Android Passing Clock Time to Receiver

I am a beginner(apology in advance if question is too novice). I am trying to pass integer value of the "startHour" and "startMinute" that I get in the following class to my Receiver class and change the phoen setting to Vibration for the required time.

But while running when I try to run nothing happens, no change in the audio settings of the phone.

Main Class

    public void onClick(View v) {
    // TODO Auto-generated method stub
    Calendar c = Calendar.getInstance();
    switch(v.getId()){
    case R.id.startTime :
        // Process to get Current Time
        startHour = c.get(Calendar.HOUR_OF_DAY);
        startMinute = c.get(Calendar.MINUTE);

        // Launch Time Picker Dialog
        TimePickerDialog tpd1 = new TimePickerDialog(this,
                new TimePickerDialog.OnTimeSetListener() {

                    @Override
                    public void onTimeSet(TimePicker view, int hourOfDay,
                            int minute) {
                        // Display Selected time in textbox
                        eStart.setText(hourOfDay + ":" + minute);
                    }
                }, startHour, startMinute, false);
        tpd1.show();
        break;
    case R.id.stopTime :
        // Process to get Current Time
        stopHour = c.get(Calendar.HOUR_OF_DAY);
        stopMinute = c.get(Calendar.MINUTE);
        // Launch Time Picker Dialog
        TimePickerDialog tpd2 = new TimePickerDialog(this,
                new TimePickerDialog.OnTimeSetListener() {

                    @Override
                    public void onTimeSet(TimePicker view, int hourOfDay,
                            int minute) {
                        // Display Selected time in textbox
                        eStop.setText(hourOfDay + ":" + minute);
                    }
                }, stopHour, stopMinute, false);
        tpd2.show();
        break;

Receiver Class

public class AlarmReceiver extends BroadcastReceiver {

AudioManager audioControl;
Bundle extras;
int startHour,startMinute,stopHour,stopMinute;

@Override
public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    SimpleDateFormat sdf = new SimpleDateFormat("EEEE");
    Date d = new Date();
    String day = sdf.format(d);
    Calendar c = Calendar.getInstance();
    audioControl = (AudioManager) context
            .getSystemService(Context.AUDIO_SERVICE);
    extras = intent.getExtras();
    if(extras!=null){
        startHour = extras.getInt("startHour");
        startMinute = extras.getInt("startMinute");
        stopHour = extras.getInt("stopHour");
        stopMinute = extras.getInt("stopMinute");
    }

    int minute = c.get(Calendar.MINUTE);
    int hour = c.get(Calendar.HOUR_OF_DAY);
    if(day.equals("Monday")){

        if(hour>=startHour && hour<=stopHour){
            if(hour==startHour && minute>=startMinute){
                audioControl.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
            }
            else if(hour>startHour && hour<=stopHour){
                if(hour==stopHour && minute>stopMinute){
                    audioControl.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
                }
                else{
                    audioControl.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
                }
            }
        }
    }


}

}

Also once I press the back button from my main class screen the value of startTime and stopTime is erased.How can I store it so that the Receiver function can use it.
