What do you mean by 'detect home screen'?

 I've asked how to detect home screen before. I'm still searching...

 I noticed when I press home button on Android emulator, I got this
 statement in catlog:

 INFO/ActivityManager(584):
  Starting activity: Intent { action=android.intent.action.MAIN
 categories={android.intent.category.HOME} flags=0x1020 comp=
 {com.android.launcher/com.android.launcher.Launcher} }

 so I went to ActivityManager to see if I can find a clue there. Here
 is my findings:

 1. I can not instantiate ActivityManager because it's constructor is
 not public, and it's not a singleton
 2. it has a function called: getRunningAppProcesses sounds promising
 -- would it give me all the running processes?
 3. since I can not instantiate ActivityManager I tried to use one of
 the derived class: RunningAppProcesseInfo to see if I can use it's
 parent methods: getRunningAppProcesses. Nope.

 Am I on the right track or totally lost?

 Thanks,

 Sherry

[android-developers] Re: Still searching for HOME screen, and more question about ActivityManager

2009-06-05 Thread sherry 

my app would like to know if the phone or emulator's HOME screen is
displayed either by a way to detect (check some status or so) or
someone notify me (notification to interested parties).

In BREW, registered apps used to receive notifications if the HOME
(idle) screen is displayed. Based on that, apps may act differently.

Cheers,

Sherry

Home is an application like any other, it does not notify other apps
about when it comes to the front.
