String createTableSQL = "" 
       + " CREATE TABLE location(" 
       + " location_id INTEGER PRIMARY KEY AUTOINCREMENT," 
       + " location_name VARCHAR(30)," 
       + " addr VARCHAR(30)," 
       + ")"; 

Answer 1

はAUTO_INCREMENTの最後の変更AUTOINCREMENTを削除し、PRIMARY KEY（location_id）を追加

String createTableSQL = "" 
      + " CREATE TABLE location(" 
      + " location_id INTEGER PRIMARY KEY AUTO_INCREMENT," 
      + " location_name VARCHAR(30)," 
      + " addr VARCHAR(30)," 
      + " PRIMARY KEY (`location_id `))";
