Can't start intent service in xamarin.android - xamarin.forms

Question

Can't start intent service
I am writing code for synch data for every 10 minute whenapp is in forground,background or sleep . I had write weakfulintentservice for it calling it from Alaramreceiver but AppService doesn't get call.
AppService
public class AppService : WakefulIntentService
{
public AppService() : base("AppService")
{
}
protected override void DoWakefulWork(Intent intent)
{
Toast.MakeText(this, "In service", ToastLength.Short).Show();
Log.Info("AppService", "I'm awake! I'm awake!");
}
}
WeakFulIntentService
abstract public class WakefulIntentService : IntentService
{
abstract protected void DoWakefulWork(Intent intent);
public static string NAME = "com.jondouglas.wakeful.WakefulIntentService";
public static string LAST_ALARM = "lastAlarm";
private static volatile PowerManager.WakeLock lockStatic = null;
[MethodImpl(MethodImplOptions.Synchronized)]
private static PowerManager.WakeLock GetLock(Context context)
{
if (lockStatic == null)
{
PowerManager manager = (PowerManager) context.GetSystemService(Context.PowerService);
lockStatic = manager.NewWakeLock(WakeLockFlags.Partial, NAME);
lockStatic.SetReferenceCounted(true);
}
return (lockStatic);
}
public static void SendWakefulWork(Context context, Intent intent)
{
GetLock(context.ApplicationContext); //Possibly use of acquire here
context.StartService(intent);
}
public static void SendWakefulWork(Context context, Type classService)
{
SendWakefulWork(context, new Intent(context, classService));
}
public static void ScheduleAlarms(IAlarmListener alarmListener, Context context)
{
ScheduleAlarms(alarmListener, context, true);
}
public static void ScheduleAlarms(IAlarmListener alarmListener, Context context, bool force)
{
ISharedPreferences preferences = context.GetSharedPreferences(NAME, 0);
long lastAlarm = preferences.GetLong(LAST_ALARM, 0);
if (lastAlarm == 0 || force ||
(DateTime.Now.Millisecond > lastAlarm &&
DateTime.Now.Millisecond - lastAlarm > alarmListener.GetMaxAge()))
{
AlarmManager manager = (AlarmManager) context.GetSystemService(Context.AlarmService);
Intent intent = new Intent(context, typeof(AlarmReceiver));
PendingIntent pendingIntent = PendingIntent.GetBroadcast(context, 0, intent, 0);
alarmListener.ScheduleAlarms(manager, pendingIntent, context);
}
}
public static void CancelAlarms(Context context)
{
AlarmManager manager = (AlarmManager) context.GetSystemService(Context.AlarmService);
Intent intent = new Intent(context, typeof (AlarmReceiver));
PendingIntent pendingIntent = PendingIntent.GetBroadcast(context, 0, intent, 0);
manager.Cancel(pendingIntent);
context.GetSharedPreferences(NAME, 0).Edit().Remove(LAST_ALARM).Commit();
}
public WakefulIntentService(string name) : base(name)
{
SetIntentRedelivery(true);
}
public override StartCommandResult OnStartCommand(Intent intent, StartCommandFlags flags, int startId)
{
PowerManager.WakeLock wakeLock = GetLock(this.ApplicationContext);
if (!lockStatic.IsHeld || (flags & StartCommandFlags.Redelivery) != 0)
{
wakeLock.Acquire();
}
return base.OnStartCommand(intent, flags, startId);
return (StartCommandResult.RedeliverIntent);
}
protected override void OnHandleIntent(Intent intent)
{
try
{
DoWakefulWork(intent);
}
finally
{
PowerManager.WakeLock wakeLock = GetLock(this.ApplicationContext);
if (wakeLock.IsHeld)
{
try
{
wakeLock.Release();
}
catch (Exception ex)
{
Log.Error(Class.SimpleName, "Exception when releasing wakelock", ex);
//Log exception when releasing wakelock
}
}
}
}
public interface IAlarmListener
{
void ScheduleAlarms(AlarmManager manager, PendingIntent pendingIntent, Context context);
void SendWakefulWork(Context context);
long GetMaxAge();
}
CallToAppService
public void SendWakefulWork(Context context)
{
WakefulIntentService.SendWakefulWork(context, typeof(AppService));
}
The call for AppService context.StartService(intent); from weakfulintentservice execute perfectly
but AppService cant start In xamarin.android.
Kindly help me to solve this issue.

The call for AppService context.StartService(intent); from weakfulintentservice execute perfectly but AppService cant start In xamarin.android.
You can refer to Started Services, in your Xamarin.Android code where you want to start your AppService, you can code as simply as this:
StartService (new Intent (this, typeof(AppService)));
If you want to start a service with an intent filter, you can refer to this part.
Also you may refer to the case I answered several days ago: Xamarin Android : Change UI TextView text from Service or Receiver.
