SharedPreferences, PreferenceActivity problem
<p>I have in my settings.xml two CheckBoxes. 
Each checkboxes has same keys "ShowContactPhotosCheckBoxPref":</p>

<pre><code>&lt;PreferenceScreen
            android:title="Appearence"
            android:key="AppearencePref" &gt;
            ......
            &lt;PreferenceCategory
                android:title="Show Contact Photos"&gt;
                &lt;CheckBoxPreference 
                    android:title="Show Contact Photos" 
                    android:summary="@string/show_contact_photos_preference"
                    android:defaultValue="true"
                    android:key="ShowContactPhotosCheckBoxPref" /&gt;
            &lt;/PreferenceCategory&gt;
       ........
&lt;/PreferenceScreen&gt;

.......

&lt;PreferenceScreen
            android:title="Contact Options"
            android:key="ContactOtionsPref"&gt;
            &lt;PreferenceCategory 
                android:title="Show Contact Photos"&gt;
                &lt;CheckBoxPreference 
                    android:title="Show Contact Photos"
                    android:defaultValue="true"
                    android:key="ShowContactPhotosCheckBoxPref" /&gt;
            &lt;/PreferenceCategory&gt;
......            
&lt;/PreferenceScreen&gt;
</code></pre>

<p>After start app state of chekbox №1 = chekbox №2 = true.
When I click on chekbox №1(state unchecked) and then go to checkbox №2 - state checked, but in my SharedPreferences file state of ShowContactPhotosCheckBoxPref is false.
It is possible to synchronize these chekboxes?</p>
