Android: onSaveInstanceState not being called from activity

Question

I have an Activity A which calls Activity B. In Activity B, when i click on a button, finish() is called, which in turn calls onDestroy() of Activity B and returns to activity A.

According to android documentation, Before onDestroy is called, onSaveInstanceState(Bundle bundle) will be called, where i do the following.

@Override
    public void onSaveInstanceState(Bundle outState) {

        super.onSaveInstanceState(outState);
        System.out.println("Saving webview state");
        Log.d(TAG, "In onsave");
        wv.saveState(outState);

    }

and the next time Activity B is started from Activity A,

in the oncreate(), i do the following:

onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);

if(savedInstanceState != null){
//restore webview
}else {
// code
}
}

However, before calling onDestroy in Activity B, The onSaveInstanceState method is never called. any help on this will be greatly appreciated.

EDIT: if this is not possible. Please let me know if there is a way to store webview state

Answer 1

I had a similar situation. It was clearly a dev bug. I've overridden the wrong method:

public void onSaveInstanceState(Bundle outState, 
                                PersistableBundle outPersistentState)

Instead a correct one:

protected void onSaveInstanceState(Bundle outState)
