Please don't call startActivity() from an IntentReceiver. This will pop your activity up in front of whatever they are doing, and they will likely curse you loudly.
I am not clear on exactly what you are trying to accomplish, but I suggest you back up a bit and look at how you want your application to behave when the user is working with it vs. when it is in the background. From that perspective, you probably shouldn't at all be using an IntentReceiver that is published in your manifest for this, since that IntentReceiver will run regardless of whether the user is currently using your app (which is the purpose of being able to publish intent receivers as top-level components). Instead, you may want to have your activity use registerReceiver() to monitor the phone state while it is running and perform an appropriate action when it is called -- for example calling startActivity() to switch to the next desired activity() followed by a finish() to close the current activity. Another approach you can take which may be much cleaner is to have a single activity that watches the phone state and just updates itself in response to that. This update could either be in the form of changing what it is displaying (such as by calling setContentView() with the desired layout to display), or it could be an ActivityGroup that switches between embedded activities based on the state.
