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" />
Do not forget change package name in all java class and xml/searchable.xml
In my project I changed like this:
<searchable xmlns:android="//schemas.android.com/apk/res/android"
android:label="@string/search_label"
android:hint="@string/search_hint"
android:searchSettingsDescription="@string/settings_description"
android:searchSuggestAuthority="cz.okhelp.android.searchabledict.DictionaryProvider"
android:searchSuggestIntentAction="android.intent.action.VIEW"
android:searchSuggestIntentData="content://cz.okhelp.android.searchabledict.DictionaryProvider/dictionary"
android:searchSuggestSelection=" ?"
android:searchSuggestThreshold="1"
android:includeInGlobalSearch="true"
>
</searchable>

// .show();
}
})
.create();
alertDialog.show();
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(getApplicationContext(), e.getMessage().toString(), Toast.LENGTH_LONG)
.show();//("dialogModeFC", e.getMessage().toString());
}
}// end dialogModeFC
