Maybe the reconnect options are specific to the device. I can't find any pre-build android ffmpeg 4.x binaries either.
Anyway, you need to turn them off so they don't appear in the jobs file.
This should not be in the cmd line:
'-reconnect_at_eof', '1', '-reconnect_streamed', '1', '-reconnect_delay_max'

Try changing the m3u and xml so that you have a simple channel name and program title.
The ones in the tests folder were designed to test awkward punctuation and unicode characters.
Call the channel "test" and the program title "test" so the filename is just ascii.
Make sure the tvg-id is test and the "channel id" is test too to be safe.

Remember to turn the ffmpeg debug setting off again that writes the stdout/stderr files to actually record something. 

Finally i it works! 
As you said, the problem were the reconnect options.
However, turning it off in the settings does not works, it still generates the options in the job py file.
I made it working by commenting the corrisponding lines in the main.py.
I also had to download a newer version of ffmpeg from here
Thank you primaeval for your support! 

Thanks.
version 0.0.124 should fix the reconnect options.

Are you running the linux build of ffmpeg on spmc on android 4.4?
