Exam 1 : Activities and Events

Develop an application that performs the following:
  • Display a TextView and a Button with text "Restore".
  • When the app is launched, the TextView should display the current system time in milliseconds.
  • When the device orientation is changed, the text displayed in the TextView should be changed from the time at which the activity was started to  the current orientation - Landscape or Portrait
  • Use the method in Activity that returns the WindowManager instance, retrieve the default Device instance from the WindowManager and set the rotation.
  • Do not use onConfigurationChanged to handle state across orientation changes.
  • When the "Restore" button is clicked, the text displayed in the TextView should revert back to the original system time that was displayed.
