Android Getting to Blank Homescreen

Question

I am working on a tablet that will not feature all the navigation buttons, just powerup, so I need a way to go from an activity to show the home screen. What Intent action can i fire that is guaranteed to show clear homescreen? What intent\action fires when you click on the device button that takes you to homescreen. Thanks?

What tablet are you working on that doesn't have the HOME button? — WindsurferOak, Mar 26 '11 at 00:24
Thats part of the product design. Its a dedicated tablet to run just one app. — Androider, Mar 26 '11 at 03:02

just call the following code from any activity:

moveTaskToBack(true);

You may want to add a button of some sort to invoke this function. Good luck

so just context.moveTaskToBack(true) Is that what the button acctually does. – Androider Mar 26 '11 at 03:01

You could try and finish() all of your activities. Maybe in Application keep a ivar that is showHome, if true on resume() in each activity just call finish(). This is not really standard android behavior though.

Edit** If you want to fire their launcher you can checkout this thread: Going to home screen programmatically

ok. but in android if you push a certain button you always get back to home screen. What Intent is this sending out? – Androider Mar 26 '11 at 02:59

Untested Code:

      Intent intent = new Intent(Intent.ACTION_MAIN);
        intent.addCategory(Intent.CATEGORY_HOME);
        intent.setClassName("myPackage","myPackage.MyClass");
        intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
        try {
             startActivity(intent);
        }
        catch (Exception e)
        {
            Log.d(TAG,"myMethod",e);
        }
