Always I'm getting savedInstanceState values is null.

I have a DrawerLayout with two fragments and one of them has a GoogleMap. At launch the map works as it should. But if i switch to the second fragment and the nswitch back to the first, or if an orientation change happens the map loses its "zoom to my location" button at the upper right corner of the map and it doesn't show my location with the blue dot and the accuracy radius. But I can still shows the map and I can zoom in and out with mu fingers. Am I doing something wrong in my code? How can I fix this?

}
}
Like usual I figured out the answer just right after I posted the question...
In the onDestroyView I added the mMap=null; line...So now the the setUpMapIfNeeded function will run again and instantiate the map again and will be good as new. Hope this helps someone
#Override
public void onDestroyView() {
// TODO Auto-generated method stub
super.onDestroyView();
try{MainActivity.mapFragmentManager.beginTransaction().remove(MainActivity.mapFragmentManager.findFragmentById(R.id.location_map)).commit();
}catch(Exception e){}
mMap = null;
}
I've googled this for quite a while and nothing seems to match my issue. When my app starts the hamburger is fixed (no animation) until I do an orientation change, then it animates in both layouts. I'm using the ActionBarDrawerToggle from the v4 support pack (deprecated, I know). Here's the (fairly standard) code:

// load slide menu items
navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);
// nav icons from resources
navMenuIcons = getResources()
.obtainTypedArray(R.array.nav_drawer_icons);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.list_slidermenu);

Can anyone see where I've gone wrong and how to get the hamburger to animate all the time? Thanks!
I am using navigation drawer from this tutorial http://www.androidhive.info/2013/11/android-sliding-menu-using-navigation-drawer/

Add this condition
if(position == 0) {
Intent i1 = new Intent(MainActivity.this,Activity2.class);
startActivity(i1);
}
else {

}
at,
displayView(position);
It will work but sliding menu will not be appere in second activity you have to again add it.

You may use: (to open drawer on left)
DrawerLayout.openDrawer(Gravity.LEFT);
Add next sniplet atter initialisation of drawer
for opening drawer:
if (mDrawerLayout.isDrawerOpen(Gravity.LEFT))
mDrawerLayout.openDrawer(Gravity.LEFT) //for left drawer
for closing drawer:
if (!mDrawerLayout.isDrawerOpen(Gravity.LEFT))
mDrawerLayout.closeDrawer(Gravity.LEFT) //for left drawer
