Like I said before I am new to Android and I don’t hide it but I’ve started to like it so far. And now I’d like to show you an application which enables sending data to the servers remotely. Before I give you the code, just look at the screens how it looks.

But if you don’t care how it works just download the application from here:

• Source code: https://github.com/strife/AndroidSendToServer
• Package for android: https://github.com/strife/AndroidSendToServer/blob/master/bin/SendToServer.apk (non authorized)

It should be compatibile with 2.3.3 API.

Preview:

Here you can easly send your data to server, just like that. But first of all you have to change settings by clicking on proper link.

That how looks settings page

View after clicking on the button

How it works?

There is too many files to show, for that reason I decided to explain only few features.

How to make a progress bar?

It’s simple, in your Activity class you’ve got to create a class which will extends of AsyncTask it should look like that:

...
    
    private class postData extends AsyncTask<String, Void, String> {

    	private final ProgressDialog dialog = ProgressDialog.show(sendToServerActivity, "", 
    			"Saving data to server. Please wait...", true);

    	@Override
    	protected String doInBackground(String... params) {
    		// perform long running operation operation

    		SharedPreferences settings = context.getSharedPreferences(PREFS_FILE, 0);
    		String server = settings.getString("server", "");
    		
    		HttpClient httpclient = new DefaultHttpClient();
    		HttpPost httppost = new HttpPost(server);

    		try {
    			// Add your data
    			List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
    			nameValuePairs.add(new BasicNameValuePair("android", editText1.getText().toString()));     
    			httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

    			try {
    				httpclient.execute(httppost);
    			} catch (UnsupportedEncodingException e) {
    				e.printStackTrace();
    			}


    			// Execute HTTP Post Request
    			// ResponseHandler<String> responseHandler=new BasicResponseHandler();
    			// String responseBody = httpclient.execute(httppost, responseHandler);

    			// if (Boolean.parseBoolean(responseBody)) {
    			//	dialog.cancel();
    			// }


    		} catch (IOException e) {
    			// TODO Auto-generated catch block
    			Log.i("HTTP Failed", e.toString());
    		}    		
    		
    		return null;
    	}
...

And then if you’ve got already that construction you can simply run it. In my example it looks:

public void sendItNow(Button button1) {
    	button1.setOnClickListener(new View.OnClickListener() {
			
			public void onClick(View v) {
				// TODO Auto-generated method stub
				// check if every 
				boolean isValidate = validate(editText1.getText());
				
				if (isValidate) {
					// send to server and open progress dialog box
					new postData().execute(); // most important line
				}
			}
		});
    }

As you see I execute this class using .execute method.

PHP Script which saves data

<?php



if (isset($_POST['android'])) {

    file_put_contents("android.txt", $_POST['android']);

    echo 1;

}



?>

Note: File android.txt has to have proper chmod (777).

How to manage pages?

The feature which will be able to do that you can find in Manifest file. I’ve noticed it is a very important file, something similar to file which defines how to run application, I guess. In my case I wanted to get some pages (Main and Help/Configuration). So then my Manifest file looks:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="sendto.server"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="10" />
    <uses-permission android:name="android.permission.INTERNET"/>

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:label="@string/app_name"
            android:name=".SendToServerActivity" >
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name="HelpActivity"></activity>
    </application>

</manifest>

What exactly I mean by “Pages”, you can find out by clicking link below:

• Creating new Activities in Android (available soon)

When you want to get it you should make some improvements. First of all just create a new field in your database it will be called “nb_photos” in my case. And then:

1. Open AdminProducts.php file (/[admin_panel]/tabs/AdminProducts.php) and add this line (line 2194):

<tr> 
    <td class="col-left">'.$this->l('Number of photos:').'</td> 
    <td style="padding-bottom:5px;"> 
        <input size="55" type="text" name="nb_photos" value="'.htmlentities($this->getFieldValue($obj, 'nb_photos'), ENT_COMPAT, 'UTF-8').'" style="width: 130px; margin-right: 44px;" /> 
        <span class="hint" name="help_box">'.$this->l('Number of photos') . '</span> 
    </td> 
</tr>

2. Open Product.php (classes/Product.php) and add:

Line 130

/** @var integer Number of photos */ 
public         $nb_photos;

Line 231

'ean13' => 'isEan13', 
'nb_photos' => 'isUnsignedInt', // this field
'upc' => 'isUpc',

Line 340

$fields['ean13'] = pSQL($this->ean13); 
$fields['nb_photos'] = pSQL($this->nb_photos); 
$fields['upc'] = pSQL($this->upc);

And that’s all. If you have any questions for that let me know

A couple days ago I decided to improve my programming skills by learning something new. And that thing is android. It’s a very powerful tool and I can say it for using it only for couple days. For me as a programmer beginning was easy. All variables, classes, constructions etc. are almost the same, of course Java is more powerful than PHP is but even though I can handle it : )

In next note I will put some code which may be interested for you. See you!

Fatal error (Message => message Length 1600)

// line 54
protected	$fieldsSize = array('message' => 16000); // just change to 16000

$product_id = 100; // this is your product id, in drupal it is node with product type
$quantity = 1; // amount of product
uc_cart_add_item($product_id, $quantity, array('attributes' => array(1 => 500)), NULL, NULL, $check_redirect = FALSE);
?>

function my_module_form_alter(&$form, $form_state, $form_id) {
  if($form_id == 'name_of_your_form') {
    $form['#after_build'][] = '_my_module_after_build';
  }
}
function _my_module_after_build(&$form, $form_state) {
    // here you should add that piece of code
    // 	$form['#redirect'] = 'your-page-after-submit'; 
  	$form['#submit'][] = 'my_module_action_after_submit';
    
}
function my_module_action_after_submit($form, &$form_state) {
 // and here you have all you want, you can modify $form_state variable
 // to change status or other variables in node
 // $form_state['values']['status'] = false;
   return $form_state;
}

And that’s all you should know about it. Now you can simply modify whatever you want to modify.

See you!

I had a huge problem with Prestashop (version 1.4.3) because I didn’t know how exactly I should get cart from Prestashop to the WordPress or somewhere else. However I spent some time to resolve that issue and I wrote that:

First of all we should get session data from Pretashop:

require_once dirname(__FILE__) . '/config/config.inc.php' ;
require_once(dirname(__FILE__) . '/config/settings.inc.php');
require_once dirname(__FILE__) . '/init.php' ; // this initializes the Cookie singleton, which is available in any script

function getAllCookies(){
global $cookie ;

// var_dump($cookie);

return $cookie;

}

$cookie = getAllCookies();

As you see you should add some lines from Prestashop configuration and then you should create a function in which you have cart ID. And then you can easily get all data from the cart:

$query = "SELECT p.id_product, pl.name, p.quantity, pp.price, p.id_product_attribute, pp.price * cu.conversion_rate AS orderprice, cu.sign, cu.format FROM ps_cart c
LEFT JOIN ps_cart_product p ON (p.id_cart = c.id_cart)
LEFT JOIN ps_product pp ON (pp.id_product = p.id_product)
LEFT JOIN ps_product_lang pl ON (pl.id_product = p.id_product)
LEFT JOIN ps_currency cu ON (cu.id_currency = c.id_currency)

WHERE c.id_cart = " . (int) $cookie->id_cart . " AND pl.id_lang = 1
ORDER BY p.date_add ASC";


$link1 = mysql_connect(_DB_SERVER_, _DB_USER_, _DB_PASSWD_);

if ($link1) {
$db_selected = @mysql_select_db(_DB_NAME_, $link1);
$res = mysql_query($query);
$arrProducts = array();
while ($row = mysql_fetch_assoc($res)) {
$arrProducts[] = $row;
}

var_dump($arrProducts); // all products from session cart
}

mysql_close($link1);

(Sorry for quality of code but I had to wrote this as  quick as possible)

And that’s all
