Question

I’m downloading a picture on a android device from a SQL database; Everything works well, except that opening the Stream takes very long time (even if there is no picture to download). It takes approx 5 sec’s before the actual download starts. Here is my code snippet:

URL url = new URL(sUrl[0]);
URLConnection connection = url.openConnection();
connection.connect();

int fileLength = connection.getContentLength();

//input = connection.getInputStream();
InputStream input = new BufferedInputStream(url.openStream());


File file = new File(
        Environment
                .getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),
        "MyCameraApp" + "/testpic.jpg");
OutputStream output = new FileOutputStream(file);
byte data[] = new byte[1024];

//---blabla progressbar update etc..

The line InputStream input = new BufferedInputStream(url.openStream()); gives the problem. Any idea’s on how to speed things up?

I use this code to get a bitmap from a url. 🙂

Bitmap bitmap = null;
    URL imageUrl = new URL(url);
    HttpURLConnection conn = (HttpURLConnection)imageUrl.openConnection();
    conn.setConnectTimeout(30000);
    conn.setReadTimeout(30000);
    InputStream is = conn.getInputStream();
    OutputStream os = new FileOutputStream(f);

try
{
   byte[] bytes=new byte[1024];
   for(;;)
   {
      int count=is.read(bytes, 0, 1024);
      if(count==-1)
         break;
      os.write(bytes, 0, count);
    }
 }
 catch(Exception ex){}
os.close();
bitmap = decodeFile(f);
