Android 4.4.2: "Fail to connect to camera service"

[Cyanoure]

I don't know if this version of android is supported or not.
I have an old tablet (Akai TAB-7800Q) with a custom Android 4.4.2 and I decided to try octo4a if it works on that tablet. This device has a separated barrel jack connector for charging, so I think it could be a good choice for OctoPrint if it runs on it.

The custom Android doesn't recognize my camera and as I see in the logs the app crashes because it can't connect to camera service. It instantly crashes when I start the app.
I'm using octo4a version 2.1.0.
I've seen a similar error in #97 and someone said that it's fixed, but it looks like it's not fixed or the error came back. (or this is different)

I couldn't find the stock Android for this tablet and I don't have a backup, so I'm out of luck.
