Android getIntent() returns same intent in onResume() each time. how to clear int field in a bundle?

I am working on app that uses getIntent() to read bundled information. I would like to set one of the bundle fields to null, so that on subsequent resumes a modified intent is received, but I keep getting the same intent back from getIntent(). I notice that after the back key is pressed than a new intent is produced, but not otherwise.

intent.getExtras().getInt("FLAG_FIELD") returns 1
intent.getExtras().setString("FLAG_FIELD", null);

but when the Activity resumes again getInt() still returns a value instead of null. Not sure than how to clear a Int field in a bundle.

Update just tried:

intent.getExtras().putInt("FLAG_FIELD, -1);

This also does not work. Looks like intent from getIntent() cannot be changed.

Update: onResume() gets called in the debugger 3 times in a row before the activity becomes visible? So even if I set a flag here it seems that its hard to change state because I cannot tell which resume() call is the last one before an actual display.

You can override onNewIntent() and change the extras there. Here is the documentation for that. After this method, your onResume() will be called which I think is what you are after
