Recreate an activity and also pass arguments

Question

I have an activity that listens to preference changes and reloads the app. I am using recreate() to do that. But I don't know how to pass in arguments through that, so I have resorted to manual activity reloading.

Intent intent = getIntent();
finish();
// add in the arguments as Extras to the intent
startActivity(intent);

This has the behaviour I want, but the recreating of the activity isn't smooth for the user as they will see the activity being killed and the same activity relaunching. I want the user to not be aware that the activity was relaunched. So, my question is can I use the method recreate() and still pass arguments through it.

Answer 1

You can set the data on the activity's intent before calling recreate

        getIntent().putExtra("RECREATE_DATA", "Some Data");
        recreate()

since when you recreate the activity the same activity instance is used, the data in the intent will still be there after recreate.
