Summary and Conclusion

  • First we implemented the tree structure using ExpandableListView into a Sliding Drawer. The required XML was parsed using XML Pull Parser.
  • This implementation was tested in Aakash tablet. The video files stored in the android device will be displayed through a List View in android.
  • Video View was used to display the video.
  • Seek to function was added with each topic to play the video from particular position. Both these features were integrated and again tested in the tablet. Menu for Bookmarks and Browse srt file was created using the Menu and Menu Items class in Android. For saving the new bookmarks Sqlite Database was used. For playing subtitles along with the video the corresponding file can be searched through a list of srt files.
  • After Every 15minutes there will be a quiz session for better understanding of the topic.
  • Transcripts also implemented for better understanding so that user can simultaneously listen and read the topic.
