SavedInstanceState is always null in fragment

All the problem was in that I don't declare android:id for the fragment in XML. Android needs ID or TAG to recognize stored fragment and reproduce all elements in it. So guys, remember - every instance of fragment needs unique id or tag!

Also, when setRetainInstance(true) is declared then bundle should always return null.

I had a similar problem where I was always getting savedInstanceState as null inspite of supplying the bundle to the Fragment.

The only solution that worked for me was to do

myFragment.setArguments(bundle) 

with my bundle from the Activity and do a

Bundle bundle = this.getArguments();

in onCreateView of the fragment.

Hope this helps someone else.

For Fragment :-

use this for save state of fragment on orientation.

onCreate(Bundle save)
{
   super.onCreate(save);
   setRetainInstance(true);
}

See this tutorial :- http://techbandhu.wordpress.com/2013/07/02/android-headless-fragment/

For Activity:-

When you start your application, in onCreate, your bundle object is null, so you have to put a check like below and when you rotate your screen then onSaveInstance is called and your bundle object is initialized

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_game);

    if (savedInstanceState != null) {
         boolean t = outState.getBoolean("restore"); 
         int s = outState.getInt("nAndroids");
    }
}

First you should put your data, then call super.onSaveInstanceState(outState);

public void onSaveInstanceState(Bundle outState) {

    outState.putBoolean("restore", true);
    outState.putInt("nAndroids", 2);
    super.onSaveInstanceState(outState);
}

And be sure that activity has not nohistory property in AndroidManifest.xml or set it to false.

        <activity
        android:noHistory="false">
