What is the current behavior?

If a Dialog is currently being shown, and the app is sent to the background where the Activity is then destroyed, when the app is brought to the foreground the app will crash.

This is because when the activity is destroyed, the dialog is torn down, but this happens after state is saved and it crashes when the dialog is being restored.

( Easy to test by turning on the Don't keep activities developer option. )

What is the new behavior?

The change is to cancel the dialog creation if being restored in a state where the creation of the dialog will crash.
