Question

I’ve created this code to save a pdf file in sd card, but I want to change the directory that has the saved files, from /sdcard/, to /sdcard/MYDIR/

 try {
            URL url = new URL(f_url[0]);
            URLConnection conection = url.openConnection();
            conection.connect();
            // getting file length
            int lenghtOfFile = conection.getContentLength();

            // input stream to read file - with 8k buffer
            InputStream input = new BufferedInputStream(url.openStream(), 8192);

            // Output stream to write file
            OutputStream output = new FileOutputStream("/sdcard/yes.pdf");

Answer 1

To create a directory in Java, use mkdir() or mkdirs() on File.

To correctly create a directory or file on external storage on Android, do not hard-code /sdcard, largely because it is the wrong value on most Android devices. Use Environment.getExternalStorageDirectory() to access the root of external storage.

File dir=new File(Environment.getExternalStorageDirectory(), "MYDIR");

dir.mkdir();

OutputStream output=new FileOutputStream(new File(dir, "yes.pdf"));
