Answer 1

so if the onSaveInstance was Called

you can declare a global variable for your

 int pos=0; 

after onSaveInstance() gets called, method below is called:

@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
pos=savedInstanceState.getInt("tab", 0);    

}

so in your onCreate() function replace the condition from this:

if (savedInstanceState != null) {
    actionBar.setSelectedNavigationItem(savedInstanceState.getInt("tab", 0));
}

to this:

if(pos>0){
actionBar.setSelectedNavigationItem(pos);
}
