It is the out of memory killer.
You can SSH to your device, run command devel-su dmesg -w | egrep "lowmemorykiller|oom_reaper|^ {19}.*|Out of memory" and try to restart the Android App support from your phone again - you can do this multiple times. Look through the logs and see if you find something that starts with lowmemorykiller or oom_reaper.
You may post the logs here as well. They shouldn’t contain anything sensitive, but please read them through carefully before posting.
