Sparky Linux is based on Debian testing.
It seems that all openjdk-7 packages have been removed from the Debian packages sources.
So the only openjdk available for Sparky is the version "8".
Among other activities, I build Android custom ROMs.
But to build those, except if I want to build the not even released Android "N", I need Openjdk-7.
Unfortunately, it seems there is no way for me to install that one (those nasty dependencies are never fullfilled !).
So I had to install another distro to be able to use my Linux for what it's meant to do :-(
I must that I hardly regret this, as Sparky was really nice !
So if anyone knows how to install openjdk-7-jdk on Sparky 4.3, I'll take it's advice to put it into use again :-)
Thanks a lot...
