Very soon will release the final version of the new mobile operating system Android L, which will be supported by 64-bit processors. Many manufacturers are ready and pre-released new units with these chips.
Today, Google has introduced a 64-bit emulator Android NDK, which helps developers to test how their applications will work in conjunction with the new system and, if necessary, to optimize.It is worth noting that not everyone will have to make changes to their programs as Java-code is automatically adapted to the 64-bit environment and gets increased access to the memory and the registers.
Google also warns that some applications may not work in the emulator, and the performance gains will be noticeable only in the resource-intensive applications, and "heavy" games. Download emulator for 32-bit and 64-bit versions of Windows, Mac OS X and Linux on the official site for developers.
