libexif | libexif with Android | Android library

I've developped Java application to make some litle web scraping tasks with Selenium. It work fine in my local environment with Windows 10 and both chrome / FireFox last versions with their appropriate driver path configured.

The thing is I need my application to be in a container to deploy it and I've got issues. I've created a Dockerfile based on Alpine, and installed what need to be installed (helped by some posts found on the internet). With the FireFox driver it's working almost fine for the first operations but some do not work the same as they do in my configuration in local and some even crash the client... That's why I've tried with chromium but I've got some issues with a connection to the browser not even working.

I've spent hours already on this and start thinking maybe I'm missing something, am I supposed to do that way by dowloading browsers and driver in my Dockerfile ?

For now I sucpect the versions of FireFox or the geckodriver associated not behaving the same as the one I've got on my machine and I can see the browser when It's working inside the container only logs I've added.

Dockerfile (for FireFox browser try) :

My scenario scheme with negative tests are failing, but when I run locally they pass. According to my BDD the system message for invalid access is Portuguese but I receive it in English. expected: "Login/Senha incorreto" got: "Access Denied: Invalid credentials."

I am trying to create a wrapper around a C library (libexif), so I can use it in Swift for reading metadata from Images.

I am quite new to C and Swift, but I have managed to get a bit of the way, however one problem stumps me.

One of the structs in libexif has a element called **entries which is of type ExifEntry (seen here).

I have understood this to be a way to describe arrays in C with pointers.

However in Swift, this is inferred as UnsafeMutablePointer?>! type, indicating only one element.

I have found a few examples on how to turn arrays in Swift ([String]) to **array in C, but nothing the other way around and I cannot really seem to understand how to solve this.
