My intent is to customize an existing in-built app, say Phone app. Like when i end a call, I want to show some msgs/pictures at the end of call. I know it sounds wierd... but just giving an example. So is there any way that for such a small customization, I dont have to re- write full app and instead just get some event when call ends to do the customization ?
