Let us say you have a time picker in your xml file like the one below, pay attention to using spinner as the time picker's mode so that you can show TimePicker with intervals:

<TimePicker
    android:id="@+id/timepicker"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:timePickerMode="spinner"/>

Set setIs24HourView() to true in order to get rid of am/pm and call a function in which you will set the displayable value.

TimePicker timepicker = findViewById(R.id.timepicker);
timepicker.is24HourView();
setInterval(timepicker);

Finally, the setInterval() function should be like this depending on your need:

private void setInterval(TimePicker timePicker) {
        try {

            NumberPicker minutePicker = timePicker.findViewById(Resources.getSystem().getIdentifier(
                    "minute", "id", "android"));

            String[] display = new String[] { "0", "30" };

            minutePicker.setMinValue(0);
            minutePicker.setMaxValue(display.length - 1);
            minutePicker.setDisplayedValues(display);
        } catch (Exception ex) {
            Log.d(TAG, ex.getMessage());
        }
    }
