title: Disable specific dates of day in Android date picker
body: <p>I'm using the datePicker and I can disable last days of today and later days after 30 days by the following code:</p>
  
  <pre><code>DatePickerDialog datePicker = new DatePickerDialog();
  
               Calendar calender = Calendar.getInstance();
               long today = calender.getTimeInMillis();
               final long oneDay = 24 * 60 * 60 * 1000L;
  
               Date previousDays = new Date(today - 1000);
               datePicker.setMinDate(DateToCalendar(previousDays));
  
               Date nextMonth = new Date(today + 30 * oneDay);
               datePicker.setMaxDate(DateToCalendar(nextMonth));
  </code></pre>
  
  <p>If I want to disable Friday of every month, how can I do this?</p>
