After announcing that Android L would support 64-bit hardware way back in June, Google has finally released a 64-bit Android L developer preview emulator image. Curiously, though, it's a 64-bit image for 64-bit Intel chips (Atom/Bay Trail) and not ARM. With Nvidia's 64-bit Tegra K1 supposedly just around the corner, but no tools for developers to actually create or prepare 64-bit ARMv8 apps, what exactly is going on?
