[ CONSULTA ] Problema con Variables

[JuanSantini_]

Hola que tal amigos, este es mi primer post, ya tengo varios meses dandome la vuelta por estos foros.
En estos momentos ando en proyecto y tengo un problema con mi app..

En un intent tengo un EditText donde tengo la variable (solo para checar), de ese intent al sumir un boton me manda a Google Maps, donde me da la ubicación en latitud y longitud, esas variables las quiero guardar y regresar al intent anterior y refrescar el edittext ya con la información en las variables ( es un Double, ya saben -90.009090990 ).

El caso es que siempre regresa vacío, o al menos no se refresca la información.

Es difícil por que siempre trabaje con Netbeans, y me guiaba con los Watches, pero con Eclipse no tengo Watches, no se donde estaría el error.

Si me pudieran ayudar muchas gracias!

Si gustas permite que vea tu clase y vemos en donde anda mal el código, quedo a tus ordenes

Esta es la class donde abro el Google Maps, con Geolocalización determino la latitud y la longitud y la guardo en la variable.
