Answer 1

Do this you can convert string to timeinMillis:

String givenDateString =s;
            Log.d("Pana", "The value of s is " + s);
            SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy HH:mm", Locale.ENGLISH);
            sdf.setTimeZone(TimeZone.getTimeZone("GMT+0530"));
            try {
                Date mDate = sdf.parse(givenDateString);
                timeInMilliseconds = mDate.getTime();
                Log.d("Pana ", "Date in milli :: " + timeInMilliseconds);

                Log.i("TAG", "System.currentTimeMillis() = " + System.currentTimeMillis());
            } catch (ParseException e) {
                e.printStackTrace();
            }

Hope this helps.

String s= names.get(i).getTime();
System.out.println("Value: " + s);
//value of s is 11:50 AM

Printed value is in "hh:mm a" format.

So you should write as

Date d = new Date();
SimpleDateFormat df = new SimpleDateFormat("hh:mm a");
d = df.parse(s);

Intent intent = new Intent(getBaseContext(), AlarmReceiver.class);
PendingIntent pendingIntent =PendingIntent.getBroadcast(getBaseContext(),     
RQS_1, intent, 0);
AlarmManager alarmManager(AlarmManager)getSystemService(Context.ALARM_SERVICE);    
alarmManager.set(AlarmManager.RTC_WAKEUP, d.getTime(), pendingIntent);

Try this code

Date m_date = new Date();
SimpleDateFormat m_dateFormat = new SimpleDateFormat("hh:mm a");
m_date = m_dateFormat.parse(s);
m_date.getTime();

I checked below code & it is working fine on my side

        Date m_date = new Date();
        SimpleDateFormat m_dateFormat = new SimpleDateFormat("hh:mm a");
        try
        {
            m_date = m_dateFormat.parse("11:50 AM");
        }
        catch (ParseException p_e)
        {
            p_e.printStackTrace();
        }
        m_date.getTime();
