Google Cloud Messaging Unique Key

I've read in Google Cloud Messaging documentation that GCM key is unique per device and per application. If I uninstall and reinstall the application the key is always the same, ie, the key is calculated based on some device and application identifiers or the key will change?

No, the key (called Registration ID) may change after you uninstall and re-install the app.

The following scenario will cause the ID to change :

  1. un-install the app
  2. send a GCM message to the device several times, until GCM server realizes that the app was uninstalled from the device
  3. re-install the app
