[libbluray-devel] BD-J possible on android?

[Vitor Dall'Acqua]

I've been following the development of Corelec and they managed to find a
ARM based solution for JAVA.

It's a Kodi addon named JAVA JRE Zulu.
I know this mailing list is mostly aimed to VLC but I believe this could
benefit both Kodi and VLC.

Here's the addon:
https://balbes150.libreelec.tv/addons/9.80.3/arm/tools.jre.zulu/

Here's the source for it:
https://github.com/LibreELEC/LibreELEC.tv/tree/master/packages/addons/tools/jre.zulu

Now the problem is, most Android boxes are not rooted and I can't find a
way to set $JAVA_HOME path without rooting.
Tried Termux with the Nvidia Shield but the path is used only by Termux.

Any ideas how to set it would be appreciated and hope this is of any use
for future VLC development on ARM based plataforms.
