I created a custom .rc file (/etc/init/nerding.rc) which initializes a custom "service" I made (/system/bin/listen) at boot, but after an hour or so my Android gets sluggish, isn't very responsive and when I check the dmesg, my nerding thing has failed and restarted thousands and thousands of times. Like once every 3 seconds.
The idea behind my file is that it listens for specific volume key and touchscreen taps whereupon it then hides or unhides some specific apps. Think 'Apex,' but with less evidence. I'll post the code and see if anyone has any suggestions/ideas. Please keep in mind that I only have JavaScript experience, so my BASH (or whatever Android's version is called) coding is haphazard at best. I am guessing my issue is because I'm not running my service as a 'oneshot,' but if I don't then the listen tool only listens once and quits. It needs to run every...2-5 seconds?

I'm sure this could be more succinct and efficient, but everytime I tried to combine some steps I broke it!
The error I constantly get in dmesg is (with a higher pid each time):
[ 277.585578] (3)[1:init]init: Service 'nerding' (pid 4073) exited with status 0
[ 277.585621] (3)[1:init]init: Sending signal 9 to service 'nerding' (pid 4073) process group...

Please, any suggestions, revisions, or criticisms are greatly appreciated.
