For reference. the Context passed in the onReceive is that of the Application, not a specific Activity.

If you're doing anything that is context sensitive like dealing with preferences in your application, perhaps using appContext.getSharedPreferences. Use getApplicationContext() within your application to ensure the preferences will be read from both the BroadcastReceiver onReceive and the application itself. As the onReceive Context is that of the application, they will be equal.
