Call requires API level 24(current minimum is 12):android.icu.util.calendar

I am making a simple alarm app. Wherever I am using Calendar class it's showing an error same as title.

Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 10);
calendar.set(Calendar.MINUTE, 30);

Whenever I build my project, it builds fine but app crashes when it's launched on phone. Below is the Logcat:

I have a set my min SDK to be 11 but still it's not working.

Instead of importing android.icu.util.calendar, try importing java.util.Calendar.

The android.icu.util.calendar is the ICU replacement for java.util.Calendar but it's only available starting from API 24. So, it will only work on the devices which is API 24 and above.
