Android POST HttpURLConnectionの作成方法

はい、わかっています。私と他の人たちはこれまで同様の質問をしてきました。私はしかし、私の特定の問題の助けを探しています。私はこのコードを他の回答から逐語的にコピーしました。そこで私はここで何が間違っていますか？Android POST HttpURLConnectionの作成方法

public void SendName(View v){ 
     EditText name = (EditText) findViewById(R.id.name); 
     String nombre = name.getText().toString(); 
     String parameters = "name="+nombre; 

     try{ 
      URL url2 = new URL("*****"); //I've got a correct URL here 
      HttpURLConnection connection = (HttpURLConnection) url2.openConnection(); 
      connection.setReadTimeout(15000); 
      connection.setConnectTimeout(15000); 
      connection.setRequestMethod("POST"); 
      connection.setDoOutput(true); 
      connection.setDoInput(true); 
      connection.setRequestProperty("Content-type", "application/x-www-form-urlencoded"); 

      OutputStream os = connection.getOutputStream(); 
      BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os, "UTF-8")); 
      writer.write(parameters); 
      writer.close(); 

      os.close(); 

     } catch (MalformedURLException e) { 
      e.printStackTrace(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
}

"SendName"関数は、レイアウト内のボタンからonClickと呼ばれます。そのボタンをクリックするたびに、アプリケーションがクラッシュします。何がありますか？
