VolleyMotion

A gem to add the Volley Library to your RubyMotion Android Project.

Volley is an HTTP library that makes networking for Android apps easier and most importantly, faster.

Currently supports GET, POST of Objects and Arrays as well as Basic Auth. Please submit a github issue if a feature you want to use it not supported, more than happy to look into it.

Add this line to your application's Gemfile:

gem 'volley_motion'

And then execute:

$ bundle

Or install it yourself as:

$ gem install volley_motion

Inside a RubyMotion Android project

motion create my_project --template=android

1. Ensure your project is using Bundler if you started your project with an old version of RubyMotion:

begin
require 'bundler'
Bundler.require
rescue LoadError
end

2. Ensure you have the internet permission in your Rakefile

app.permissions = [:internet]

3. Add this inside the app in your rakefile

app.volley

Adding this will add some files to your project that are required.

Inside of your activity create a request like the following example:

def fetch_list
  url = "http://example.com/api/list"
  success_listener = VolleyMotion::RequestListener.new(self, List)
  error_listener = VolleyMotion::ErrorListener.new
  get = VolleyMotion::JsonArrayRequest.new(url, success_listener, error_listener)
  VolleyMotion::RequestQueue.build(self).add(get)
end

Create a model (List):

class List
  attr_reader :list

  def initialize(json)
    # read your JSON response here for example:
    for i in 0..(json.length-1)
        object = json.get(i)
        # Your code here
    end
  end
end

Also add this method to your activity:

def update_display(lists)
  # do something with your object here like adding to a ListView
end

The Library also supports Basic Authentication, for example:

success_listener = VolleyMotion::RequestListener.new(self, Barcode)
error_listener = VolleyMotion::ErrorListener.new(self)

params = {}
params[Java::Lang::String.new("barcode")] = Java::Lang::String.new(@barcode)

post = VolleyMotion::PostAuthRequest.new(url, params, success_listener, error_listener)
post.username = @username
post.password = @password
VolleyMotion::RequestQueue.build(self).add(get)
