Output of mysql database is html and js code

Hi I'm setting up a new test server by mysql and want to create a test app in android that get the username and password from client and if they correctly inputted, app show toast( yeaah + username )
but it show js and html code :(((
and at last of this toast is:
<noscript> this site requires javascript to work , please enable javascript in your browser or use a browser with javascript support </noscript>
This is the main activity :
package com.example.server;
import android.support.v7.app.ActionBarActivity;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.webkit.WebSettings;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends Activity {
public static String Res="";
public static String res="";
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
new GetData("http://aysam1388mohammad.gigfa.com/test1.php", "mohammadreza").execute();
Button btn=(Button) findViewById(R.id.Main_BTN_Click);
final TextView txt=(TextView) findViewById(R.id.Main_Txt);
btn.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
txt.setText(Res+"\n"+res);
}
});
}
}
this is the GetData class :
package com.example.server;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.net.URL;
import java.net.URLConnection;
import java.net.URLEncoder;
import android.os.AsyncTask;
public class GetData extends AsyncTask{
private String LInk;
private String USer;
public GetData (String Link,String User) {
LInk = Link;
USer=User;
}
protected String doInBackground(Object... arg0) {
try{
String data=URLEncoder.encode("Username1","UTF8")+"="+URLEncoder.encode(USer,"UTF8");
URL Link=new URL(LInk);
URLConnection Link_Connect=Link.openConnection();
Link_Connect.setDoOutput(true);
OutputStreamWriter WR=new OutputStreamWriter(Link_Connect.getOutputStream());
WR.write(data);
WR.flush();
BufferedReader Reader = new BufferedReader(new InputStreamReader(Link_Connect.getInputStream()));
StringBuilder Sb=new StringBuilder();
String Line=null;
while((Line=Reader.readLine())!=null) {
Sb.append(Line);
}
MainActivity.res=Sb.toString(); // "res"
MainActivity.Res="Yeeeeeeah"; // "res"
}catch(Exception e) {
MainActivity.Res="nooooo"; // "res"
}
return "";
}
}
I'm sorry because of my terrible English and thank you that read this stack.
oh I forget to say that I used a php file in mysql database to connect with my app.
this is php file:
<?php
$conect=mysql_connect("sql210.gigfa.com","gigfa_23465941","13882345");
mysql_select_db("gigfa_23465941_Db1",$conect);
$User=$_POST['username'];
$SqlQ="select * from User where Username='$User' ";
$result=mysql_Query($SqlQ);
$Row=mysql_fetch_array($result);
if($Row[0]){
print("yeah \n");
}else {print("noo");
}
print $Row[1];
mysql_close($conect);
?>

Jsoup.connection Throws error

I want to parse html pages and extract data but when I tried to connect with Jsoup it throws errors. when I connected using httpclient [String s = EntityUtils.toString(response.getEntity(), "UTF-8");] there was no problem the html page content I was able to store into a string. But with Jsoup I am not able to do it.Am I making some error?

I found "NoClassDefintionFound" error for Jsoup from logcat.
Got to Java build path of your android project >> Order and Export tab >> Check your Jsoup library.
After checking the Jsoup library , select it and move it up using UP button.
Then clean the project and run it again.

So this is where i am, i can flush data out but can not seem to receive it back in from the server i am fairly new at this and have got help in the past from this site. I am really stuck and running out of time
Any help would be great
And Thank you

There are two different types of Socket, one is used for connecting to a host, and the other one is used to listen for connections. What you want to do is before trying to connect, make a ServerSocket that listens to incoming connections to a specific port number and wait for a new connection, as such:
ServerSocket serverSocket = new ServerSocket(2000);
Socket s = serverSocket.accept();
This should be done in your AsyncTask before trying to connect to it (accept() is blocking so it will wait for an incoming connection). So, changing the following two lines with the above and calling the AsyncTask before trying to connect to it should do the trick:
InetAddress inet = InetAddress.getByName(getMyIp());
Socket s = new Socket(inet, 2000);

How to handle - Application has stopped working in Android

So I am trying to create an Android app which basically reads out the twitter feed according to the search query inside a UI. The feed that I need to display form the parsed JSON is the user name, handle, profile picture and the tweet.
Now I have created the whole thing and my code compiles but as soon as I run it the app opens and I write something in the search feed and hit enter - " Unfortunately, AppName has stopped working " I am attaching my logcat and my source code for reference.
*Solved the issue by removing set text from DoInBackground and then giving adequate permission for Android to access internet. The issue now is that as I try and display the profile picture, the URL gets displayed, not the image.

You can't call view functions like setText on another thread like an AsyncTask doInBackground function. You need to do it in onPostExecute.

but the thing is i am getting in Log is java.net.UnknownHostException:www.googleapis.com

You have to modify AndroidManifest.xml to grant permission of "android.permission.INTERNET"
Info from: http://android-er.blogspot.com/2011/09/query-and-parse-google-json.html

This looks a network issue. Use the code given here to access a website using java network api http://www.coderanch.com/t/440335/sockets/java/Access-website-Java-Code
This will allow you to track the actual error and once that is fixed you can use any JSON lib to parse the response from server.

Ah, if you're getting UnknownHostException that means your DNS server is not successfully resolving www.googleapis.com. I'd check to make sure that you actually have a working network connection.
