# What is the call back method for killing the application instance?

Hi Guys,\
In my [application](https://www.mindstick.com/articles/12824/calculator-application-in-android) I want to get notified when the [instance](https://www.mindstick.com/forum/155658/testing-connection-to-cloud-sql-instance-with-a-mysql-client-from-vm-instance) of the application is deleted.\
Even though I can easily get what I am asking simply by googling, I can't find anything [useful](https://www.mindstick.com/articles/12694/how-dolomite-mineral-is-useful-in-human-life) to me. May be the synonym i'm using deleting the app instance (deleting the app from the list shown at the bottom of the [screen](https://www.mindstick.com/forum/33644/loading-screen-during-ajax-call) when double-clicking the [home](https://www.mindstick.com/articles/126322/how-to-keep-your-home-safe-while-traveling) [button](https://www.mindstick.com/articles/63/how-to-add-button-in-datagridview-in-csharp-dot-net) in **iPad** and I'm looking for the **UIAppdelegate** [method called](https://www.mindstick.com/interview/2613/when-does-onresume-method-called) in [response](https://www.mindstick.com/forum/12719/how-to-make-response-write-display-special-character-like-lt-gt) to that [action](https://www.mindstick.com/forum/155752/what-is-action-result-with-its-types)).\
Is there a way of knowing this?Your help is a great appreciated.

Hi Ezra,\
This is when your app gets killed, either by the user (removing from the task bar) or by the system, to reclaim memory. There's no callback for it. You never get informed that it's going to happen or has happened.\
I hope it helpful for you.\
