Error Converting String to JSON
===

Need help on android. Been having this error `Error Parsing data org.json.JSONException: Value <html> of type java.lang.String cannot be converted to JSONObject`

Below is the page that is giving me the error when i run it.


    public class Login extends Activity {

    //URL to get User Data
    private static String URL_GET = "http://10.0.2.2/android_connect/get_authentication.php";
	
    // JSON Node names
    private static final String TAG_SUCCESS = "success";
    private static final String TAG_USERS = "Users";
    private static final String TAG_EMAIL = "Email";
    private static final String TAG_PASSWORD = "Password";
    
    JSONParser jParser = new JSONParser();
    String dbPassword = null;
    // users JSONArray
    JSONArray Users = null;
    
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // setting default screen to login.xml
        setContentView(R.layout.login);
 
        Button btn = (Button) findViewById(R.id.btnLogin);
        
        
        // Listening to register new account link
        btn.setOnClickListener(new View.OnClickListener() {
 
            public void onClick(View v) {
            	
            	String password =  ((EditText) findViewById(R.id.password)).getText().toString();
            	new getAuthentication().execute();
            	
            	if (password.equals(dbPassword)) {
            		// Switching to Main screen
                    Intent i = new Intent(getApplicationContext(), EchoSphere.class);
                    startActivity(i);
            	}
            }
        });
    }
    class getAuthentication extends AsyncTask<String, String, String>{

		@Override
		protected String doInBackground(String... params) {
			
			runOnUiThread(new Runnable() {
                public void run() {
                    // Check for success tag
                    int success;
                    
                    try {
                    	String email = ((EditText) findViewById(R.id.email)).getText().toString();
                    	
                    	Log.d("email:", email);
			
						List<NameValuePair> params = new ArrayList<NameValuePair>();
			        	params.add(new BasicNameValuePair(TAG_EMAIL, email));
			        	
			        	JSONObject json = jParser.makeHttpRequest(URL_GET, "GET", params);
			        	Log.d("Password:", json.toString());
	    
		        		 success = json.getInt(TAG_SUCCESS);	   
		        		 
		        		if (success == 1) {
		        			Users = json.getJSONArray(TAG_USERS);
	        				JSONObject c = Users.getJSONObject(0);
	        				dbPassword = c.getString(TAG_PASSWORD);
	        				Log.d("DBPW:", dbPassword);
		        		}
		        				
			        	} catch (JSONException e) {
		                e.printStackTrace();
			        	}
		        	
		        		}
		                
					});
			return null;
		}
		 
    }
    }
    	
   

This is the PHP script, i've validated the PHP and it shows to be working.


    <?php
    // array for JSON response
    $response = array();
    
    // include db connect class
    require_once __DIR__ . '/db_connect.php';
    
    // connecting to db
    $db = new DB_CONNECT();
    
    // check for post data
    if (isset($_GET["Email"])) {
    $email = $_GET['Email'];
    
    // get a product from products table
    $result = mysql_query("SELECT Email, Password FROM Users WHERE Email = '$email'");

    if (!empty($result)) {
        // check for empty result
        if (mysql_num_rows($result) > 0) {
 
            $result = mysql_fetch_array($result);
 
            $user[] = array();
            $user["Email"] = $result["Email"];
            $user["Password"] = $result["Password"];
 
            // user node
            $response["Users"] = array();
 
            array_push($response["Users"], $user);
            
            // success
            $response["success"] = 1;
            
            // echoing JSON response
            echo json_encode($response);
        } else {
            // no product found
            $response["success"] = 0;
            $response["message"] = "No User found";
 
            // echo no users JSON
            echo json_encode($response);
        }
    } else {
        // no product found
        $response["success"] = 0;
        $response["message"] = "No User found";
 
        // echo no users JSON
        echo json_encode($response);
    }
    } else {
    
    // required field is missing

    $response["success"] = 0;
    $response["message"] = "Required field(s) is missing";
 
    // echoing JSON response
    echo json_encode($response);
    }
    ?>

The results is as shown

    {"Users":[{"0":[],"Email":"1","Password":"123"}],"success":1}

I do not know where the error lies at.
