I'm currently trying to implement a Search in my App. I followed Google's Tutorial but now, when i press the "Search"-Button (on the Device/Emulator), nothing appears. I'm not sure why.

My searchable.xml File:

<?xml version="1.0" encoding="utf-8"?>
<searchable
  xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/label_search"
    android:hint="@string/search_hint"
    android:includeInGlobalSearch="true"
  >

</searchable>

This is the Android Manifest part for the Search-Activity:

 <!-- Search Activity -->
 <activity android:name=".SearchNotes">
    <intent-filter>
        <action android:name="android.intent.action.SEARCH" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
    <meta-data android:name="android.app.searchable"
        android:resource="@xml/searchable" />
 </activity>

The Code which populates my ListActivity:

private void searchAndDisplay(String query){
    SQLiteDatabase db = db_con.getReadableDatabase();
    final Cursor c = db.rawQuery(
            "SELECT headline, id as '_id' FROM entry WHERE " +
            "(headline LIKE '%?%') OR (content LIKE '%?%') ",
            new String[]{query, query});
    this.startManagingCursor(c);
    final ListAdapter searchAdapter = new SimpleCursorAdapter(
            this,
            android.R.layout.simple_list_item_2, c,
            new String[] {"headline", "_id"},
            new int[] {android.R.id.text1, android.R.id.text2});
    this.setListAdapter(searchAdapter);
    db.close();
}

This doesn't work in the Emulator, neither on my Android-Device. What am I missing here?

Do you have

<activity android:name=".OtherActivity" ... >
    <!-- enable the search dialog to send searches to SearchableActivity -->
    <meta-data android:name="android.app.default_searchable"
               android:value=".SearchNotes" />
</activity>

inside your Activity tag? It can also be applied to the Application if you so choose.
