java - FileInputStream error when reading from uri

I have this bit of code :

protected String doInBackground(String... params) {


        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        FileInputStream fis;
        try {
            File F = new File(FilePath);
            fis = new FileInputStream(F);
            du.Upload(fis,Fname);             
        } catch (Exception e) {
            e.printStackTrace();
        }
      }

fis is generating the following error :

`java.io.FileNotFoundException: /storage/emulated/0/When We Are Young(AnyMaza.Com).mp3: open failed: EACCES (Permission denied)`

FilePath is like this :

/storage/emulated/0/When We Are Young(AnyMaza.Com).mp3

And I have added in my application manifest the read and write permissions :

What may be the problem ?

Any help appreciated.
