How to catch an image capture event on Android?

I am trying to find a way to listen to a built-in Camera application Capture event. I want my application to be triggered each time a picture is taken.

Is it possible?

I read here

that it is impossible...

If it is impossible then, maybe, there is another way to achieve it? For example receive a new file event an开发者_如何学JAVAd check if the file is picture...

Impossible means impossible. :)

Unless you were to modify the Android platform yourself to override some of these security features and provide custom images which you would then flash onto individual devices, but I imagine that's not what you're looking for...
