Android HandleNotificationOpened Or HandleNotificationReceived

[ketanparekh]

Looked both #49 #86

I am working with Xamarin.Forms Onesignal SDK and I am able to get Push Notification in iOS and Android both. I want to get additional data when android application is not running and user open push notification.

Scenarion :

• Android application is not running or in background.
• Click on received notification.
• HandleNotificationOpened Or HandleNotificationReceived is not called.
• we want additional Data Key/Value on start of the application which is shared in push notification.

Version Information :

• Xamarin.Forms 3.1.0.637273
• VS 7.5.3 (build 7)
• OneSignal 3.2.0
• Android API 25/27

Thanks, Ketan

@ketanparekh HandleNotificationOpened should be called in this case. Can you share your OneSignal code?

[ketanparekh]

@jkasten2 Thanks for the reply. Below is the code for 'OneSignal'.

Initial in public App()

OneSignal.Current.StartInit("xxxxxx")
                     .HandleNotificationReceived(HandleNotificationReceived)
                     .HandleNotificationOpened(HandleNotificationOpened)
                     .EndInit();

 private static void HandleNotificationReceived(OSNotification notification)
{
            OSNotificationPayload payload = notification.payload;
            string message = payload.body;
            Dictionary<string, object> additionalData = payload.additionalData; 

            if (additionalData != null)
            {
                if (additionalData.ContainsKey("screenName"))
                {
                    pushScreenName = Convert.ToString(additionalData["screenName"]);
                }
                else
                {
                    pushScreenName = "";
                }
            }
}

private static void HandleNotificationOpened(OSNotificationOpenedResult result)
{
            OSNotificationPayload payload = result.notification.payload;
            Dictionary<string, object> additionalData = payload.additionalData;
            string message = payload.body;
            string actionID = result.action.actionID;

            if (additionalData != null)
            {
                if (additionalData.ContainsKey("screenName"))
                {
                    pushScreenName = Convert.ToString(additionalData["screenName"]);
                }
                else
                {
                    pushScreenName = "";
                }
            }
}

HI all, I am experiencing similar behaviour on Android.

Scenario : 1) Android application is not running.

• Click on received notification.
• Application is starting and opening default main page
• HandleNotificationOpened IS NOT triggered. We are using additional Key/Value data to perform action in the app - go to different screen.

2) Android application is running in background.

• Click on received notification.
• Application is starting.
• HandleNotificationOpened IS triggered. We are using additional Key/Value data to perform action in the app - go to different screen and this is executed correctly.

Details: Xamarin.Forms 3.1.0.697729 VS mac 7.5.4 (build 3) OneSignal 3.2.0 Min Android Version: API level 21 Target Android Version: API level 26 Target Framework: 8.1

Actual device is Android 7.0 device

here is the code `private async static void HandleNotificationOpened(OSNotificationOpenedResult result) { OSNotificationPayload payload = result.notification.payload; string message = payload.body;

        MessageItem newMessage = new MessageItem();
        newMessage.Subject = payload.title;
        newMessage.Body = payload.body;
        newMessage.TimeSent = DateTime.Now;
        await App.Database.SaveItemAsync(newMessage);

        if(payload.additionalData.Count > 0)
        {

            //check to see what we need to do
            Dictionary<string, object> toDo = payload.additionalData;

            Object screenVal;
            toDo.TryGetValue("OpenScreen", out screenVal);

            String strScreen = screenVal.ToString();

            // find which screen id we need to use
            Helper clsHelper = new Helper();
            ScreenDef gotoScreen = clsHelper.GetScreenID(GlobalVars.XMLScreens, strScreen);
            if (gotoScreen.ScreenID != -1)
            {
                if (gotoScreen.ScreenType == "item_description")

                    await App.Current.MainPage.Navigation.PushModalAsync(new pageDetails(gotoScreen.ScreenID));    
            }
            //}

        }
    }`

On iOS the same code is working without any issues. Also in Android Emulator (API 24) behaviour is the same.

I have the same issue here... On method HandleNotificationReceived I have custom behavior, like saving the notification in a local LiteDB Database, and the method is NOT called when notification is received.

The notification is received when app is closed (or terminated by swipe on recent apps screen on Android) but no handle methods are called.

@jkasten2 can you please reopen this issue for investigation? Thank you so much!

I have the same issue here... @rgomezp Please suggest

[rgomezp]

Please take another look at our documentation regarding background notifications and make sure you have followed the instructions carefully and understand the limitations.

[MoonAndorid7]

@rgomezp Yes, I have checked this document and I have followed all its instructions. And I am not forced closing the application. I am simply swipe closing it.

it is working well when the application is in the background. HandleNotificationOpened is not calling when the application is not in the background. for ios, it is working fine altho

[rgomezp]

@MoonAndorid7 , It sounds like you're talking about notifications that arrive while the app is in focus and then are tapped, correct? You followed the example here?

If the app is in focus, you can use HandleNotificationReceived
