EACCES Permission denied file not found

I have mounted an external sd card (7.9GB). Following is the code I am using to transfer a raw audio file from my project to the sdcard. I am using JellyBean 4.2 version. I am able to achieve this using a fileManager app. So the sdcard definitely is writable.

        File storagedir = new File("/mnt/extsd");
        if (storagedir.isDirectory()) {
        String[] dirlist = storagedir.list();
        for (int i = 0; i < dirlist.length; i++) {
            System.out.println(dirlist[i]);
        }
        File file = new File(storagedir, "Audio.mp3");

        try {
            InputStream is = getResources().openRawResource(R.raw.audio);
            OutputStream os = new FileOutputStream(file);
            byte[] data = new byte[is.available()];
            is.read(data);
            os.write(data);
            is.close();
            os.close();
            Toast.makeText(getApplicationContext(), "Saved!", Toast.LENGTH_SHORT).show();
        } catch (IOException e) {
            Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_LONG).show();
        }

Manifest: 

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

But I get the File not found exception:

          java.io.FileNotFoundException: mnt/extsd/Audio.mp3 openfailed:
          EACCES (Permission Denied)

So, it turns out I made a really silly mistake. The path should have been:

               File storagedir = new File("/mnt/extsd/");

   I missed the 2nd backslash after extsd.

You ideally should not be using such hardcoded paths like that. You should be using the strings coming from http://developer.android.com/reference/android/os/Environment.html .

The main reason for this is because these strings CAN change and its up to the platform to return the correct values.
