Overriding HomeKey in Android JB and above

Question

How can we override the home key in Android JB and above.I have searched a lot of threads but those doesn't work for Latest android versions.Also this is possible as I have checked in some apps available in Play Store such as "Active LockScreen".

@Raghunandan ... yes it's definitely possible ...please check this app "Active LockScreen" on Play store — ddnith, Sep 27 '13 at 19:23
@Raghunandan I have already checked the link for whicj you have duplicated my question.It doesn't work. — ddnith, Sep 27 '13 at 19:32
@ddnith A quick question, do you just want to detect if user has pressed the`Home` key and do something on the key being pressed(and app goes to background)? Or you want to change its functionality completely? Or some other stuff. I understand that you want to override it. But what exactly you want to do with it? — Shobhit Puri, Sep 27 '13 at 19:59
@ShobhitPuri I want to change the functionality.I want to keep my activity in front even if HOME key is pressed.Actually I want to implement mu own lock screen. — ddnith, Sep 27 '13 at 20:06

you cannot override the home button for security reason. it is the only way a user can always leave an app

yes we can.. there is some way... check this app "Active LockScreen" – ddnith Sep 27 '13 at 19:20
the only way is to make your app a launcher – tyczj Sep 27 '13 at 19:22
which is exactly what that app is – tyczj Sep 27 '13 at 19:24
@JosephEarl How can we make our app lock Screen? – ddnith Sep 27 '13 at 19:24
@tyczj making an app Launcher is not an option.If I make my app Launcher it will ask to chose bw default launcher and my app each time user press the home key – ddnith Sep 27 '13 at 19:27
what you want to do is not an option really, there is a reason why it cant be done – tyczj Sep 27 '13 at 19:37

As of now I have found the way by making my app Launcher and let the user chose if he/she want to disable the home key functionality while App is running.While App is not in foreground My App fires Intent DEFAULT_LAUNCHER_INTENT to display the DEFAULT Launcher. I'll post if find another work around without making the app Launcher.
