Question by R2D2 · Nov 14, 2010 at 08:57 AM · android

android "application quit"

I would like my game to absolutly quit when i hit the hard button "home" on my android device.

function endgame () { if (Input.GetButton ("home")) { Application.Quit(); } }

this code will stop game and take me to my device home screen but the game is still running in the background of my device in a paused state (good for a phone call or a required pause) but it's still processing. How can i force a complete quit of the game on android?

As you say HOME is a 'hard' button; actually so hard that it can't be intercepted. Instead the application will be sent to the background with a OnApplicationPause() call. Theoretically you could add a call to Application.Quit() in OnApplicationPause() but thats really not recommended as it will cause the application to quit if you receive a phone call etc.

Applications should be paused when pressing HOME (or pressing the power button, or receiving a phone call); this is part of the Android OS architecture. A paused application doesn't actually consume that much resources (in terms of CPU / memory) as all graphics resources (created textures, meshes etc) are flushed when the application is sent to the background, and the player loop is also not updated when the application is paused.
