I am new android, i\'m making an app in which one can download files to downloads folder (using Download Manager). I can see pictures if i go to downloads folder in emulator
For your first question try
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
(available since API 8)
To access individual files in this directory use either File.list() or File.listFiles(). Seems that reporting download progress is only possible in notification, see here.
