Here is my code:

Answer 1

You are trying to run your app on a device (or simulator) with an API level below 26. LocalDate and the rest of java.time were introduced in level 26. However, there is a backport that allows you to use the most used 80 % of it on earlier Android versions. I suggest that this is a good solution for you.

So add the ThreeTenABP library to your project. And make sure you import org.threeten.bp.LocalDate and org.threeten.bp.DayOfWeek rather than the versions from java.time. Then you should be fine.

I was once told that dependencies is (I didn’t test):

compile group: 'org.threeten', name: 'threetenbp', version: '1.3.3', classifier: 'no-tzdb'

TemporalAdjusters

As an aside your code may be written as:

    LocalDate today = LocalDate.now(ZoneId.of("America/Tortola"));
    LocalDate monday = today.with(TemporalAdjusters.nextOrSame(DayOfWeek.MONDAY));
    LocalDate tue = today.with(TemporalAdjusters.nextOrSame(DayOfWeek.TUESDAY));
    LocalDate wed = today.with(TemporalAdjusters.nextOrSame(DayOfWeek.WEDNESDAY));
    LocalDate thur = today.with(TemporalAdjusters.nextOrSame(DayOfWeek.THURSDAY));
    LocalDate fri = today.with(TemporalAdjusters.nextOrSame(DayOfWeek.FRIDAY));
    LocalDate sat = today.with(TemporalAdjusters.nextOrSame(DayOfWeek.SATURDAY));
    LocalDate sunday = today.with(TemporalAdjusters.nextOrSame(DayOfWeek.SUNDAY));

I have used the following imports:

import org.threeten.bp.DayOfWeek;
import org.threeten.bp.LocalDate;
import org.threeten.bp.ZoneId;
import org.threeten.bp.temporal.TemporalAdjusters;
