Mark is right. Implementing a 'close box' under Android is a bad idea, because it is misleading to the user. The truth is that the Android OS does NOT support the notion of 'close' for apps. It implements a different paradigm, one more like SymbianOS (yechh!) than like Windows. The user leaves apps and enters others, but it is the system that decides to definitively CLOSE them, killing the hosting process.
Many Android apps really do follow this Symbian-like pattern, so it is reasonable to expect users to be used to it, even to prefer it in Android apps. Now I realize that many people have a spec from the client that asks for this close box. But in that case, the best procedure is to negotiate with the client, explaining why this is a bad idea, misleading to the users. If the client refuses to see the light, the closest you can get to a close box is to call Activity.finish() (on the current activity) after sending a message to all your other activities and possibly Services, BroadcastReceivers to do similarly (for a ordered Receiver this would be AbortBroadcast) But as Mark said, this is a bad idea. For one thing, "doing similarly" is not straightforward, since Services and BroadcatReceivers do NOT have a finish() method. And what about data connections? Are you going to have to shut down the ContentProviders too? Finally, look at the link Mark gave. It is a good explanation from a slightly different POV of why you should not do a close/exit box.
