Question

In the Android Activity lifecycle, when Activity.onCreate() is called after resuming (IE. not when activity created initially or in response to screen rotation) would this code return a valid (non-null) Bundle?

public void onCreate(Bundle savedInstanceState) {
    Bundle b = this.getIntent().getExtras();
    // is b == null? (when activity is resumed)
}

I am trying to reproduce a problem that occurs when the application has not been used for a long period – when the user returns, the application crashes.

Answer 1

okay, so when Android kills my app and the user navigates back –
onCreate() is fired with a >new< Activity, and the original Intent
along with it’s associated Extras is gone; or do the Extras get
attached to the new Intent by Android?

I was wondering the same thing and tested this quickly in my application.

It turns out intent extras are available when an activity is re-created after your application got killed.
