android 直連 mysql

注意：架設好mysql之後，需要用root執行以下命令，開放mysql遠程訪問。

grant all privileges on *.* to root@"%" identified by "root"
flush privileges

連接：

public static final String REMOTE_IP = "數據庫的IP地址 ";
    public static final String URL = "jdbc:mysql://" + REMOTE_IP + "/數據庫名稱?autoReconnect=true";
    public static final String PASSWORD = "root";

Connection conn = null;
try {
      final String DRIVER_NAME = "com.mysql.jdbc.Driver";
      Class.forName(DRIVER_NAME);
      conn =  DriverManager.getConnection(url, user, password);
} catch (ClassNotFoundException e) {
       conn = null;
} catch (SQLException e) {
       e.printStackTrace();
}
