URL url="http://....";
 String FILENAME;
    InputStream input=new InputStream(url.openConnection()
    BufferedInputStream bis = new BufferedInputStream(input);
    fileDest=new File(FILENAME);

        if ( fileDest.exists() ){
            if ( ! fileDest.delete() )
                throw new Exception (
                        "impossible to delete "+ fileDest.getName());
        }
FileOutputStream fos = openFileOutput(FILENAME, Context.MODE_PRIVATE);
fos.write(bis.getBytes());
fos.close();

I guess you can start with this.
