OS X: just wanted to start my 3 weeks old Android Studio to update and realized it wants Java 6 from Apple. Is this normal? I have Java 8 installed here.
Apple's Java 6 uses Quartz for text rendering, which looks really good and is pretty fast. Oracle's Java 7/8 do text rendering in software, which is slow and looks extremely bad on OS X compared to, well, everything else.
It only uses Java 6 for the IDE, Gradle and the other Android tools should still run with your regular modern Java 8 if I'm not mistaken.
It's not ideal, but after comparing the two I found Java 6 + Quartz by far the best solution for now...
Did you try the openjdk that is bundled with intellij idea eap builds? It is Java 1.8 with quartz font rendering. I use this version since December last year to run AS without any problems.
