Here is the link which you can refer for fetching data from server.
For Creating Web Service using PHP Click here
<?php
include("connect.php");
$result="";
//get data from users (name for user variable is p1 and p2
//here I am stroing this value to par1 and par2
//method i am using is GET
$par1=$_GET['p1'];
$par2=$_GET['p2'];
$eve = "select * from table where field1='$par1' and field2='$par2'";
$re = mysql_query($eve);
$response = array();
$posts = array();
while($rt = mysql_fetch_array($re))
{
$f1=$rt['field1'];
$f2=$rt['field2'];
break;
}
$posts[] = array('p1'=> $f1,'p2'=> $f2);

How do i connect mysql database and insert data into it using android code

I have mysql database on my hosting server
On simple android application I have feedback form and on submit I want to insert data into mysql database which is on server .
I tried google and found this following solution for local machine
how do I connect to my hosting server and mysql database without any php code?
public void insert()
{
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("id",id));
nameValuePairs.add(new BasicNameValuePair("name",name));
try
{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://10.0.2.2/insert.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
Log.e("pass 1", "connection success ");
}
catch(Exception e)
{
Log.e("Fail 1", e.toString());
Toast.makeText(getApplicationContext(), "Invalid IP Address",
Toast.LENGTH_LONG).show();
}
try
{
BufferedReader reader = new BufferedReader
(new InputStreamReader(is,"iso-8859-1"),8);
StringBuilder sb = new StringBuilder();
while ((line = reader.readLine()) != null)
{
sb.append(line + "\n");
}
is.close();
result = sb.toString();
Log.e("pass 2", "connection success ");
}
catch(Exception e)
{
Log.e("Fail 2", e.toString());
}
try
{
JSONObject json_data = new JSONObject(result);
code=(json_data.getInt("code"));
if(code==1)
{
Toast.makeText(getBaseContext(), "Inserted Successfully",
Toast.LENGTH_SHORT).show();
}
else
{
Toast.makeText(getBaseContext(), "Sorry, Try Again",
Toast.LENGTH_LONG).show();
}
}
catch(Exception e)
{
Log.e("Fail 3", e.toString());
}
}

Here
HttpPost httppost = new HttpPost("http://10.0.2.2/insert.php");
insert.php is mentioned means you have to put this file on server
just change the http://10.0.2.2/insert.php to the path of your server file path where the file is stored
Code for insert.php
// this variables is used for connecting to database and server
$host="yourhost";
$uname="username";
$pwd='pass';
$db="dbname";
// this is for connecting
$con = mysql_connect($host,$uname,$pwd) or die("connection failed");
mysql_select_db($db,$con) or die("db selection failed");
// getting id and name from the client
if(isset($_REQUEST)){
$id=$_REQUEST['id'];
$name=$_REQUEST['name'];}
// variable used to tell the client whether data is stored in database or not
$flag['code']=0;
// for insertion
if($r=mysql_query("insert into emp_info values('$name','$id') ",$con))
{
//if insertion succeed set code to 1
$flag['code']=1;
echo"hi";
}
// send result to client that will be 1 or 0
print(json_encode($flag));
//close
mysql_close($con);
?>
as mentioned in your code , this will get the value from server whether the data is stored or not by code=1 for stored and code = 0 for not stored
JSONObject json_data = new JSONObject(result);
code=(json_data.getInt("code"));
if(code==1)
{
Toast.makeText(getBaseContext(), "Inserted Successfully",
Toast.LENGTH_SHORT).show();
}
else
{
Toast.makeText(getBaseContext(), "Sorry, Try Again",
Toast.LENGTH_LONG).show();
}

Make a string from a View element

I have two seekbars in my main activity but I can only use one of them at a time, so I need to retrieve a value seekbarx and seekbary, store either of them in a string variable to use it forward. I already used onProgressChange and onStopTrackingTouch but I guess it doesn't hold the value long enough.
This is what I had for the seekbars

It prints in the LogCat touching Y bar. servo = servoy/ but when I want to use the servo value it prints null.
How can I hold the value for this string?

Try declaring your ProgressDialog inside the AsyncTask. Instead of as a Activity member variable.
public class Thetask extends AsyncTask<String, Void, Void>
{
