November 2014 Market Snapshot has deployed PlayDrone to capture a few days worth of data.

PlayDrone Code

The code is research quality code. It's poorly documented, and have no test suite.

Most of the code lies in lib/ and app/models/.

I strongly discourage you to run the code and encourage you to use it only as a reference, but if you must, here are the basic steps to process an app in dev mode:

  1. Make sure you have Ruby and Java installed

  2. Make sure you have Elasticsearch and Redis running

  3. Run bundle install

  4. Run rails c

  5. Add a google account with Account.create(:email => 'email', :password => 'password', :android_id => 'id'). An android id can be generated with Android Checkin.

  6. Running Account.first_usable should not block, but return something.

  7. Run Stack.process_app(:app_id => 'com.facebook.katana').

  8. You should see the facebook app repo in the repos directory.

If you want to go in production and launch the crawler, you can use the PlayDrone Kitchen.

Follow the instructions, edit deploy/settings.rb and run cap deploy:setup and cap deploy.

If everything works out (good luck), you'll be able to kick of jobs from a rails console. Try Stack.process_app(:app_id => 'com.facebook.katana'), and PlayDrone should discover at least half of the market by looking at related apps. Note that to increase the throughput, you may need to add more Google accounts.

Here's what you can expect to see once everything is running in the graphite dashboard:
