Apps some basic questions about an android app

I am using this electronic gadget from Atmel called SAMW25 and it comes with an android app which takes the wifi SSID and password and passes it on to the SAM25 module.
I am trying to understand how this app would be working and can I write my own android app to communicate with the SAMW25 module ? using TCP/IP sockets?
 
attaching the .apk file , can someone reverse engineer it and see what it is doing ?
this is a demo app from Atmel and is not a commercial product.

I think it's very unlikely someone will spend the time doing this for you, and with the greatest of respect, you will learn far more from it, if you try to reverse engineer it yourself - particularly if your intention is to understand what it does, and communicate with it.
 
here is the error I am getting .. can someone tell me how to fix it ?

ok issue was fixed by using the command "apktool b avrforiot" without the ".apk" extension

C:\android>apktool b avrforiot
I: Using Apktool 2.0.3
I: Checking whether sources has changed...
I: Smaling smali folder into classes.dex...
