Numbers and letters in java script

I'm currently editing an app that my friend paid to be made. He's asked me to edit the portal URL because he has changed his server address and can't get in touch with the guy who made the app so I've been looking for the portal URL so I can change it for him but I can't find it anywhere. Tried searching his port, url and the server IP address but nothing. I'm thinking maybe its hardcoded or encoded some how but when I've been looking in the .xml files in the apk I keep coming accross this type of coding

                    android:id="@7F070011"
        android:layout_width="0.0dip"
        android:layout_height="0.0dip"
        android:hint="@7F0A00EC"
        android:ems="10"
        android:inputType="0x00000011"

Anyone know how to convert it to text so I can read what it says or does anyone have any ideas what theh mean?
