Estou desenvolvendo um aplicativo que usabarcode para obter as informações do produto dos itens após a digitalizaçãobarcode.

Eu não quero que o usuário instaleZXing barcode app separadamente então eu incorporado oZXing código no meu projeto. Então eu consegui obter obarcode ID number.

Eu quero pegar oinformação do produto gostarnome, fabricante, preço etc usando o número do código de barras usandogoogle search api para compras.

Aqui está o código que usei

<code>public class JSONExampleActivity extends Activity {

    TextView httpStuff; 
    DefaultHttpClient client; 
    JSONObject json;  

    final static String URL = "https://www.googleapis.com/shopping/search"; 
    String upc = "/v1/public/products?country=US&q=691464717759&restrictBy=gtin=691464717759";

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);          

        httpStuff = (TextView) findViewById(R.id.tvHttp); 
        client = new DefaultHttpClient(); 
        new Read().execute("items");                
    }

    public JSONObject products(String upc)  throws ClientProtocolException, IOException, JSONException {     
        StringBuilder url = new StringBuilder(URL); 
        url.append(upc);
        HttpGet get = new HttpGet(url.toString());     
        HttpResponse r = client.execute(get);   
        int status = r.getStatusLine().getStatusCode(); 

        if (status == 200) {
            HttpEntity e = r.getEntity();         
            String data = EntityUtils.toString(e);         
            JSONObject timeline = new JSONObject(data); 

            return timeline;    
        } 
        else {         
            Toast.makeText(JSONExampleActivity.this, "error", Toast.LENGTH_SHORT);         
            return null;  
        } 
    }  

    public class Read extends AsyncTask<String, Integer, String> {      
        @Override     
        protected String doInBackground(String... params) {         
            // TODO Auto-generated method stub         
            try {                
                json = products(upc);
                return json.getString(params[0]);         
            } catch (ClientProtocolException e) {             
                    // TODO Auto-generated catch block             
                    e.printStackTrace();        
            } catch (IOException e) {             
                    // TODO Auto-generated catch block             
                    e.printStackTrace();         
            } catch (JSONException e) {             
                    // TODO Auto-generated catch block            
                    e.printStackTrace();         
            }         
            return null;     
        }  

    @Override 
    protected void onPostExecute(String result){     
    httpStuff.setText(result);
    } 
}

Mas eu não estou recebendo nenhum texto no httpStuff.

Este é o logcat:
