java - How to add the environment variables to the android Runtime.getRuntime().exec command? -

there's issue when run android runtime.getruntime().exec method.

i have native binary file run on android , start java method runtime.getruntime().exec. running native binary file requires addition of environment variable. execute command:

envsetcmd = {"sh", "-c", "export ld_library_path="+excbinfilepath+":$ld_library_path"}.

it doesn't work when check environment variable command: sh, -c, echo $ld_library_path.

i think reason when set environment variables start shell , when check command "echo" shell started. environment variables didn't work in shell check it.

i think there 2 ways solve issue. 1 running 2 commands in 1 shell. tried use command:

{"sh", "-c", "export ld_library_path="+excbinfilepath+":$ld_library_path", "-c", "echo $ld_library_path"}. 

unfortunately illegal. other add environment variables android user startup files. tried echo $path, , see /system/bin/ , other path loaded @ startup of android.

so think there must file ~/.bashrc in linux set users' environment.

any 1 give me clues ways listed above? way, shouldn't root phone!

try execute whatever need execute env:

{"env", "ld_library_path="+excbinfilepath, "yourcmd"}
