I have noticed that some applications can be launched in place of a built-in Android application. When the Android application is opened, a "Complete action using" dialog pops up allowing the user to open a downloaded application instead. Can anyone tell me how to get the "Complete action using" dialog to pop up? Specifically, I want to pop up this dialog when opening the Android alarm clock, allowing the user to choose my alarm clock instead. I'm guessing I need to modify the manifest file for my application, but I'm not sure how. Some help would be appreciated. Thanks in advance.
