Question

I’m trying to make custom suggestion to search dialog. I’m using a urimatcher to match uri. But it dont work. I always get the exception ” java.lang.IllegalArgumentException: Unknown Uri: content://com.simple.search.SuggestionProvider/search_suggest_query/?limit=50″. Please explain this to me. What can I do to resolve this?

private static final UriMatcher sURIMatcher = makeUriMatcher();
public Cursor query(Uri uri, String[] projection, String selection,
        String[] selectionArgs, String sortOrder) {
    // Use UriMatcher, to find out what type of request received. Next, form
    // the corresponding query to the database
    switch (sURIMatcher.match(uri)) {
    case SEARCH_SUGGEST:
        if (selectionArgs == null) {
            throw new IllegalArgumentException(
                    "selectionArgs must be provided for the Uri: " + uri);
        }
        return getSuggestions(selectionArgs[0]);
    case SEARCH_TESTS:
        if (selectionArgs == null) {
            throw new IllegalArgumentException(
                    "selectionArgs must be provided for the Uri: " + uri);
        }
        return search(selectionArgs[0]);
    case GET_TEST:
        return getRecord(uri);
    default:
        throw new IllegalArgumentException("Unknown Uri: " + uri);
    }

makeUrimatcher

private static UriMatcher makeUriMatcher() {

    UriMatcher matcher = new UriMatcher(UriMatcher.NO_MATCH);
    // For the record
    matcher.addURI(AUTHORITY, "tests", SEARCH_TESTS);
    matcher.addURI(AUTHORITY, "tests/#", GET_TEST);
    // For suggestions table
    matcher.addURI(AUTHORITY, SearchManager.SUGGEST_URI_PATH_QUERY,
            SEARCH_SUGGEST);
    matcher.addURI(AUTHORITY, SearchManager.SUGGEST_URI_PATH_QUERY + "/*",
            SEARCH_SUGGEST);
    return matcher;
}

To avoid discussion i’ll change this answer if you provide more information…

but for now …

you have android:searchSuggestIntentData="content://com.simple.search.SuggestionProvider/tests" in xml

so you have to change

private static UriMatcher makeUriMatcher() {

    UriMatcher matcher = new UriMatcher(UriMatcher.NO_MATCH);
    // For the record
    matcher.addURI(AUTHORITY, "tests", SEARCH_TESTS);
    matcher.addURI(AUTHORITY, "tests/#", GET_TEST);
    // For suggestions table
    matcher.addURI(AUTHORITY, "tests/" + SearchManager.SUGGEST_URI_PATH_QUERY,
            SEARCH_SUGGEST);
    matcher.addURI(AUTHORITY, "tests/" + SearchManager.SUGGEST_URI_PATH_QUERY + "/*",
            SEARCH_SUGGEST);
    return matcher;
}

if you dont see differences i added “tests/”

so now it will match content://com.simple.search.SuggestionProvider/tests/search_suggest_query?limit=50 which is exactly what QSB will send …

anyway you can/should add limit to your query

case SEARCH_SUGGEST:
    if (selectionArgs == null) {
        throw new IllegalArgumentException(
                "selectionArgs must be provided for the Uri: " + uri);
    }
    final String limit = uri.getQueryParameter(SearchManager.SUGGEST_PARAMETER_LIMIT);
    return getSuggestions(selectionArgs[0], limit);

and then in getSuggestions

helper.getReadableDatabase().query(table, projection,
                    selection, selectionArgs, null, null, sortOrder, limit);

EDIT:

AUTHORITY + "tests/" + SearchManager.SUGGEST_URI_PATH_QUERY should be the same as android:searchSuggestIntentData !!!

EDIT2: from doc http://developer.android.com/guide/topics/search/adding-custom-suggestions.html

selection The value provided in the android:searchSuggestSelection
attribute of your searchable configuration file, or null if you have
not declared the android:searchSuggestSelection attribute. More about
using this to get the query below. selectionArgs Contains the search
query as the first (and only) element of the array if you have
declared the android:searchSuggestSelection attribute in your
searchable configuration. If you have not declared
android:searchSuggestSelection, then this parameter is null. More
about using this to get the query below.

add android:searchSuggestSelection=" ? "
