Update Check Measure Android application

We need an update to our existing Android 'Drapes Check Measure' app. On the Measure page we need a new field adding below 'Recess to Radiator'. This will be called 'Head Height' and the value will be stored in the FitterItems table. I will create new web service methods to upload and download the data with this new field, as the existing methods will need to remain in place for the current version of the app. You would just need to use the new method names when making the changes. On completion a copy of the source code for the original app and any dependent libraries must be supplied by the Freelancer - your bid should take this into account.
