their is only two silly problem as I found .. You just change this fragment

                <fragment
                android:id="@+id/popupmapview"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:layout_margin="10dp"
                class="com.google.android.gms.maps.SupportMapFragment" />

to this..

                <fragment
                android:id="@+id/popupmapview"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:layout_margin="10dp"
                class="com.google.android.gms.maps.MapFragment" />

and change a line in method [initiatePopupWindow]

map= ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.popupmapview)).getMap(); 

to this..

map = ((MapFragment) getFragmentManager().findFragmentById(R.id.popupmapview)).getMap();
