예, 알고 있습니다. 나와 다른 사람들은 전에도 비슷한 질문을했습니다. 그러나 내 구체적인 문제에 대한 도움을 찾고 있습니다. 나는이 코드를 다른 답변에서 그대로 그대로 복사 했으므로 여기서 내가 잘못 했습니까?Android POST HttpURLConnection을 만드는 방법

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"기능은 레이아웃의 버튼에서 onClick이라고합니다. 버튼을 누를 때마다 응용 프로그램이 충돌합니다. 뭐라 구요?

나는 대답을 노크하지 않고있다. (그것이 작동하고 광산이 아니기 때문에)하지만 나는 돌아가서 네가 가진 것을 다시 시작하는 대신에 내가 가진 것을 고치고 싶어한다. 내가 가진 것은 이미 다른 사람으로부터 복사 된 것입니다. 나는 당신을 복사하고 비슷한 문제가 생기면 나는 더 악취가납니다. – Truth

또한, 나는 이것이 어떻게 작동하는지 (복사 및 붙여 넣기뿐만 아니라) 배우는데 많은 관심이 있습니다. 왜 네 작품이 효과가 있고 광산이 그렇지 않은지에 대해 설명 할 수 있다면 훨씬 더 도움이 될 것이다. – Truth
