Allow for blank Title or Message

[edborden]

Notifications won't post to notification bar unless both fields are set.

On which platform are you seeing this? iOS/Android/WP/all?

[edborden]

Only tested on Android 5

[EddyVerbruggen]

Hi, just tested Android 5 and these are my observations:

• Title & Message: OK
• Message only: OK
• Title only: no push is received on the device

Is this what you're seeing as well?

Also, how are you sending the messages? Telerik Backend, your own, etc?

[edborden]

Sending via Rails + GCM gem

Sending with message only, I was receiving notifications inside the app, with the app open. With the app closed or in background, nothing was being posted to the notification bar.

Sending with message & title, notifications now posted to notification bar while closed or in background.

[EddyVerbruggen]

Can I take a look at your code? Server and client, especially server? There must be a difference in our implementations as I can't reproduce it.

[AntonDobrev]

Just tested with independent server application and observed the same behavior as Eddy explained.

Title & Message: OK

"title": "title for the push", 
"message": "message for my app"

Message only: works as expected

 "message": "message for my app"

Title only: does not place the notification in the bar

"title": "title for the push"

Server:

gem 'gcm', require: 'gcm'

class GoogleCloudHandler

    def initialize reg_id
        @key = "AIzaSyCuNmd-up-Bus9PgQ1Q3xwdKMT4drRWppM"
        @reg_id = reg_id
    end

    def client
        @client ||= GCM.new @key
    end

    def send_message subject,body
        subject = "-" unless subject
        body = "-" unless body
        options = {data: {message: body,title:subject}, collapse_key: "update"}
        client.send([@reg_id], options)
    end

end

Client:
