I am working on alarms and making an app for task reminder. I am showing notification at scheduled time by user. But when alarm rings , notification appears . Then I switched off my phone , and again when I switched , on the notification get disappeared(doesnt show the notification). while in the case of SMS notifiaction(default android implementation) it does not get disappeared until we drag the notification.

I want the same as like sms notification. What should I do?

Notifications are not persistent across device boots. If they reappear for certain apps, it's because the app is starting on boot and re-creating them.

You should define a receiver that determines if the notification should be present and creates it if necessary, and start this receiver on device boot.

Set its intent filter for,

android.intent.action.BOOT_COMPLETED

and use permission,

android.permission.RECEIVE_BOOT_COMPLETED

and make sure your receiver has permission,

android.permission.RECEIVE_BOOT_COMPLETED

Like this,

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
...
<receiver ... android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
  <intent-filter>
    <action android:name="android.intent.action.BOOT_COMPLETED"/>
   </intent-filter>
</receiver>
