Vous devez utiliser le URLConnection pour télécharger:
public void DownloadFromUrl(String imageURL, String fileName) { //this is the downloader method
try {
URL url = new URL("http://yoursite.com/" + imageURL); //you can write here any link
File file = new File(fileName);
long startTime = System.currentTimeMillis();
Log.d("ImageManager", "download begining");
Log.d("ImageManager", "download url:" + url);
Log.d("ImageManager", "downloaded file name:" + fileName);
/* Open a connection to that URL. */
URLConnection ucon = url.openConnection();
/*
* Define InputStreams to read from the URLConnection.
*/
InputStream is = ucon.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
/*
* Read bytes to the Buffer until there is nothing more to read(-1).
*/
ByteArrayBuffer baf = new ByteArrayBuffer(50);
int current = 0;
while ((current = bis.read()) != -1) {
baf.append((byte) current);
}
/* Convert the Bytes read to a String. */
FileOutputStream fos = new FileOutputStream(file);
fos.write(baf.toByteArray());
fos.close();
Log.d("ImageManager", "download ready in"
+ ((System.currentTimeMillis() - startTime)/1000)
+ " sec");
} catch (IOException e) {
Log.d("ImageManager", "Error: " + e);
}
}

IBM a une aide à ce sujet, essentiellement le fichier sera enregistré au InputStream , que vous pouvez utiliser à partir de là ou enregistrez-le dans un fichier.
