Issue in creating apk for my file

I was trying to make an app, with something like 5-6 screens, but the app is not giving my latest count on screens. Its only giving me the first 3 screens, every time I try to build an apk. Please help in this.

which is it 5 or 6 ? If you do not know, how do you know that the apk is not built correctly, e.g that you actually only have three screens.

Quickest route to a solution is to provide your aia project here so someone can take a look.
