UriMatcher не соответствует uri в ContentProvider Android

Question

Я реализую свой первый контент-провайдер. Я застреваю при попытке получить некоторый контент. Кажется, что UriMatcher не может сравниться с uri, который я прохожу.

Вот класс MyContentProvider:

public class MyContentProvider extends ContentProvider { 

private DataBaseHelper database; 


static final String TAG = "CONTENT"; 
// Used for the UriMacher 
public static final int ALL = 10; 


    public static final String AUTHORITY = "my.provider"; 

    private static final String BASE_PATH = "resources"; 
    public static final Uri CONTENT_URI = Uri.parse("content://" + AUTHORITY 
     + "/" + BASE_PATH); 

    public static final String CONTENT_TYPE = ContentResolver.CURSOR_DIR_BASE_TYPE 
     + "/all"; 
    public static final String CONTENT_ITEM_TYPE = ContentResolver.CURSOR_ITEM_BASE_TYPE 
     + "/one"; 

    private static final UriMatcher sURIMatcher = new UriMatcher(UriMatcher.NO_MATCH); 
    static { 
    sURIMatcher.addURI(AUTHORITY, BASE_PATH , ALL); 

    } 

@Override 
public boolean onCreate() { 
    database = new DataBaseHelper(getContext()); 

return true; 
} 
@Override 
public String getType(Uri uri) { 
String ret = getContext().getContentResolver().getType(CONTENT_URI); 
Log.i(TAG, "getType returning: " + ret); 
return ret; 
} 


@Override 
public Cursor query(Uri uri, String[] projection, String selection, 
String[] selectionArgs, String sortOrder) { 
    // Uisng SQLiteQueryBuilder instead of query() method 
    SQLiteQueryBuilder queryBuilder = new SQLiteQueryBuilder(); 

    // Set the table 
    queryBuilder.setTables(DataBaseHelper.MYTABLE); 

    int uriType = sURIMatcher.match(uri); 
    switch (uriType) { 
    case ALL: 
     break; 

    default: 
      // THIS LINE THROWS EXCEPTION!! 
     throw new IllegalArgumentException("Unknown URI: " + uri); 
    } 

    SQLiteDatabase db = database.getWritableDatabase(); 
    Cursor cursor = queryBuilder.query(db, projection, selection, 
     selectionArgs, null, null, sortOrder); 
    // Make sure that potential listeners are getting notified 
    cursor.setNotificationUri(getContext().getContentResolver(), uri); 

    return cursor; 
} 


    } 

А вот код, я использую при запросе MyContentProvider

 Uri.Builder builder = new Uri.Builder(); 
     builder.scheme ("content"); 
     builder.authority(MyContentProvider.AUTHORITY); 

     //builder.path (inURI.getPath()); 
     builder.path("resources"); 
     builder.appendPath(""+MyContentProvider.ALL); 

     Uri uri = builder.build(); 

     Cursor cursor = getContentResolver().query(uri, null, null, null, 
       null); 

Хотя вот мой LogCat:

Спасибо, для помощи.

Answer 1

Хорошо. Я ответил себе. Код для извлечения содержимого должен выглядеть следующим образом.

Uri.Builder builder = new Uri.Builder(); 
    builder.scheme ("content"); 
    builder.authority(MyContentProvider.AUTHORITY); 

    //builder.path (inURI.getPath()); 
    builder.path("resources"); 
     Uri uri = builder.build(); 

    Cursor cursor = getContentResolver().query(uri, null, null, null, 
      null); 

Проблема была в том, что я не понимал, что такое третий параметр addURI.
