How to set physical button to run app in android custom rom

I've got new mobile from ebay, Blackview bv6000, which has 3 special physical buttons

1. Camera
2. Sos
3. Ptt

Then i need to assign those buttons to run my app and some functions

I got stock rom from Blackview forum, after i extract system.img file and found

\usr\keylayout\Generic.kl

which contains list of key function that i need

key 212 CAMERA

...

#[AGOLD][2015.04.08]Fengjun merge
key 249 FUNC1
key 250 FUNC2
#[AGOLD]End

The question is how can i assign that key to run my app or function in my app when I'm in home screen or in other app or even the screen is off

Any Physical Difference Between 2015 & 2016 J7 ?

I bought a Sojitec case for my J7 2016 version. Everything fits except the volume button. The case's volume button is higher than the phone's button by 1 or 2 cm.

I tried to stretch it but it doesnt work. Despite this, when I press the decrease part of the button, it increases volume.

Is it possible that theres a physical difference between the 2015 & 2016 versions of the J7?
