Nice! is this to fix: https://github.com/emoncms/AndroidApp/issues/35 ?

How do you make this error message appear? If I create a new page the feeds are already populated so I don't see the error message

It fixes #35 , but it is the first time I use "android studio" and that compile an app !! I do not guarantee anything :) to recreate the error:

• create a new page
• changing the feed in anything but no AUTO
• displays the page
• go to change and select the auto feed on each
• back to Display the error is show !!
