPlugin.java#L286
And the method exposed to the cordova app:
// dismisses a notification by tag+id
FCMPlugin.prototype.dismissNotification = function( tag, userId, success, error ){
exec(success, error, "FCMPlugin", 'dismissNotification', [tag, userId]);
}
https://github.com/TrustedCircles/cordova-plugin-fcm/blob/master/www/FCMPlugin.js#L65
The only tricky bit with notifications in cordova/ionic is the JS part receiving the notification and triggering the Android code.
I used https://github.com/phonegap/phonegap-plugin-push library and its pretty straight forward.
There is a callback when notifications are received in JS(Cordova/Ionic), use this to render you notifications locally in Android.
P.S: Basel's answer tells you how to clear your notifications, so I decided to leave that bit out.
