    Hello, I am reasonably new to android development.
    Currently I am working on an app, that connects to my wamp server database table.
    Table contains simple information and a url to my picture.

    My Android app loads the database, but will no open the image.
    "Unable to decode stream: java.io.FileNotFoundException: http...... open failed: ..."

    Can you help my modify my code so that it would open the image from my list?

    My php code is:
    [HIGH]<?php

    /*
    * Following code will list all the products
    */

    // array for JSON response
    $response = array();


    // include db connect class
    require_once __DIR__ . '/db_connect.php';

    // connecting to db
    $db = new DB_CONNECT();

    // get all products from products table
    $result = mysql_query("SELECT *FROM products") or die(mysql_error());

    // check for empty result
    if (mysql_num_rows($result) > 0) {
    // looping through all results
    // products node
    $response["products"] = array();

    while ($row = mysql_fetch_array($result)) {
    // temp user array
    $product = array();
    $product["pid"] = $row["pid"];
    $product["name"] = $row["name"];
    $product["price"] = $row["price"];
    $product["description"] = $row["description"];
    $product["image"] = $row["image"];
    $product["created_at"] = $row["created_at"];
    $product["updated_at"] = $row["updated_at"];



    // push single product into final response array
    array_push($response["products"], $product);
    }
    // success
    $response["success"] = 1;

    // echoing JSON response
    echo json_encode($response);
    } else {
    // no products found
    $response["success"] = 0;
    $response["message"] = "No products found";

    // echo no users JSON
    echo json_encode($response);
    }
    ?>[/HIGH]

    My java class in adroid that reads the list items:
    [HIGH]
    public class AllProductsActivity extends ListActivity {

    // Progress Dialog
    private ProgressDialog pDialog;

    // Creating JSON Parser object
    JSONParser jParser = new JSONParser();

    ArrayList<HashMap<String, String>> productsList;

    // url to get all products list
    private static String url_all_products = "blabla/android_connect/get_all_products.php";

    // JSON Node names
    private static final String TAG_SUCCESS = "success";
    private static final String TAG_PRODUCTS = "products";
    private static final String TAG_PID = "pid";
    private static final String TAG_NAME = "name";
    private static final String TAG_PRICE = "price";
    private static final String TAG_DESCRIPTION = "description";
    private static final String TAG_IMAGE = "image";

    // products JSONArray
    JSONArray products = null;

    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.all_products);

    // Hashmap for ListView
    productsList = new ArrayList<HashMap<String, String>>();

    // Loading products in Background Thread
    new LoadAllProducts().execute();

    // Get listview
    ListView lv = getListView();

    // on seleting single product
    // launching Edit Product Screen
    lv.setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> parent, View view,
    int position, long id) {
    // getting values from selected ListItem
    String pid = ((TextView) view.findViewById(R.id.pid)).getText()
    .toString();

    // Starting new intent
    Intent in = new Intent(getApplicationContext(),
    EditProductActivity.class);
    // sending pid to next activity
    in.putExtra(TAG_PID, pid);

    // starting new activity and expecting some response back
    startActivityForResult(in, 100);
    }
    });

    }

    // Response from Edit Product Activity
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    // if result code 100
    if (resultCode == 100) {
    // if result code 100 is received
    // means user edited/deleted product
    // reload this screen again
    Intent intent = getIntent();
    finish();
    startActivity(intent);
    }

    }

    /**
    * Background Async Task to Load all product by making HTTP Request
    * */
    class LoadAllProducts extends AsyncTask<String, String, String> {

    /**
    * Before starting background thread Show Progress Dialog
    * */
    @Override
    protected void onPreExecute() {
    super.onPreExecute();
    pDialog = new ProgressDialog(AllProductsActivity.this);
    pDialog.setMessage("Loading products. Please wait...");
    pDialog.setIndeterminate(false);
    pDialog.setCancelable(false);
    pDialog.show();
    }

    /**
    * getting All products from url
    * */
    protected String doInBackground(String... args) {
    // Building Parameters
    List<NameValuePair> params = new ArrayList<NameValuePair>();
    // getting JSON string from URL
    JSONObject json = jParser.makeHttpRequest(url_all_products, "GET", params);

    // Check your log cat for JSON reponse
    Log.d("All Products: ", json.toString());

    try {
    // Checking for SUCCESS TAG
    int success = json.getInt(TAG_SUCCESS);

    if (success == 1) {
    // products found
    // Getting Array of Products
    products = json.getJSONArray(TAG_PRODUCTS);

    // looping through All Products
    for (int i = 0; i < products.length(); i++) {
    JSONObject c = products.getJSONObject(i);

    // Storing each json item in variable
    String id = c.getString(TAG_PID);
    String name = c.getString(TAG_NAME);
    String price = c.getString(TAG_PRICE);
    String description = c.getString(TAG_DESCRIPTION);
    String image = c.getString(TAG_IMAGE);

    // creating new HashMap
    HashMap<String, String> map = new HashMap<String, String>();

    // adding each child node to HashMap key => value
    map.put(TAG_PID, id);
    map.put(TAG_NAME, name);
    map.put(TAG_PRICE, price);
    map.put(TAG_DESCRIPTION, description);
    map.put(TAG_IMAGE, image);

    // adding HashList to ArrayList
    productsList.add(map);
    }
    } else {
    // no products found
    // Launch Add New product Activity
    Intent i = new Intent(getApplicationContext(),
    NewProductActivity.class);
    // Closing all previous activities
    i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    startActivity(i);
    }
    } catch (JSONException e) {
    e.printStackTrace();
    }

    return null;
    }

    /**
    * After completing background task Dismiss the progress dialog
    * **/
    protected void onPostExecute(String file_url) {
    // dismiss the dialog after getting all products
    pDialog.dismiss();
    // updating UI from Background Thread
    runOnUiThread(new Runnable() {
    public void run() {
    /**
    * Updating parsed JSON data into ListView
    * */
    ListAdapter adapter = new SimpleAdapter(
    AllProductsActivity.this, productsList,
    R.layout.list_item, new String[] { TAG_PID,
    TAG_NAME, TAG_PRICE, TAG_DESCRIPTION, TAG_IMAGE},
    new int[] { R.id.pid, R.id.name, R.id.price, R.id.description, R.id.image });
    // updating listview
    setListAdapter(adapter);
    }
    });

    }

    }
    }[/HIGH]

    from the list adapter goes to a simple xml.
    I understand that I am getting the error because I put my link as a string and never convert it to a image format, but I don't know hot to fix my list adapter so it would be able to do this.

    please help out and all answers are appreciated
