Re: [android-developers] Mimic Home button in software

I'm not sure I understand...  if you want to switch to home from your app (which I am pretty sure the intent you give below is the right way), what would this have to do with the keyguard?  If the user is in your app, they aren't in the keyguard...  I don't understand the connection you have between the two.

I would like the back button to work exactly like the home button in
my activity. I know that doesn't sounds like something I would want to
do, but it makes sense in the context of my app.

I've tried an intent:
Intent intent = new Intent(Intent.ACTION_MAIN, null);
intent.addCategory(Intent.CATEGORY_HOME);
startActivity(intent);
But this doesn't work the same way.
I've tried super.onKeyDown(KeyEvent.KEYCODE_HOME, event); on the
onKeyDown method and it does nothing.

They problem is the keyguard acts different when you push the home
button when you have an unlock pattern set.
There is usually a "Emergency Call" button on the unlock pattern
screen, but there is not when you click the home button and you have
dismissed the keyguard.
I would like the back button to behave the same way.

Would I be able to do this with the instrument class? Is there a
better way to do it?
