Market Bot is a web scraper (web robot, web spider) for the Google Play Android app store. It can collect data on apps, charts, and developers.
Google has recently changed the HTML and CSS for the Play Store. This has caused the release version of Market Bot to break. New code is in the master branch (unreleased) to begin fixing this problem. If you are interesed in helping then please join the discussion in issue 72.
Add this line to your application's Gemfile to use the latest stable version:
gem 'market_bot'
And then execute:
$ bundle
# Download/parse the app.
app = MarketBot::Play::App.new('com.facebook.katana')
app.update
# Print out the app title.
puts app.title
# Print all the other attributes you can find on an app object.
puts MarketBot::Play::App::ATTRIBUTES.inspect
Charts are defined by a collection and an option category.
# Download/parse the chart (collection=topselling_free, category=GAME).
chart = MarketBot::Play::Chart.new('topselling_free', 'GAME')
chart.update
# Print the first app.
puts chart.result.first.inspect
# Print all the chart collections & categories.
puts MarketBot::Play::Chart::COLLECTIONS.inspect
puts MarketBot::Play::Chart::CATEGORIES.inspect
# Download/parse developer.
dev = MarketBot::Play::Developer.new('Zynga')
dev.update
# Print the first app.
puts dev.result.first.inspect
Market Bot defaults to USA and English. You can specify a country and a language to override the defaults when creating objects:
chart = MarketBot::Play::Chart.new('topselling_paid', 'BUSINESS', country: 'jp', lang: 'ja')
chart.update
app = MarketBot::Play::App.new('com.facebook.katana', country: 'jp', lang: 'ja')
app.update
Google will block your IP address if you attempt to scrape large quantities of data.
