Force My Activity To Call The onSavedInstance State

Question

I have an android application in which I use two themes. On theme change I need to recreate all the activities and Fragments inside that to be recreated.

The same way our application get recreated using saved instnce state.

Is there any way I can force my Activity to call the saved instance state ? IF it is possible how I can do that ? If not why ? Is there any alternative to Achieve this ?

My current code looks like below.

public static final void restartActivity(final FragmentActivity activity){
    activity.finish();
    activity.startActivity(new Intent(activity, activity.getClass()));
}

The issue with this is the fragment back stack is not getting recreated. Any help would be greatly appreciated.

Answer 1

Your state is not saved because you're creating a new instance of Activity . As a solution, you can pass your state to this new instance as Intent extras and restore state in onCreate from those extras.
