If you change the package name, you have to add new package name in:
DictionaryProvider.java
Do not forget change package name in all java class and xml/searchable.xml
In my project I changed like this:
DictionaryProvider.java
public class DictionaryProvider extends ContentProvider {
String TAG = "DictionaryProvider";
// public static String AUTHORITY = "com.example.android.searchabledict.DictionaryProvider";
// change to your new package name
public static String AUTHORITY = "com.myweb.mysubdomen.searchabledict.DictionaryProvider";
public static final Uri CONTENT_URI = Uri.parse("content://" + AUTHORITY + "/dictionary");
// in AndroidManifest.xml
//change com.example.android to your package e.g. com.myweb.mysubdomen
<!-- Provides search suggestions for words and their definitions. -->
<provider android:name="com.example.android.searchabledict.DictionaryProvider"
android:configChanges="keyboard|keyboardHidden|orientation"
android:authorities="com.example.android.searchabledict.DictionaryProvider" />
<!-- Points to searchable activity so the whole app can invoke search. -->
<meta-data android:name="android.app.default_searchable"
android:configChanges="keyboard|keyboardHidden|orientation"
android:value=".SearchableDictionary" />
// I change like this:
<!-- Provides search suggestions for words and their definitions. -->
<provider android:name=".DictionaryProvider"
android:configChanges="keyboard|keyboardHidden|orientation"
android:authorities="cz.okhelp.android.searchabledict.DictionaryProvider" />
<!-- Points to searchable activity so the whole app can invoke search. -->
<meta-data android:name="android.app.default_searchable"
android:configChanges="keyboard|keyboardHidden|orientation"
android:value=".SearchableDictionary" />

In my project I changed like this:
<searchable xmlns:android="//schemas.android.com/apk/res/android"

android:hint="@string/search_hint"
android:searchSettingsDescription="@string/settings_description"
