android - How do I specify a .Preference activity in the manifest.xml of a library activity -

i modeled code after tictactoe sample application, setup have application shell starts common activity in separate eclipse project flagged shared library ( properties->isalibrary ). have add the library calling activity's properties. invoke shared library code follows:

    private void startgame()     {  intent = new intent( this, calendar.class );  startactivityforresult( i, start_application );     } 

my androidmanifest calling activity follows:

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"  package="com.calendar" android:screenorientation="portrait"  android:versioncode="1" android:versionname="1.0">  <application android:label="@string/app_name"   android:debuggable="true" android:icon="@drawable/icon">    <activity android:name=".mainactivity"    android:screenorientation="portrait" android:label="@string/app_name"    android:configchanges="keyboardhidden|orientation">    <intent-filter>     <action android:name="android.intent.action.main" />     <category android:name="android.intent.category.launcher" />    </intent-filter>   </activity>          <!-- defined in calendarlib. right need manually copy              here. should merged automatically. -->         <activity              android:name="com.library.calendar" >         </activity>  <!--  <activity android:name=".preferences" android:label="@string/preftitle"--> <!--   android:screenorientation="nosensor">--> <!--   <intent-filer>--> <!--    <action android:name="com.calendar.library.preferences" />--> <!--    <catagory android:name="android.intent.catagory.preference" />--> <!--   </intent-filer>--> <!--  </activity>-->   </application>   <uses-sdk android:minsdkversion="4" />  <uses-permission android:name="android.permission.write_external_storage" />    <supports-screens android:anydensity="false"   android:resizeable="true" android:largescreens="true"   android:normalscreens="true" android:smallscreens="false" />  </manifest>  

the androidmanifest shared library follows:

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"  package="com.calendar.library" android:versioncode="1"  android:versionname="1.0">  <application android:icon="@drawable/icon" android:label="@string/app_name">   <!-- activity tag here not used. main project must     redefine activities used libraries.     later tools pick activities here , merge them automatically,     it's best define activities here regular android     project. -->   <activity android:name="calendar" />          <activity android:name=".preferences" android:label="@string/preftitle"             android:screenorientation="nosensor">             <intent-filer>                 <action android:name=".preferences" />                 <catagory android:name="android.intent.catagory.preference" />             </intent-filer>         </activity>   </application>  <uses-sdk android:minsdkversion="4" />  </manifest> 

i define menu in shared library code's activity class , invoke follows:

case menu_settings:      intent intent = new intent().setclass( this, preferences.class );      this.startactivityforresult( intent, 0 );      return true; 

when click on settings start_intent_not_resolved in method execstartactivity() in instrumentation.java. looking @ intent execstartactivity trying start see that

mpackage="com.barrett.calendar"  mclass="com.ifundraizer.calendar.library.preferences" 

and else null, not surprisingly.

my question is:

does definition of preferences activity belong in calling activity's manifest or in shared library's manifest , should definition of class in xml?

thank time, hope clear, confusing.

read comments in shared lib manifest:

<!-- activity tag here not used. main project tictactoemain          must redefine activities used libraries.          later tools pick activities here , merge them          automatically, it's best define activities here          regular android project.     --> 

basically need copy activities shared library manifest application uses activities. add application androidmanifest.xml:

<activity android:name=".preferences" android:label="@string/preftitle"         android:screenorientation="nosensor">         <intent-filer>             <action android:name=".preferences" />             <category android:name="android.intent.category.preference" />         </intent-filer> </activity> 

i see copied part, commented out. uncomment it.
