Question

I have a search widget (SearchView), displaying custom suggestions while typing. I’ve followed official guide to add recent queries to suggestions, but I still have custom suggestions ONLY.
For each search, my fragment call this function (verified) :

private void addQueryToRecent(String query) {
    SearchRecentSuggestions suggestions = new SearchRecentSuggestions(getActivity(),
            MyCustomSuggestionProvider.AUTHORITY,
            MyCustomSuggestionProvider.MODE);
    suggestions.saveRecentQuery(query, "recent");
}

My suggestion provider seems ok :

public class MyCustomSuggestionProvider extends SearchRecentSuggestionsProvider {

public final static String AUTHORITY = "com.zgui.musicshaker.provider.MyCustomSuggestionProvider";
public final static int MODE = DATABASE_MODE_QUERIES | DATABASE_MODE_2LINES;

public MyCustomSuggestionProvider() {
    setupSuggestions(AUTHORITY, MODE);
}

@Override
public Cursor query(Uri uri, String[] projection, String sel,
        String[] selArgs, String sortOrder) {
    //retrieves a custom suggestion cursor and returns it
}
}

searchable.xml :

<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:hint="artist, track informations..."
android:label="@string/app_name"
android:queryAfterZeroResults="true"
android:searchSuggestAuthority="com.zgui.musicshaker.provider.MyCustomSuggestionProvider"
android:searchSuggestSelection=" ?" />

manifest :

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.intent.action.SEARCH" />
        </intent-filter>

        <meta-data
            android:name="android.app.searchable"
            android:resource="@xml/searchable" />
    </activity>
<provider
        android:name=".provider.MyCustomSuggestionProvider"
        android:authorities="com.zgui.musicshaker.provider.MyCustomSuggestionProvider"
        android:enabled="true" >
    </provider>

Acording to that post, I’m supposed to have a recent search db at data/data/app.package.name/databases/databasename.db, but I don’t seem to…
Or maybe am I supposed to add the “recent search suggestions” myself in the cursor that MyCustomSuggestionProvider.query() returns ? Any idea is welcome…

Found it: it wasn’t clear at all on Android Documentation, but I need to make the request myself and merge cursors in MyCustomSuggestionProvider.query():

Cursor recentCursor = super.query(uri, projection, sel, selArgs,
            sortOrder);
Cursor[] cursors = new Cursor[] { recentCursor, customCursor};
return new MergeCursor(cursors);

Make sure you have the same columns in both though…
