this might help you,Instead of passing the string through intent use static variable as,
your passing class
class EvacRouteTableActivity extends TabActivity{
public static String routeName="";
/**** write your code here****/
/****change the value of routeName string as per your desire****/
}
your receiving class,
class MapViewActivity extends Activity{
/**** write your code here****/
//access routeName string as below
String recieved_string= EvacRouteTableActivity.routeName;
}
please let me know if you have any trouble regarding this.
