Hi, A similar question has been asked before (with no answers as far as I can tell), but I thought I'd try my luck: Does anyone know whether there is a way to know whether there is anyone (anything) out there listening for a specific type of Intent being broadcast?
There are numerous applications out there that listen for specified intents, and do something when these intents are broadcast. For example, "Last.fm Scrobbler" applications. I would like to be able to tell, from a perferences screen, whether a given intent has a registered Receiver or not. This way, if a user chooses a scrobbler application and I detect that that scrobbler application does not appear to be registered/listening (or rather, there are no Receivers registered for that type of Intent), then I display an error/explanation message to the user, telling them that application is not installed or is disabled. The closest I've come to this from looking at the Android dev docs is "sendOrderedBroadcast". If the intended receivers of the broadcast can be guaranteed to cooperate by doing something predefined to the payload, then my broadcast receiver at the end should be able to detect the successful receipt vs lack of Receiver... This relies on a specific implementation on the part of the expected receivers, however, so it's not a very general solution. Any ideas? Thanks!
