Android and iOS closing app?

[GGamesStudio]

I am developing an app for Android and iOS and when I press the home button on my Android phone the game's thread is still running in the background.

The music keeps on going.

How can I detect when the user exits the app in order to stop the music or terminate the app's thread?

the event class has an activate and a deactivate events you can use.

On iOS you add a UIApplicationExitsOnSuspend key to your app xml file like so:

<InfoAdditions>

      <![CDATA[<key>UIDeviceFamily</key><array><string>2</string></array><key>UIApplicationExitsOnSuspend</key><true/>]]>

    </InfoAdditions>

on Android it's a different story. See this:
