Android L

Android app developers can now download a new 64-bit Android L emulator image from Google, but there's a big catch: It will only work on x86 Intel-based processors.

The new emulator will allow app developers to optimize their software for 64-bit versions of Android L. In a Google+ post, the company said app creators will be able to access a larger amount of addressable memory space with 64-bit support, along with a bigger number of registers and new instruction sets. While apps built using Java will automatically access all those cool features, Google says apps made using the Android NDK will take some additional optimization to achieve full 64-bit support.

Of course, the vast majority of Android devices use ARM-based processors but there's no word on when a 64-bit emulator will be released for those kinds of CPUs.
