I am running my application on emulator with Android 2.2 and API level 8.
I have tested the following 2 lines in my code:
long diffInDays = TimeUnit.MILLISECONDS.toDays(diffInMs); // API Level 9
long diffInDays = TimeUnit.DAYS.convert(diffInMs,TimeUnit.MILLISECONDS); // API Level 1
I am using line above to convert time in Milliseconds to time in days but i get the following exception. Why?
