How to save file from website to sdcard

You can use this method to download a file from the internet to your SD card:

public void DownloadFromUrl(String DownloadUrl, String fileName) {

   try {
           File root = android.os.Environment.getExternalStorageDirectory();               

           File dir = new File (root.getAbsolutePath() + "/xmls");
           if(dir.exists()==false) {
                dir.mkdirs();
           }

           URL url = new URL(DownloadUrl); //you can write here any link
           File file = new File(dir, fileName);

           long startTime = System.currentTimeMillis();
           Log.d("DownloadManager", "download begining");
           Log.d("DownloadManager", "download url:" + url);
           Log.d("DownloadManager", "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(5000);
           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.flush();
           fos.close();
           Log.d("DownloadManager", "download ready in" + ((System.currentTimeMillis() - startTime) / 1000) + " sec");

   } catch (IOException e) {
       Log.d("DownloadManager", "Error: " + e);
   }

}

You need to add the following permissions to your AndroidManifest.xml:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>

How to download all files from server to SD-card

I have solved the problem by adding ivy jar file as a library and then added following code.

        try {
            urlAudio = new URL("http://server/folder/uploadAudio");
        } catch (MalformedURLException e) {
            e.printStackTrace();
        }
        ApacheURLLister lister1 = new ApacheURLLister();
        try {
            myList = lister1.listAll(urlAudio);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;

Android - Saving a downloaded image from URL onto SD card

You will need to first create the directories and sub-directories where you want to create the files.
I see that you used the mkdir() method. Try mkdirs(), and it should work.

How to download a file from a server and save it in specific folder in SD card in Android?

Your download URL is not a link to any file. It's a directory. Make sure its a file and exists. Also check your logcat window for error logs. One more suggestion, its always better to do a printStackTrace() in catch blocks instead of Logs. Its gives a more detailed view of the error.

Change this line:

    URL url = new URL("http://myexample.com/android/");

to:

    URL url = new URL("http://myexample.com/android/yourfilename.txt"); //some file url

Next, in catch block, add this line:

e.printStackTrace();

Also in the directory path, it should be something like this:

File dir = new File(root.getAbsolutePath() + "/mnt/sdcard/myclock/databases");

instead of

File dir = new File(root.getAbsolutePath() + "/myclock/databases");

Next, make sure you have acquired permission for writing to external storage in Android manifest.
