Call the other package's activity in the Preference
<p>I add new class in the android/packages/apps/phone/src and I want to call the class in the ohter application.</p>

<p>Assume that the new class is SS.java
I added </p>

<pre><code>&lt;activity android:name="SS"&gt;&lt;/activity&gt; 
</code></pre>

<p>in the AndroidManifest.xml file in the android/packages/apps/phone folder.</p>

<p>The application which want to call the SS class has a list and I put the code in the xml file;</p>

<pre><code>&lt;PreferenceScreen
   android:title="@string/SS"&gt;
   &lt;intent
        android:action="android.intent.action.MAIN"
        android:targetPackage="com.android.phone"
        android:targetClass="com.android.phone.SS" /&gt;
</code></pre>

<p>When I choose the menu in the list, the phone show Class Not Found Exception.
The message isUnable to find explicit activity class {com.android.phone/com/android.phone.SS}; .... </p>

<p>Please let mw know what is the problem</p>
