Hello People its hard to figure out errors when you are new and even you got negative reputation in previous question so after 2 days hard research i still don't figure out the problem .

i am learning from newboston series in eclipse and some method are depreciated but i search it its does not matter in program for now later may be remove.

here is the code :

this is my prefs class.

 public class Prefs extends PreferenceActivity{

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    addPreferencesFromResource(R.xml.prefs);
}

//extra class for preference in 56 ;
        // stuck in depreciason method addpreffromresource.
}

i added activity in mainfiest:

   <activity
        android:name="com.example.androidme.Prefs"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="com.example.androidme.Prefs" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

and this is my menu button where i hit preference and starts my activity.

case R.id.preferences

    public boolean onOptionsItemSelected(MenuItem item) {
    // TODO Auto-generated method stub


    switch(item.getItemId())
    {
    case R.id.Aboutus:
            Intent i = new Intent(this,AboutUs.class);
            startActivity(i);
        break;

    case R.id.prefernces:
        Intent prefintent = new Intent(this,Prefs.class);
        startActivity(prefintent);

        break;

    case R.id.exit:
        finish();

        break;
        }
    return false;
}

and i got the errors in logcat:
