Inserting data into MySQL using http-post and AsyncTask doesn't work

I am making an app that needs to post some data in MySQL database. The code doesn't show any errors, but no data is sent. My php file and HttpPost seem to work fine - I tried changing the php file so that it already included the data and then it worked. Here's my php:
<?php
$username = "user";
$password = "password";
$hostname = "mysql.xxx.com";
//connection to the database
$dbhandle = mysql_connect($hostname, $username, $password)
or die("Unable to connect to MySQL");
echo "Connected to MySQL<br>";
//select a database to work with
$selected = mysql_select_db("myapp_xxx_com",$dbhandle)
or die("Could not select examples");
//retrieve the data
$street = $_POST['Street'];
$house = $_POST['House'];
$city = $_POST['City'];
$comment = $_POST['Comment'];
mysql_query ("INSERT INTO Address (Street, Number, City, Comment, TimeOrdered) VALUES('$street', '$house, '$city', '$comment', NOW())");
mysql_close($dbhandle);
?>
And here's my java code:

I based the code on this tutorial http://mobiledevtuts.com/android/android-http-with-asynctask-example/ . I hope someone can help me with this.

App not redirecting to next page after login

I made login page in my app, But i am getting problem when user input right user and pass it show on screen that User Found but app is not redirecting to next layout.
PHP code is:
<?php
$host="XXXXXXXXXXXXXX";
$username="aXXXXX62";
$password="XXXXXX";
$db_name="XXXXXn";
$tbl_name="mXXXXs";
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];
$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql);
$count=mysql_num_rows($result);
if($count==1){
echo "User Found";
session_register("myusername");
session_register("mypassword");
}
else {
echo "Wrong Username or Password";
}
?>

}
}
}
the APP show that user is authenticated but when but it is redirecting to the next page.
Please let me know what needs to be change?

You should get the entity from the response and create an input stream from it
HttpEntity entity = response.getEntity();
InputStream is = entity.getContent();
Then read from the input stream and check for the response needed.

I couldn't easily find a fully described example. But heres where i would start.
Look at content providers for managing your app data and accessing it and storing it for local use. The link below gives an extensive explanation of how content providers work. Though you don't have to use one.
http://www.satyakomatineni.com/akc/display?url=DisplayNoteIMPURL&reportId=2882&ownerUserId=satya
The android content provider example also shows this.
On your server at home look at providing a rest full service layer for your app to request the information from. Rather than perhaps trying to directly access the database iteself. Discussed to some extent here on what to do (not specifically how to do it) https://groups.google.com/forum/?fromgroups#!topic/android-developers/rzV9tYpQZ5Y%5B1-25%5D
Afraid i don't have coded examples.

unable to call method

I'm trying to implement ZXing barcode scanner into my program. After getting the scanned result, I wanted to parse the result to a method named getData() which belong to another Java class. No syntax error on IDE, but mysql.getData(contents) won't call the method no matter what. Please advise.

There are many problems here, such as:
the mysql variable is null when you use it in onCreate, you must declare it.
The localContext object in MySql is never initialized, which will cause another NullPointerException when you call getData(). You should create a constructor that accepts a Context object for the MySql class, and use that constructor when you're fixing the first problem. Alternatively you could pass a Context object to getData()
the getData() method accesses the network in the main/UI thread, which will cause another Exception. Call this method in a different thread or spin off a new thread within the method itself. You may want to use an AsyncTask

How to extract the URL following an HTTPPost in Android

I'm scratching my head at this problem that I can't seem to figure out. What I'm trying to do is extract the URL following the HTTPpost. This will allow me to go through the Oauth process.
Currently I'm extracting the whole website into my entity.
For example: The data will be posted to https://mysite.com/login and will redirect after the post to https://mysite.com/dashboard?code=3593085390859082093720
How does one extract the url?
If you need any more information or can direct me in the right direction, all is appreciated! Thank you!

if you set a redirect handler, you can get back from the response the location the server's sending you to. here's a snippet of code I was just playing with... (and I should point out, if you DON'T set a redirect handler, you'll just get redirected to the final destination, which might be the login screen itself)
DefaultHttpClient htc = getHttpClient();
htc.setRedirectHandler(new RedirectHandler() {
#Override
public boolean isRedirectRequested(HttpResponse response, HttpContext context)
{
Log.d(TAG, "isRedirectRequested, response: " + response.toString());
return false;
}
#Override
public URI getLocationURI(HttpResponse response, HttpContext context)
throws ProtocolException
{
Log.d(TAG, "getLocationURI, response: " + response.toString());
return null;
}
});
HttpResponse resp = null;
StringBuilder out = new StringBuilder();
try
{
HttpGet get = new HttpGet(spec);
resp = htc.execute(get);
for (Header hdr : resp.getAllHeaders())
Log.d(TAG, "header " + hdr.getName() + " -> " + hdr.getValue());
...
}
catch (Exception e)
{
Log.e(TAG, "Error connecting to " + spec, e);
return null;
}
