I'm not sure if you are supposed to start an activity in a
BroadCastReceiver. It doesn't say specifically not to, though.

http://developer.android.com/intl/de/reference/android/content/BroadcastReceiver.html

Receiver Lifecycle
A BroadcastReceiver object is only valid for the duration of the call
to onReceive(Context, Intent). Once your code returns from this
function, the system considers the object to be finished and no longer
active.

This has important repercussions to what you can do in an
onReceive(Context, Intent) implementation: anything that requires
asynchronous operation is not available, because you will need to
return from the function to handle the asynchronous operation, but at
that point the BroadcastReceiver is no longer active and thus the
system is free to kill its process before the asynchronous operation
completes.

In particular, you may not show a dialog or bind to a service from
within a BroadcastReceiver. For the former, you should instead use the
NotificationManager API. For the latter, you can use
Context.startService() to send a command to the service
