So I just installed android studio for PlayOnLinux and it was fine.  When I try to start it, it is looking for JAVA_HOME environmental variable to be set to the jdk. 
I have the jdk installed in my virtual windows directory as well as on linux. How do I set an environmental variable in PlayOnLinux?
I tried adding export JAVA_HOME=/jdk-installation  to .bash.sh  and /home/myUser/playonlinux-bash.sh but neither did anything.  Is it somewhere in the GUI?
