[firebase_messaging] set notification channel id (notification in background Not working) #88

MahmoodBakhshayesh · 2019-09-04T07:01:15Z

Describe the bug
the function onResume and onLunch not working on android platform, while they work fine on IOS,
i receive the following message on console instead of printed strings in those functions:

"W/FirebaseMessaging(24847): Missing Default Notification Channel metadata in AndroidManifest. Default value will be used."

onMessage function works fine, the problem is when the app is in background

To Reproduce
try to print something in onResume and onLunch functions

Expected behavior
the functions be called on work fine as they do on IOS

Additional context
my guess is that it has something to do with android notification channel id which should be added in android manifest

when i add that to manifest the message change to :
"Notification Channel set in AndroidManifest.xml has not been created by the app. Default value will be used."

The text was updated successfully, but these errors were encountered:

@MahmoodBakhshayesh Thanks for flagging this, looks like we don't currently have support for message channels. We should add this.

Feel free to submit a PR if you have a solution.

Any clear documents to setup firebase messaging?
I follow 5.1.6 instruction. Facing the above issue

Did someone find a workaround for this issue? Thanks

bhanuka96 · 2020-08-07T04:27:22Z

@NoeLopez are you sure? is it only support for topic? okay, but how group notification works on like whatsapp/gmail?
I think you talk about the device group.

NoeLopez · 2020-08-07T04:30:09Z

@bhanuka96 Do you mean that notifications are grouped when they arrive?

deep01code · 2020-08-07T04:34:02Z

@NoeLopez I still get this error :(
W/FirebaseMessaging( 6367): Notification Channel set in AndroidManifest.xml has not been created by the app. Default value will be used.

bhanuka96 · 2020-08-07T04:34:12Z

@bhanuka96 Do you mean that notifications are grouped when they arrive?

yes like this https://developer.android.com/training/notify-user/group . if "A" user sent multiple messages to the "B" user. currently, there are lots of notifications came to in my notification panel, I want to group notification for that. (it's mean like above image like gmail/whatsapp). if "C" user sent multiple message to the "B user". I want to 2 groups

NoeLopez · 2020-08-07T04:38:31Z

@bhanuka96 Those types of implementations would have to be done with Local Notification

NoeLopez · 2020-08-07T04:40:12Z

@deep01code It would be nice to be able to see your code to see where it goes wrong, remember to add it in Java class and in Android Manifest

bhanuka96 · 2020-08-07T04:45:57Z

@bhanuka96 Those types of implementations would have to be done with Local Notification

I tried, not working on foreground or background... I saw this react native answer about same issue. I think this part of the firebase_messaging plugin right? invertase/react-native-firebase#449 (comment)

NoeLopez · 2020-08-07T04:49:29Z

@bhanuka96 Apparently it seems like if it's a Firebase issue I'm really sorry I can't help you

braysonjohn148 · 2020-08-07T05:38:12Z

I followed exactly the tutorials on youtube on how to setup these notification, they don't do these staffs but they get notifications when the app is teriminated. I don't know what wrong with my code.

firebase_messaging: ^6.0.16

_backgroundMessageHandler i even tried calling FlutterLocalNotificationsPlugin, still don't show notifications when the app is terminated.

`

        <meta-data android:name="com.google.firebase.messaging.default_notification_channel_id" android:value="@string/default_notification_channel_id"/>`

NoeLopez · 2020-08-07T06:09:31Z

@braysonjohn148 If want to be notified in your app (via onResume and onLaunch, see below) when the user clicks on a notification in the system tray include the following intent-filter within the <activity> tag of your android/app/src/main/AndroidManifest.xml:

<intent-filter>
     <action android:name="FLUTTER_NOTIFICATION_CLICK" />
     <category android:name="android.intent.category.DEFAULT" />
 </intent-filter>

Optionally handle background messages

Background message handling is intended to be performed quickly. Do not perform long running tasks as they may not be allowed to finish by the Android system

By default background messaging is not enabled. To handle messages in the background:

Add the com.google.firebase:firebase-messaging dependency in your app-level build.gradle file that is typically located at <app-name>/android/app/build.gradle.

dependencies {
  // ...

  implementation 'com.google.firebase:firebase-messaging:20.2.4'
}

you can find out what the latest version of the plugin is here

Add an Application.java class to your app in the same directory as your MainActivity.java. This is typically found in <app-name>/android/app/src/main/java/<app-organization-path>/.

package com.domain.myapplication;

import io.flutter.app.FlutterApplication;
import io.flutter.plugin.common.PluginRegistry;
import io.flutter.plugin.common.PluginRegistry.PluginRegistrantCallback;
import io.flutter.plugins.GeneratedPluginRegistrant;
import io.flutter.plugins.firebasemessaging.FlutterFirebaseMessagingService;

public class Application extends FlutterApplication implements PluginRegistrantCallback {
  @Override
  public void onCreate() {
    super.onCreate();
    FlutterFirebaseMessagingService.setPluginRegistrant(this);
  }

  @Override
  public void registerWith(PluginRegistry registry) {
 FirebaseMessagingPlugin.registerWith(registry.registrarFor("io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin"));
  }
}

In Application.java, make sure to change package com.domain.myapplication; to your package's identifier. Your package's identifier should be something like com.domain.myapplication for your application package
Set name property of application in AndroidManifest.xml. This is typically found in <app-name>/android/app/src/main/.

<application android:name=".Application" ...>

and the json that sends from Postman or from firebase in the data part has to go this, very important

"click_action": "FLUTTER_NOTIFICATION_CLICK"

Aquí hay un ejemplo del cuerpo de un JSON que debe enviarse desde Postman

{
  "notification": {
    "body": "here you put the body of the message",
    "title": "here you put some title"
  },
  "priority": "high",
  "data": {
    "click_action": "FLUTTER_NOTIFICATION_CLICK",
    "other_data": "any message",
    .....
  },
  "to": "your token ......"
}

Hope this answer can help you solve your problem. Regards

braysonjohn148 · 2020-08-07T06:31:19Z

what i want is when an app is completely terminated. Meaning the phone is either in the pocket or user on other apps. When a new notification arrives the user to get a push notification even when the app is terminated. Currently when i close the app and send the notification. I cannot see the notification in the system tray. I even tried using the firebase console FCM to fire test messages on my app

NoeLopez · 2020-08-07T06:37:25Z

@braysonjohn148 that is done in the onLaunch method (it is when the app has closed completely) and onResume is when the app is in the background, you just have to implement there the actions you want it to do

Where is default_notification_channel_id?
It is FLUTTER. Why don't you describe about it?

android/app/src/main/res/values/strings.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="default_notification_channel_id" translatable="false">fcm_default_channel</string>
</resources>

same issue is facing from me also

danilomna · 2020-09-01T18:03:48Z

Yes of course,

In the Application file that flutter recommends you add a globar variable that will be the name of your id channel, for example

public static final String CHANNEL_HIGH = "channel1";

where channel1 is the id channel, then you create a method like the following
private void createNotificationChannels() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel channelHigh = new NotificationChannel(
                    CHANNEL_HIGH,
                    "Notificación Importante",
                    NotificationManager.IMPORTANCE_HIGH
            );

            channelHigh.setDescription("Canal Alto");

            NotificationManager manager = getSystemService(NotificationManager.class);
            manager.createNotificationChannel(channelHigh);

        }
    }
where Notificacion Importante is the name that will appear in the notification settings on the cell phone, then add I'm in the AndroidManifest
<application
        android:name=".Application"
        android:icon="@mipmap/ic_launcher"
        android:label="NotificacionPush">

        <activity
            android:name=".MainActivity" ...
           .......


   <meta-data
            android:name="com.google.firebase.messaging.default_notification_channel_id"
            android:value="channel1"/>

</application>
Note that in android:value it must be the name of the channel ID, which you created in your public variable in the application class.

and with that the notifications will come out with bubble

Hi @NoeLopez , does this solve the onBackgroundMessage callback issue? Could you help with a full project example on github?

danilomna · 2020-09-01T18:05:14Z

still happen! onBackgroundMessage still not working

hi @Gperez88 have you found a fix for this issue? It is not working for me too.

danilomna · 2020-09-01T18:08:51Z

Does anybody found a workaround or fix to make onBackgroundMessage work?

danilomna · 2020-09-02T01:29:36Z

@NoeLopez I still get this error :(

@yourshinsuke @danilomna

In order to get ride of this, you need to create android notification channel to your app.

Go to this link for more details -- https://developer.android.com/training/notify-user/channels

I have uploaded to Github repository -- https://github.com/Stone2517/Truact-1

AndroidManifest.xml

<application>
      <activity>
           .........
      </activity>
      <meta-data 
            android:name="com.google.firebase.messaging.default_notification_channel_id"
            android:value="@string/default_notification_channel_id"/>  ----- Add this.
 </application>

Application.java

public class Application extends FlutterApplication implements PluginRegistrantCallback {
    @Override
    public void onCreate() {
        super.onCreate();
        this.createChannel();   ----- Add this.
        FlutterFirebaseMessagingService.setPluginRegistrant(this);
    }

    @Override
    public void registerWith(PluginRegistry registry) {
        io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin.registerWith(registry.registrarFor("io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin"));
        PathProviderPlugin.registerWith(registry.registrarFor("io.flutter.plugins.pathprovider.PathProviderPlugin"));
    }
    private void createChannel(){   ----- Add this.
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            // Create the NotificationChannel
            String name = getString(R.string.default_notification_channel_id);
            NotificationChannel channel = new NotificationChannel(name, "default", NotificationManager.IMPORTANCE_HIGH);
            NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
            notificationManager.createNotificationChannel(channel);
        }
    }
}

strings.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="default_notification_channel_id">default_notification_channel_id</string>  ----- Add this.
</resources>

Hey all 👋

As part of our roadmap (#2582) we've just shipped a complete rework of the firebase_messaging plugin that aims to solve this and many other issues.

If you can, please try out the dev release (see the migration guide for upgrading and for changes) and if you have any feedback then join in the discussion here.

Given the scope of the rework I'm going to go ahead and close this issue in favor of trying out the latest plugin.

Thanks everyone 🤓
