Java 异常错误

我开发了一个应用程序，它可以将设备切换到静默模式，并在用户设定的给定时间内恢复正常。用户将输入事件名称，然后输入开始和结束时间，然后单击创建按钮创建事件。我运行了应用程序，用户在此时选择开始时间。我的应用程序崩溃并抛出一个我无法理解的异常。我正在发布下面的相关代码和异常错误

对于所需的流程，请尝试以下方法：

    Calendar calender = Calendar.getInstance();
    myTimePicker = new TimePickerDialog(this, new OnTimeSetListener() {

        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {


            Calendar newTime = Calendar.getInstance();

            //newTime.set(hourOfDay, minute); // remove this line

            //Add these two line
            newTime.set(Calendar.HOUR_OF_DAY, hourOfDay);
