Question

Я получаю следующую ошибку, когда пытаюсь обновить строки в базе данных с помощью поставщика контента. предоставьте мне какое-либо решение

и код для поставщика контента.

public class BirthProvider extends ContentProvider { 
// fields for my content provider 
static final String PROVIDER_NAME = "com.javacodegeeks.provider.Birthday"; 
static final String URL = "content://" + PROVIDER_NAME + "/friends"; 
static final Uri CONTENT_URI = Uri.parse(URL); 

// fields for the database 
static final String ID = "id"; 
static final String NAME = "name"; 
static final String BIRTHDAY = "birthday"; 

// integer values used in content URI 
static final int FRIENDS = 1; 
static final int FRIENDS_ID = 2; 

DBHelper dbHelper; 

// projection map for a query 
private static HashMap<String, String> BirthMap; 

// maps content URI "patterns" to the integer values that were set above 
static final UriMatcher uriMatcher; 
    static{ 
     uriMatcher = new UriMatcher(UriMatcher.NO_MATCH); 
     uriMatcher.addURI(PROVIDER_NAME, "friends", FRIENDS); 
     uriMatcher.addURI(PROVIDER_NAME, "friends/#", FRIENDS_ID); 
    } 

    // database declarations 
    private SQLiteDatabase database; 
    static final String DATABASE_NAME = "BirthdayReminder";

    static final int DATABASE_VERSION = 1;

}

     return "vnd.android.cursor.item/vnd.example.friends"; 
     default: 
     throw new IllegalArgumentException("Unsupported URI: " + uri); 
     } 
} 

и вызов метода

String URL = "content://com.javacodegeeks.provider.Birthday/friends"; 
       Uri friends = Uri.parse(URL); 
       values.put(BirthProvider.BIRTHDAY, "true"); 
    getContentResolver().update(friends, values, values.get(BirthProvider.NAME)+"="+"'com.app.aroundu'", null); 

Какова фактическая ошибка сделано мной

Answer 1

getContentResolver().update(friends, values, values.get(BirthProvider.NAME)+"="+"'com.app.aroundu'", null); 

В здесь values.get(BirthProvider.NAME) возвращает строку com.example.home.myapplication.test, которая не является синтаксически правильным имя столбца.

Возможно, вы хотите только BirthProvider.NAME.
