    public static void setTimerMillis(Context context, long millis)
 { SharedPreferences sp = 
context.getSharedPreferences(SessionManager.FILE_USER, Context.MODE_PRIVATE); 
SharedPreferences.Editor spe = sp.edit(); spe.putLong(SessionManager.TIMER_MILLIS, millis); spe.apply(); }



       void setExamTimer() {
            setTimerColors();
            final long maxTimeToShow = 60000;            //testing
            final long lastTimeinMillisLeftSaved = TestyBookHelper.getTimerMillis(context); //take saved value from sharedpref
            final long intervalTime = 1000;
            donut_exam_timer.setMax((int) maxTimeToShow);
            CountDownTimer countDownTimer = new CountDownTimer(lastTimeinMillisLeftSaved, intervalTime) {
                @Override
                public void onTick(long millis) {
                    TestyBookHelper.setTimerMillis(context, millis);
                    String hms = String.format("%02d:%02d:%02d", TimeUnit.MILLISECONDS.toHours(millis),
                            TimeUnit.MILLISECONDS.toMinutes(millis) - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)),
                            TimeUnit.MILLISECONDS.toSeconds(millis) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));               System.out.println(hms);
                    donut_exam_timer.setText(hms);
                    donut_exam_timer.setProgress(millis);
                }
                @Override
                public void onFinish() {
                }
            };
            countDownTimer.start();
        }

  public static long getTimerMillis(Context context) {
    SharedPreferences sp = context.getSharedPreferences(SessionManager.FILE_USER, Context.MODE_PRIVATE);
    return sp.getLong(SessionManager.TIMER_MILLIS, 60000L);}

Well there are no API to pause or resume it. What you should do is cancel() the timer and store the time remaining in a variable. When the resume button is hit again, restart the timer with the value from the variable.
