Hi everyone, I have questions on update ui by passing value from thread. These thread run every 5 second to update value on UI. I can not find the solution for this problem. Here is my sample code. If I use BindUtils.postNotifyChange then these thread will stop working and @NotifyChange is not update value to UI too.

Pls help.

    @Getter
    @Setter
    String emailBadgeNumber;

    @Getter
    @Setter
    String requestBadgeNumber;

@NotifyChange({"emailBadgeNumber", "requestBadgeNumber"})
private void updateBadgeNumber() {
ScheduledExecutorService service = Executors.newScheduledThreadPool(2);
Runnable task1 = () -> {
                // get data from database and pass value to UI.
                emailBadgeNumber = emails.isEmpty() ? 0 : emails.size();
                // BindUtils.postNotifyChange(this, "emailBadgeNumber");
            };
            Runnable task2 = () -> {
                // get data from database and pass value to UI.
                requestBadgeNumber = requests.isEmpty() ? 0 : requests.size();
                // BindUtils.postNotifyChange(this, "requestBadgeNumber");
            };
            service.scheduleAtFixedRate(task1, 0, 5, TimeUnit.SECONDS);
            service.scheduleAtFixedRate(task2, 0, 5, TimeUnit.SECONDS);
}
