They use queryIntentActivities(), which only returns activities. In the package manager, the four component types are completely disjoint, and there is simply no call you can make that will give you a mix of them. > BTW, does this mean that services will tend to only get 'sticky' > broadcast intents, intents intended explicitly for them from a given > activity or service, and the occasional intent that isn't handle by > any activity currently registered for it? Services are just completely different from receivers, which are different from activities. They don't receive any broadcasts at all. Neither do activities. Only receivers do. (One exception is that you can dynamically create a BroadcastReceiver and register it at runtime, but in that case it is not the component itself receiving the broadcast.) In other words: - You launch activities with startActivity(). - You send to receivers with sendBroadcast(). - You bind to services with bindService() (and make them run with startService(), but semantically this is not the same at all as starting an activity; we probably should have found a different verb to use here). -- Dianne Hackborn Android framework engineer [email protected] Note: please don't send private questions to me, as I don't have time to provide private support.
