Raised when the Corona runtime has been suspended which pauses all rendering, audio, timers and other Corona related operations.

This is typically raised when the end-user navigates to another app or when the power button has been pressed.

Raised just before the Corona runtime environment is about to be terminated.

This typically happens when the end-user backs out of the app, the Corona XAML control has been unloaded from the page, or when the runtime's Terminate() method has been called.
