I have to get the time and date and pass it to the alarm manager to generate a notification ... so far I have tried the code that it only generated for one day ... when I give a new alarm, the old ones are deleted ... only the last set alarm time is given to the alarm and its notification is only for the last set ... please help me guys ... `

Calendar ca = Calendar.getInstance();
ca.setTimeInMillis(System.currentTimeMillis());
int hr = ca.get(Calendar.HOUR)*60*60*1000;
int hr1 = ca.get(Calendar.MINUTE)*60*1000;
int hr2 = ca.get(Calendar.SECOND)*1000;

int cal = hr + hr1;

for(int y=1;y<h.length;y++){
    Toast.makeText(getApplicationContext(), "" +h[y],3000).show();
    String q[]=h[y].split(":");

    Integer i=Integer.parseInt(q[0]) * 60 * 60 * 1000;
    Integer i2=Integer.parseInt(q[1]) * 60 * 1000;

    long set= i + i2;
    long interval= set - cal;
    Toast.makeText(getApplicationContext(), "" +interval,3000).show();
    intr.add(interval);

    y++;
}
