Launch a script at boot

VIM1 Android
1

Hi there,

Do you know how to launch a script at boot on Android Nougat?

I used to create a userinit.sh script in /data/local on other boards but it doesn’t work for the Khadas VIM.
I’ve also tried to put my script in /etc/init.d but it didn’t work as well.

Peace

Are you a developer? Can you build your rom?
You need to modify the source code and execute the shell script.
What’s the function of your script ‘userinit.sh’?

Hi

Yes I am. My userinit.sh launches an executable from /data/local.

Here is its content:

#!/system/bin/sh
/data/local/myExecutable

I’ve gave the file all permissions.

chmod 0777 /data/local/myExecutable

About how to add support for the script in the path ‘system/etc/init.d/’ , You can follow below method to test by adb command.

$ adb root
$ adb remount
$ adb push userinit.sh /system/etc/init.d/userinit
$ adb shell vi /system/bin/preinstall.sh
$ adb sync 
$ adb reboot

Notice:

  1. The file ‘userinit.sh’ must be renamed as ‘userinit’

  2. Modify the file ‘system/bin/preinstall.sh’

Hiii @Terry

I am creating my own service for VIM3. Will I have to create .te file in sepolicy??
Or these three steps are enough??

I have done it.
Though I had to made few changes apart from those three steps suggested by Terry.

Hi
I also use VIM3.
Does the sepolicy folder need to modify ?
ex : *.te
path : \device\khadas\common\sepolicy

Yes, You have to modify sepolicy folder.
