Speedy GCM sends push notifications to Android devices via Google's GCM (Google Cloud Messaging for Android).

Pull requests are welcome!

• Simple Ruby implementation.
• No dependencies.
• Implemented against the JSON based service for GCM. If you need text/plain support look elsewhere.
• Validation of your message options.
• Test coverage
• Simple way to test your android client from the command line

##Installation

$ gem install speedy_gcm

##Requirements

An Android device running 2.2 or newer, its registration token, and a Google account registered for gcm.

Also, make sure 'net/http' and 'net/https' are available:

require "net/http"
require "net/https"

The 'shoulda' gem is required for testing:

$ gem install 'shoulda'

##Compatibility

Speedy_GCM will work with Rails 3.x & Ruby 1.9x. It has not been tested on previous versions or Rails or Ruby, and may or may not work with those versions.

##Usage

For a Rails app, a good place to put the following would be in config/initializers/speedy_gcm.rb :

GCM_API_KEY = "YOUR API KEY"

SpeedyGCM::API.set_account(GCM_API_KEY)

Then, where you want to make a GCM call in your code, create an message_options hash and pass it to send_notification():

message_options = {
  :registration_ids => [<array of registration ids>],
  # optional parameters below.  Read the docs here: http://developer.android.com/guide/google/gcm/gcm.html#send-msg
  :collapse_key => "foobar",
  :data => { :score => "3x1" },
  :delay_while_idle => false,
  :time_to_live => 1
}

response = SpeedyGCM::API.send_notification(message_options)

puts response[:code]  # some http response code like 200
puts response[:data]  # usually nil is returned

Note: there are blocking calls in both .set_account() and .send_notification(). You should use an async queue like Sidekiq to ensure a non-blocking code path in your application code, particularly for the .send_notification() call.

##Testing

To test, first fill out these variables in test/test_speedy_gcm.rb:

GCM_API_KEY = "TODO - Fill in with your GCM API Key"
TEST_PHONE_GCM_REGISTRATION_ID = "TODO - Fill in with some valid GCM Registration ID"

then run:

$ ruby test/test_speedy_gcm.rb
