Greetings!

So, the problem here is that our app isn't working, even though it was two days ago, initializing the barcode scanner correctly and stuff.

To verify whether it was a problem with the app itself, I installed the demo app (barcodescanner1) to understand the library code, and the demo isn't working either.

The device: TC510K, with android 6.0.1.

The only solution I saw here in the discussions so far was to add com.symbol.edmk.jar manually to the project, but I don't know if it makes sense in my case since:

    I'm already downloading the required dependency from jcenter (according to gradle, both my app and the demo are using com.symbol:emdk:7.3.14).
    The demo worked fine without having to do anything to it, and the dependency wasn't added in it manually as the solutions in the forum ask to do,
    Even if I have to actually add the jar, I can't seem to find it anywhere (aparently it comes within an installer specifically made for either windows or macos, and here at work I haven't found anybody with those OS as of yet).

I even reset the device to factory settings in case I configured something wrong on the device by accident, but it didn't help either.

Most likely I'm missing something, but I don't know what could it be, like, everything was working fine two days ago.

Anything that might help will be greatly appreciated.

Oh, and I forgot the error shown by logcat when trying to run the apps:
