https://github.com/bravobit/FFmpeg-Android just 

FFmpeg.execute(" command ");

I use filter-complex, but process was killed with no error

is this clue error message ? 

"`[out_0_0 @ 000002092867e200] 100 buffers queued in out_0_0, something may be wrong.`"

Can you tell me how to fix it? below is my command I think syntax is ok, but sementics is wrong.

-y -i /storage/emulated/0/Download/error_movie.mp4 -filter_complex "

[0:v]trim=start=35.400:duration=30.300,setpts=PTS-STARTPTS[v3]; 
[0:v]trim=start=20.900:duration=14.500,setpts=PTS-STARTPTS[v4];

when you are working with FFMPEG its a good idea to install it on your OS in order to make sure that your commands are correct

in your case the problem is in your command string

[0:a]atrim=start=0:duration=20.900,setpts=PTS-STARTPTS[a2];

should be :

[0:a]atrim=start=0:duration=20.900,asetpts=PTS-STARTPTS[a2];

you have to use asetpts when you are using atrim filter
