Here's some examples I wish were possible: Suppose I make an app able to handle (play) http audio steams (action=ACTION_VIEW, mimeType=audio/*). I'd really like to know which apps send this intent. Why ? So I can advertise them to users for added functionality, hence adding value to my app (and to the emitting app). Except for a few apps that I know send this intent, I have no idea of other potentially very useful apps doing the same. Another example. I write an app handling a list of images. I'd like to find another app able to display a *list* of images. Impossible, unless getting every image viewer app and looking at their regenerated manifest for the Intents they declare. Finally another example: some apps provide open (app-specific) APIs through Intents. When I mean open, I mean that receivers are knowingly exported for public use. It is impossible to find out about these APIs unless you know about them...or you find them by luck looking at regenerated manifest xml from APK like it happened to me recently. And think what can be done with a gigantic Intent metadata databse: app recommendations. I'm quite certain someone at Google already thought of all this and what could be done with Intent metadata. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
