connecting mysql from android with jdbc
- by manuraphy
hai i used the following code to connect mysql in local host from android.
it only displays the actions given in catch section . i dont know whether its a connection problem or not
package com.test1;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class Test1Activity extends Activity {
/** Called when the activity is first created. */
String str="new";
static ResultSet rs;
static PreparedStatement st;
static Connection con;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final TextView tv=(TextView)findViewById(R.id.user);
try
{
Class.forName("com.mysql.jdbc.Driver");
con=DriverManager.getConnection("jdbc:mysql://10.0.2.2:8080/example","root","");
st=con.prepareStatement("select * from country where id=1");
rs=st.executeQuery();
while(rs.next())
{
str=rs.getString(2);
}
tv.setText(str);
setContentView(tv);
}
catch(Exception e)
{
tv.setText(str);
}
}
}
when executes it displays "new" in the avd.
