Question

I’m trying to make a login to my website via anAndroid app.
For some reason it always fail to login.

Here’s my login method for the app:

private void login() {

         //this method returns false
         HttpClient httpclient = new DefaultHttpClient();  
         HttpPost httppost = new HttpPost("http://mysite.com/mobileauth.php");
         JSONObject jsonObject = new JSONObject();

           try {  

               List nameValuePairs = new ArrayList(2);  
               jsonObject.put("username", "user1");
               jsonObject.put("password", "12345");

               nameValuePairs.add(new BasicNameValuePair("jsonString", jsonObject.toString()));               

               httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
               HttpResponse response = httpclient.execute(httppost);



               String responseStr = org.apache.http.util.EntityUtils.toString(response.getEntity());
               statusText.setText(responseStr);

           } catch (ClientProtocolException e) {  
               statusText.setText(e.toString());
           } catch (IOException e) {   
               statusText.setText(e.toString());
           } catch (JSONException e) {
               statusText.setText(e.toString());
           }
}

I created a specific file for mobile device login such as Android.

Here’s my authentication file on the server:

$host="*"; // Host name 
$username="*"; // Mysql username 
$password="*"; // Mysql password 
$tbl_name="users"; // Table name
$db_name="database";

$link = mysql_connect($host, $username, $password) or die("Connection Error"); 
$db = mysql_select_db("$db_name")or die("Connection Error");

$myusername = $_REQUEST['username']; 
$mypassword = $_REQUEST['password'];

$sql="SELECT * FROM $tbl_name WHERE username='$myusername' AND paswd='$mypassword'";
$result = mysql_query($sql);

$count = mysql_num_rows($result);

if ($count == 1) {
    $timeUpdateQuesry="UPDATE users SET lastLogin=Now() WHERE username='$myusername' AND paswd='$mypassword'";
    mysql_query($timeUpdateQuesry);

    echo("true");
} else {
    //happend without leaving page
    echo ("false");
}

For some reason I always get false in my status TextView.

I’ll appreciate any help

Thanks,

Remove all the JSON from your android code. You’re not receiving it as JSON on the PHP side, so this is probably a root cause. The NameValuePairs should work fine.
