Android - Is the intent preserved during activity recreation?

Question

I am building an android application, and would like to ask if the intent that started an activity (which is reachable via the getIntent () method) is saved / preserved during activity recreation such as a device orientation, or simply the fact that android can erase the application state if it is in the background and rebuild it (if it is low on memory) ?

This is a quick example that illustrates the question :

The application launches activity A. Then the user clicks on a button that starts a new activity B. Activity A has sent to activity B a string X with the value Hello via the intent (using the putExtra method).

In activity B, I can retrieve the content of string X by retrieving the intent (via the getIntent () method) and then retrieving the string content (via the getStringExtra method).

Will I still be able to retrieve the extra string from intent, or even the intent itself if the activity is recreated due to device rotation, ... ?

Or should I save the extra string in the onSaveInstanceState method ?

I have tried the device rotation scenario, and the intent (along with the extra string) are always accessible.

Yes. You will have the same Intent (or, at least, a copy of the Intent) after the configuration change as you had before the configuration change.
