Notifications in android by comparing the system time with database values using background service is not working properly
===

I am developing an android app.I wan to provide five notifications per day.I will store the notification time in sqlite database.Then I compare this db notification time with the devices time in a repeating loop using service.But the notification will not work properly.Forceclose appeared.I have given the two class files Third,java and MyService below.......I need the help

         Third.java

       public class third extends Activity {
