Android application using spreadsheet as DB

1) This app is for my department which enables easy access to students to choose courses in every semester. 2) So, there is a shared spread sheet whose responses will be recorded and the app when opened must show the semesters available and on clicking a semester it must display the available courses and its details. 3) The courses and its details must be pulled from the spreadsheet. 4) Each professor will fill the form and the the details will be stored in the rows of a spreadsheet 5) After clicking submit, the first screen must show the first coloumn of the spread sheet as list items and on clicking any of the item, its details must be displayed in the next page. Note- only the 5 line needs to be done, I have the code for the others
