NookCalc is a basic, four function calculator designed from the ground up for the Nook Simple Touch. It is optimized for the e-ink display. I wrote this app. The top right page button acts as a dedicated clear button, in addition to the on screen clear button and clear option in the menu.

That looks nice, but 840 kB is way too big an .apk file for what this does.
It should be somewhere in the neighborhood of 10-20 kB.

You have included android.support.v4 and android.support.v7 when they are not used in the least.
You can delete those from your project.

Nice! It's good to see apps written for the nook.
The calculator looks nice and the e-ink optimization is great,
however, since I don't have anything to calculate just now I just did a bit of stress testing to find that:
a) there seems to be an int overflow on really large nubers, it either crashes or warps to negative.
b) I'm not sure what pressing '=' repeatedly is supposed to do (if anything at all) as it gives weird and inconsistent results.
c) it crashes on division by zero (I HAD to try that )
d) Also, to have a useful division function you really need to use floating point numbers.

It's a nice project, but needs some working on before being a useful calculator

Thanks for the feedback guys, I appreciate it. Renate NST I removed the android.support.v7 and it significantly reduced the size of the apk from 837KB to 60.4KB, a 776.6KB difference. I didn't see android.support.v4 in my project. I didn't add any support libraries myself, Android Studio seems to put the support library in new projects and there doesn't seem to be a way to make a new project without the support library.
