Delay in Broadcastreceiver call

I am calling BroadcastReceiver on Some Time Input, but I am getting 10-15 seconds delay in onReceive of Broadcast.

Activity.class

Intent intent = new Intent(DashboardActivity.this, TimeAlarm.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(DashboardActivity.this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
    alarmManager.set(AlarmManager.RTC_WAKEUP, timeinMillis, pendingIntent);

TimeAlarm.class

public class TimeAlarm extends BroadcastReceiver {

@Override
public void onReceive(final Context context, Intent intent) {

    Debug.e("RECEIVER_TIME", "ALARM_READY");

Note: Beginning with API 19 (KITKAT) alarm delivery is inexact: the OS will shift alarms in order to minimize wakeups and battery use. There are new APIs to support applications which need strict delivery guarantees; see setWindow(int, long, long, PendingIntent) and setExact(int, long, PendingIntent). Applications whose targetSdkVersion is earlier than API 19 will continue to see the previous behavior in which all alarms are delivered exactly when requested. https://developer.android.com/reference/android/app/AlarmManager.html

If it is really important that there is no delay, use setExact for API 19,20 and 21 and use setExactAndAllowWhileIdle for API 23 and 24.
