See more:

date = formatter.parse(dateInString);
				time = (Date) formatterTime.parse(timeInString);
				Calendar current = Calendar.getInstance();

				Calendar cal = Calendar.getInstance();
				/*
				 * cal.set(DatePicker.g, pickerDate.getMonth(), pickerDate.getDayOfMonth(), pickerTime.getCurrentHour(),
				 * pickerTime.getCurrentMinute(), 00);
				 */
				cal.set(date.getYear(),date.getMonth(),date.getDay(),time.getHours(),time.getMinutes());//error i think so 

				if (cal.compareTo(current) <= 0)
				{
					// setAlarm(cal);
					// The set Date/Time already passed
					Toast.makeText(getApplicationContext(), "Invalid Date/Time", Toast.LENGTH_LONG).show();
				}
				else
				{
					 setAlarm(cal);
					 db.addContact(new Contact_details(name1, mobile_number1, home_number1, company_name1, jobtitle1, emailid1, date, time));
				}

What do you mean by "comparison dnt take place"?
Are you saying the code never reached the compare statement?

Then there is some other code that you have not shown which causes the problem, or an exception is being caught somewhere and thrown away. I suggest you get together with your debugger and trace through the execution path.

date = formatter.parse(dateInString);
time = (Date) formatterTime.parse(timeInString);
Calendar current = Calendar.getInstance();

Calendar cal = Calendar.getInstance();
/*
* cal.set(DatePicker.g, pickerDate.getMonth(), pickerDate.getDayOfMonth(), pickerTime.getCurrentHour(),
* pickerTime.getCurrentMinute(), 00);
*/
cal.set(date.getYear(),date.getMonth(),date.getDay(),time.getHours(),time.getMinutes());

if (cal.compareTo(current) <= 0)
{
// setAlarm(cal);
// The set Date/Time already passed
Toast.makeText(getApplicationContext(), "Invalid Date/Time", Toast.LENGTH_LONG).show();
}
else
{
setAlarm(cal);
db.addContact(new Contact_details(name1, mobile_number1, home_number1, company_name1, jobtitle1, emailid1, date, time));
}
This is the code i am using inside try catch and i am not getting any exception

OK so you are not getting an exception, but what are you getting? Have you used your debugger to trace through the code and see whare it is going?

I don't know what you are looking at, but see my solution below which was not difficult to find.

Your problem is that two of your method calls do not return the values that you think, as described in the documentation[^].
getYear returns the year since 1900, i.e. 114 for 2014.
getDay returns the day of the week, not the day of the month.
Your code should read:

Java

Calendar cal = Calendar.getInstance();
cal.set(date.getYear()+1900,date.getMonth(),date.getDate(),time.getHours(),time.getMinutes());

Although note that all these methods are now deprecated.

So when you said that comparison didn't take place, that was not quite true; it did take place, but always produced the wrong result.
