Android Unable to update correct date when I select December as month from the picker

I am trying to update system time and date. Setting time works fine as i have system permissions in my app and application is signatured as system app also setting date works fine for Months Jan upto Nov, but when i select December as month it is setting month to Jan. this all is cause of i am adding 1 to month but in a case i dont add 1 it creates problem for every month. if I select Dec it is Showing Nov, if I am selecting Jan it works fine , When I select Feb it again selects Jan, If I select March it selects Feb. every time it is setting one month less than the selected one.

here is my code 

 private TimePickerDialog.OnTimeSetListener timePickerListener = new     TimePickerDialog.OnTimeSetListener() {
@Override
 public void onTimeSet(TimePicker view, int hourOfDay, int minutes) {
 mHour   = hourOfDay;
 mMinute = minutes;

 Calendar c = Calendar.getInstance();
 c.set(mYear, mMonth+1, mDay, mHour, mMinute);

 Intent intent = new Intent();
 intent.setAction(Action);
 intent.putExtra("time", c.getTimeInMillis());
 getContext().sendBroadcast(intent);

    }
};
 private DatePickerDialog.OnDateSetListener datePickerListener = new     DatePickerDialog.OnDateSetListener() {
  @Override
  public void onDateSet(DatePicker arg0, int arg1, int arg2, int arg3) {
  mYear = arg1;
  mMonth = arg2;
  mDay = arg3;

  mTimePickerDialog.show();
 }
};

at the other end 

long when = intent.getLongExtra("time", -1);

    if (DEBUG)
        Log.i(TAG, "Incoming time: " + when);

    if (when / 1000 < Integer.MAX_VALUE) {
        SystemClock.setCurrentTimeMillis(when);
    }

    Time time = new Time();


    TvManager tvmng = TvManager.getInstance();
    TimerManager timerMgr = null;
    if(tvmng!=null)
        timerMgr = tvmng.getTimerManager();

    time.set(when);

    try {

        timerMgr.setClkTime(time, true);

    } catch (TvCommonException e) {

        e.printStackTrace();

    }

Please correct the code as mentioned below.

Calendar c = Calendar.getInstance();
c.set(mYear, mMonth, mDay, mHour, mMinute);

remove the +1 you added after the month. When you set the month in calender than it should be between 0 to 11 when you pass month +1 and your month is 11 then it will be 11+1 =12 and calender consider it as Jan not December.

When you use the date selected for the purpose of showing to user then you have to add month+1 so it will show exact month , But when you pass it to calender again for the purpose of storing users selection store it as it is without adding +1 if you added it before then make it month-1 and then add to calender object. It should work as you expected.

Also look at my solution to over come the issue.

to get formatted date to display user 

 public static String getDate(Calendar calendar){
    String formattedDate;
    SimpleDateFormat format = new SimpleDateFormat("MMM dd,yyyy");
    formattedDate=format.format(calendar.getTime());
    return formattedDate;
}

To set date to calender instance after selecting date from date picker use it like below.

 DialogFragment newFragment = new DatePickerDialogFragment() {

        @Override
        public void onDateSet(DatePicker datePicker, int year, int month, int day) {
            super.onDateSet(datePicker, year, month, day);
            Calender curDateInstance=Calender.getInstance();
            curDateInstance.set(Calendar.YEAR, year);
            curDateInstance.set(Calendar.MONTH, month);
            curDateInstance.set(Calendar.DAY_OF_MONTH, day);
            txtPickUpDate.setText(DateUtils.getDate(curDateInstance));


        }
    };
