Am trying to schedule a notification with a list of time suppose i want to schedule the following time:
1. 22:00
2. 10:00
3. 17:00
This is how i tackled it ,
a). first i stored the time in Sqlite,
b).
then i used for each loop to make sure i insert the list of time in the scheduled manager, but the notification doesn't come.
Even when i tried to print in the
console, it shows that the time is available, but am wondering why the notification not working.
My codes are below:
public void MyLooper()
{
try
{
alarmService = new SetAlarmImplementation();
MedicationDatabase c = new MedicationDatabase();
//get schedulled time list
var alarm = c.GetAlarmList();
var username = c.GetUserName();
var hour = 0;
var minute = 0;
foreach (var list in alarm)
{
// This is the time i pick from the list
hour = Int32.Parse(list.Substring(0, 2));
minute = Int32.Parse(list.Substring(3, 2));
try
{
System.Diagnostics.Debug.WriteLine("Hour : " + hour + " Minutes : " + minute);
alarmService.SetAlarm(hour, minute, "Diabetics App", "Hello " + username + " , I remind you to take your insulin at this stated time");
}
catch (Exception e)
{
System.Diagnostics.Debug.WriteLine("Error " + e);
}
}
}
catch (Exception f)
{
}
}
But surprisingly if i insert directly time in the code like this it works fine :
alarmService.SetAlarm(13, 14, "Diabetics App", "Hello " + username + " , I remind you to take your insulin at this stated time");
How will i be able to register all the stored time in the alarm manager ?
EDIT
Alarm Implementation:
namespace Diabetes.Droid
{
public class SetAlarmImplementation : ISetAlarm
{
public SetAlarmImplementation() { }
public void SetAlarm(int hour, int minute, string title, string message)
{
Intent myintent = new Intent(Android.App.Application.Context, typeof(AlarmReceiver));
myintent.PutExtra("message", message);
myintent.PutExtra("title", title);
int _id = DateTime.Now.Millisecond;
TimeSpan ts = (DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc));
long millis = (long)ts.TotalMilliseconds;
int i = (int)millis;
PendingIntent pendingintent = PendingIntent.GetBroadcast(Android.App.Application.Context, i, myintent, PendingIntentFlags.OneShot);
Java.Util.Date date = new Java.Util.Date();
Java.Util.Calendar cal = Java.Util.Calendar.Instance;
cal.TimeInMillis = Java.Lang.JavaSystem.CurrentTimeMillis();
cal.Set(Java.Util.CalendarField.HourOfDay, hour);
cal.Set(Java.Util.CalendarField.Minute, minute);
cal.Set(Java.Util.CalendarField.Second, 0);
AlarmManager alarmManager = Android.App.Application.Context.GetSystemService(Android.Content.Context.AlarmService) as AlarmManager;
alarmManager.Set(AlarmType.RtcWakeup, cal.TimeInMillis, pendingintent);
}
}
}
My Alarm Receiver ?

{
var message = intent.GetStringExtra("message");
var title = intent.GetStringExtra("title");
