-To use this sample please do the following:
-
-1. Create a project in the [Google Developer Console](https://console.developers.google.com) (detailed instructions are availabl at https://developer.android.com/google/gcm/gs.html)
-1. Enable GCM support
-1. Create a copy of [config.sample.js](config.sample.js) called config.js
-1. Create a copy of [manifest.sample.json](manifest.sample.json) called manifest.json
-1. Replace `<Your Public API Key ...>` in your new `config.js` file with your own API key from the Google Developer Console project
-4. Replace `<Your Project Number ...>` in your new `manifest.json` with your own project number from the Google Developer Console project
