At https://sourceforge.net/projects/wp34s/files/doc/ you will find a beginners guide (WP_34S_Beg_Guide.pdf) and a comprehensive manual (Manual_wp_34s_3_1.pdf) The manuals apply in its entirety to this port.

The WP 34S project has an IPhone app but no Android app. Wanting to learn about Android and NDK development, I did this.

I labeled this as a port rather than as an emulator as it is not emulating the CPU of the physical device. The firmware itself originally written in portable C is compiled along with the Android Native Development Kit (NDK).

The code for the interface and modifications to the WP 34S firmware are Free Software and released under the GNU Public License v3, as the WP 34S code itself.

Thanks to Walter Bonin, Paul Dale, Marcus von Cube and the rest of the WP 34S contributors for the excelent calculator.
