Code Issues 265 Packages Projects Releases Wiki Activity

Few minor changes in preparation to the GCM migration:

Browse Source 
- fixed warnings (like un-thrown exceptions)
- fixed code that unregister in case of NotRegistered error
- updated server code to use AppEngine 1.7
- changed code so it can be used in a local app engine server
- added a new device type called gcm
- created a servlet that displays how many devices are registered per type (ac2dm, chrome, gcm)
- created a servlet used to send messages without the need for the chrome plugin
