Sample service for testing
This is a sample service that can be used for testing init.
Design
The service includes a .rc file that allows starting it from init.
service test_service /system/bin/test_service CapAmb 0000000000003000
class main
user system
group system
capabilities NET_ADMIN NET_RAW
disabled
oneshot
The service accepts any even number of arguments on the command line
(i.e. any number of pairs of arguments.)
It will attempt to find the first element of each pair of arguments in
/proc/self/status, and attempt to exactly match the second element of the pair
to the relevant line of proc/self/status.
Example
In the above case, the service will look for lines containing CapAmb:
cat /proc/self/status
...
CapAmb: 0000000000003000
And then attempt to exactly match the token after :, 0000000000003000,
with the command-line argument.
If they match, the service exits successfully. If not, the service will exit
with an error.
Usage
mmma -j <jobs> system/core/init/testservice
adb root
adb remount
adb sync
adb reboot
adb root
adb shell start test_service
adb logcat -b all -d | grep test_service
Look for an exit status of 0.
