c# - unity用android创建sqlite

Question

我正在尝试在android中创建一个sqlite db，但是当我在手机中尝试这个时，永远不要创建数据库......

static void obrirConn () {

        dbconn = (IDbConnection)new SqliteConnection ("URI=file:" + Application.persistentDataPath + "/Timmy_Game.db");

        dbconn.Open(); //Open connection to the database.
        dbcmd = dbconn.CreateCommand();

        dbcmd.CommandText = "create table IF NOT EXISTS `nivells` (`id` INTEGER NOT NULL UNIQUE, `temps` INTEGER, `puntuacio` INTEGER, PRIMARY KEY(`id`));";
        dbcmd.ExecuteNonQuery();

    }
