Run Script through Android app and prevent killing process

I have a script that is run from an android application via:

Process su = Runtime.getRuntime().exec("su");

DataOutputStream outputStream = new DataOutputStream(su.getOutputStream());

outputStream.writeBytes("sh /system/bin/androidtolinux.sh"+ "\n");
outputStream.flush();

outputStream.writeBytes ("\n\nexit\n");
outputStream.flush();

su.waitFor();

      

        
        
        
      

    

This works great, however part of the script stops zygote with:

setprop ctl.stop media & setprop ctl.stop zygote

      

        
        
        
      

    

After that, the application will be destroyed along with all the processes that it starts, including the process running the script.

SO my question is, how can I run my script through the application, but so that the scripting process is not killed as soon as it is executed setprop ctl.stop media & setprop ctl.stop zygote
