快速搜索android的问题

Question

Hi i'm trying to set up a quick search for my application but i only get a ClassNotFoundException after clicking the search button. I just want to show the user input in a Log. Here's what i got so far:

Manifets.xml

<activity android:name=".SearchActivity">
            <intent-filter>
                <action android:name="android.intent.action.SEARCH" />
            </intent-filter>

            <meta-data android:name="android.app.searchable"
                       android:resource="@xml/searchable" />
        </activity>

        <!-- declare the default searchable Activity for the whole app -->  
        <meta-data android:name="android.app.default_searchable"
                    android:value=".SearchActivity"/>

searchable.xml

<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/search_label"
    android:hint="@string/search_hint" >
</searchable>

SearchActivity.java

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.searchresults);

        final Intent queryIntent = getIntent();
        final String queryAction = queryIntent.getAction();
        if (Intent.ACTION_SEARCH.equals(queryAction)) {
            String searchKeywords = queryIntent.getStringExtra(SearchManager.QUERY);
            Log.i("YOU ENTERED", searchKeywords);
        }
    }

What i'm i doing wrong? Any help will be really appreciated.

Thanks!!

Well i solved my own problem. In the Mainefest.xml i changed the activity name to <activity android:name=".searchExample.SearchActivity"> i did the same in the meta-data outside the activity:

<!-- declare the default searchable Activity for the whole app -->  
        <meta-data android:name="android.app.default_searchable"
                    android:value=".searchExample.SearchActivity"/>

the thing is that android defines the package name in the Manifest under Manifest General Attributes and i changed some packages names in my project, but the manifest didn't got updated with my changes. So that's why i had to add this ".searchExample" which is the last name in the package where this activity is.

But anyways this is also the reason why we have to add a dot at the start of an activity name in the manifest, which i hadn't until today.
