Your assignment is to create a Note Pad app as described below.
Uses: File System, State Saving, Alternate Landscape Layout
App Requirements
 The app should act as a simple note pad, allowing the user to enter text notes.
 The note pad should display the last update date/time (which is the last save date/time – this should be
saved when the note is saved – not entered or editable by the user).
 Note text (and the saved time) should be automatically saved when the user presses the back arrow, home
button, etc. – any time the app goes into the Paused state.
 Note text (and the saved time) must be saved to the device’s internal file system. You can use either XML,
JSON or Externalization to do this – the choice is yours but no other options can be used.
 Note text (and the saved time) should be automatically loaded when the app goes into the Resume state.
 If no saved data file is present, the app should start with no text and the current date/time displayed as the
Last Update time. This situation should not results in any errors.
 The note text on the screen should have a scroll bar, because the text entered can be longer than the
displayed area.
 The app must use a different layout for landscape orientation (different than the portrait orientation layout)
– shown below. All data content must be present in both portrait and landscape orientations.
 Contents and practices discussed in class must be followed.
 The below is an example of how the app should look. Note, you do NOT need to make yours look exactly like
this, but the content here is limited to try to keep variation minimal.

 Landscape orientation has its own layout, and looks & works properly
 Proper use of Constraint Layout in both layouts
 All required information is present when rotating between orientations.
 Overall appearance is clean and professional
o 20% Input operation
 User text entry works properly – scrolls as needed.
 Text entry works as expected in both orientations.
o 40% Save & Restore
 Note text and the current date/time (last updated time) are saved when
Paused state is entered
 Note text and the saved current date/time are loaded when Resume state is
entered.
 App behaves appropriately if save-file is not present
