Android: getCapsActive return value
<p>From Android documentation:</p>

<pre><code>// Find out whether the caps lock is on.
// 0 is no, 1 is yes, 2 is caps lock on.
int active = MultiTapInputMethod.getCapsActive(txtView.getText());
</code></pre>

<p>I'm using the Android emulator, not an actual phone.  Do real Android phones have a 3-state Caps Lock key? If not, then what is returned when Cap Lock is on?</p>
