Android intent opens picture gallery, but not picture. Why?

I have a few pictures in my app, and I want to open them in the default viewer when the user taps on them. Here's my code:

Intent intent = new Intent(Intent.ACTION_VIEW);
Uri uri = Uri.parse("file://" + Environment.getExternalStorageDirectory().toString() + "/Pictures/mypic.jpg");
intent.setData(uri);
intent.setType("image/jpeg");

startActivity(intent);

The default viewer is indeed opened, but it shows its "home screen", showing all the folders and galleries. It doesn't display the selected picture.

What am I doing wrong?

With following code placed in a try block you can open any file: Add the catch blocks your self.

             String FileName = ...full path of file...

             MimeTypeMap map = MimeTypeMap.getSingleton();
             String extension = map.getFileExtensionFromUrl(FileName.toLowerCase().replace(" ", "")); // does not work with spaces in filename

             String mimetype = map.getMimeTypeFromExtension(extension);

            Toast.makeText(context, FileName + "\nMimeType: " + mimetype + "\nExtension: " + extension , Toast.LENGTH_SHORT).show();

            if ( mimetype == null )
                {
                mimetype = "text/plain";
                Toast.makeText(context, "MimeType: " + mimetype, Toast.LENGTH_SHORT).show();
                }



            String Url = "file://" + FileName;

            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setDataAndType(Uri.parse(Url), mimetype);    
            context.startActivity(intent);
