Lost sheep finder in the white spaces, please.

 Being a motivated non-expert. I understand that higher frequencies
carry more data, are more line of sight,and are absorbed by smaller
conductive bodies - like rain drops AND that lower frequencies carry
less data, go through and around buildings and are not as easily
absorbed by small conductive bodies. People are also more comfortable
with, and have more history with, television signal frequency
radiation than cell phone radiation.  I understand there is some white
space around 54 MHz.

We talked about an Android appliance type location reporting phone
that kids could wear laced into their shoes. In the interest of not
slighting such a phone, parents could use the same device to find
missing children in public places where vision may be obscured. To
avoid ad nauseum.

I cannot think of a better, more technology (physical characteristics
of spectrum and public acceptance of spectrum) matched, use of white
space than lisensed appliance spectrum where the appliances use modern
signaling and can triangulate off known towers to reliably get
position in the interest of reliable location of children by their
parents.

There has to be enough subscription service to pay for the radios, but
first reliably determine and communicate location in these
environments.  I think that means low frequency spectrum that is
licensed.

2. A few menu questions...

Hi Folks,

I have been working working with Eclipse, the Android plug-in and the 1.1
SDK.  So far I quite like it and its bringing back memories of the BeOS's
API :)  I generally learn by doing, and I am stuck with some menu problems.
I want to create my menus using and XML file, and I can do that, but I can't
work out how to link up my menu values and the XML values for my case
statements.

I have the following XML file, res/menu/options_menu.xml:

<menu xmlns:android="http://schemas.android.com/apk/res/android">
 <item android:id="@+id/options_menu_settings"
    android:title="Settings" />
 <item android:id="@+id/options_menu_about"
          android:title="About" />
    <item android:id="@+id/options_menu_quit"
          android:title="Quit" />
</menu>
Creating the menu by inflating it using the following:

    public boolean onCreateOptionsMenu(Menu menu) {
     MenuInflater inflater = getMenuInflater();
     inflater.inflate(R.menu.options_menu, menu);
        return true;
    }

So far this works and draws the menu.

I have the following file res/values/strings.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>

<item name="options_menu_quit" type="id" format="integer">0</item>
</resources>

But how do I get the case statement and the XML to fit?  I would have
expected it to be something like this:

    /* Handles item selections */
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
        case options_menu_quit:
            finish();
            return true;
        }
        return false;
    }

But that doesn't work as the options_menu_quit can't be resolved.

My other question is about menu icons. I get that this code adds an icon to
the menu:

menu.add(0, MENU_QUIT, 0, "Quit")
    .setIcon(R.drawable.menu_quit_icon);

But if I am drawing a menu by inflating XML, how do I specify an icon there?
