Hi, I am trying to download a video from url and save it in the internal app storage which can be viewed in the Downloaded Fragment. The problem is that when i click the download button video starts downloading and in notification bar downloading status also shows. But after download complete video is not appearing in the Downloaded Fragment. When i open the Downloaded Fragment there is a file name profileinstalled. this file remains there either i download or not. please help me with that
