Android应用中是如何读取服务器中的图片的

public static Bitmap getImage(String path){      try {     HttpURLConnection conn = (HttpURLConnection) new URL(path).openConnection();     conn.setConnectTimeout(5000);     conn.setRequestMethod("GET");     System.out.println("tdw1");     if(conn.getResponseCode() == 200){       InputStream inputStream = conn.getInputStream();       Bitmap bitmap = BitmapFactory.decodeStream(inputStream);         return bitmap;     }   } catch (Exception e) {     e.printStackTrace();   }   return null; }
