Apakah mungkin untuk menghubungkan aplikasi Android saya ke database mysql tanpa PHP.?

Yes, You can.

Anda harus menambahkan pustaka jar untuk mysql. Kemudian kode java yang akan terhubung ke server mysql.

import java.sql.DriverManager;

import android.database.SQLException;

import com.mysql.jdbc.Connection;
import com.mysql.jdbc.ResultSet;
import com.mysql.jdbc.Statement;


    public class SQLConnection {
        public static Connection conn = null;
        static void setConnection(String user,String pass,String urlServer,String dBase){   


              try
              {
                  String userName = user;
                  String password = pass;
                  String url = "jdbc:mysql://"+urlServer+"/"+dBase;

                  Class.forName ("com.mysql.jdbc.Driver").newInstance ();
                  conn = DriverManager.getConnection (url, userName, password);
                  System.out.println ("Database connection established");
              }
              catch (Exception e)
              {
                  System.err.println (e.getMessage());
              }
              finally
              {
              }


        }
        public static Connection getConnection(){
        return conn;
        }

    }
