How to close Cursor in getContentResolver for update method on android

Hi in my project I'm updating the database in for loop using the getContentResolver method. This is the coding I'm using for update the database

for(VOShoplyRetailer retailer:retailerMasterList){
            ContentValues retailerCV = retailer.parseToContentValues();
            int affectedRows = context.getContentResolver().update(DataContract.RetailerMasterEntry.RETAILER_MASTER_CONTENT_URI,
                    retailerCV,
                    DataContract.RetailerMasterEntry.COLUMN_RETAILER_ID+" = ?",
                    new String[]{retailer.getRetailerId()}
            );
        }

and I'm getting error as

03-20 11:55:45.279 6777-6786/com.example W/SQLiteConnectionPool﹕ A SQLiteConnection object for database '+data+data+com_example+databases+example_db' was leaked! Please fix your application to end transactions in progress properly and to close the database when it is no longer needed. 03-20 11:55:45.299 6777-6786/com.example W/CursorWrapperInner﹕ Cursor finalized without prior close()
