Download a file programmatically on Android

Question

I am downloading files from web server programmatically. After download is completed, I checked the file. The size ,extension and all other parameters are correct but when I try to play that file in media player it is showing that it is corrupted.

Here is my code:

    byte[] b = null;     InputStream in = null;     b = new byte[Integer.parseInt(size)];    // size of the file.     in = OpenHttpConnection(URL);                 in.read(b);     in.close();      File folder = new File("/sdcard", "folder");    boolean check = folder.mkdirs();     Log.d("HttpDownload", "check " + check);     File myFile = new File("/sdcard/folder/" + name);       myFile.createNewFile();    OutputStream filoutputStream = new FileOutputStream(myFile);     filoutputStream.write(b);     filoutputStream.flush();     filoutputStream.close();

This is some working code I have for downloading a given URL to a given File object. The File object (outputFile) has just been created using new File(path), I haven't called createNewFile or anything.

private static void downloadFile(String url, File outputFile) {   try {       URL u = new URL(url);       URLConnection conn = u.openConnection();       int contentLength = conn.getContentLength();        DataInputStream stream = new DataInputStream(u.openStream());          byte[] buffer = new byte[contentLength];         stream.readFully(buffer);         stream.close();          DataOutputStream fos = new DataOutputStream(new FileOutputStream(outputFile));         fos.write(buffer);         fos.flush();         fos.close();   } catch(FileNotFoundException e) {       return; // swallow a 404   } catch (IOException e) {       return; // swallow a 404   } }
