android SQLiteConstraintException UNIQUE 제약이 실패했습니다

Question

어떻게이 예외를 해결할 수 있습니까? pleaz는 제가 그리드 뷰에 항목을 추가 할 수 있도록 도와 주지만 그리드 뷰의 마지막 항목을 클릭하면이 예외가 올바르게 삭제 된 항목을 표시하지만이 예외는 무엇이 던져 졌는지 나타냅니다. 내 코드

public class MyDataBase extends SQLiteOpenHelper { 
private static final int DATABASE_VERSION = 1; 
// Database Name 
private static final String DATABASE_NAME = "contactsManager"; 
// Contacts table name 
private static final String TABLE_CONTACTS = "contacts"; 
private static final String TABLE_DELETED = "deleted"; 
// Contacts Table Columns names 
private static final String KEY_ID = "id";

잘못은 내가 당신이 오류를 던지는 이유, 대체 솔루션은 사용자가 쿼리를 대체 할 수입니다 같은 값을 삽입 생각합니다. 코드 아래

시도 :

public void AddnewContact(photos todo)// this method to add new contact 
{ 
    SQLiteDatabase db = this.getWritableDatabase(); 
    ContentValues values = new ContentValues(); 
    values.put(KEY_NAME, todo.getImage()); 
    db.replace(TABLE_CONTACTS, null, values); // change this line to your code 
    db.close(); 
} 

기존 데이터를 이미 처리 할 수있는 쿼리를 대체 ... 해결되지
