android - Using Art instead of Dalvik to compile -

i'm using eclipse , have new project using android version 21 (5.0). want compile using fine art instead of dalvik. have accomplish that?

edit : reason of question have problem:

[2014-11-12 10:30:49 - dex loader] unable execute dex: method id not in [0, 0xffff]: 65536 [2014-11-12 10:30:49 - mamut] conversion dalvik format failed: unable execute dex: method id not in [0, 0xffff]: 65536

i expected doing solve problem:

of particular note suggestion of making minsdkversion 21 dev build - allows generate multi-dex output incrementally in new fine art format, making much faster development iteration cycle (at to the lowest degree on android 5.0 devices).

thanks

that's wrong , should read roughly

of particular note suggestion of using android build tools 21.1 , higher multidex back upwards library - allows utilize multiple dex files in dex format hasn't changed @ all, making unchanged development.

the problem of dex format can't contain more 65536 methods. solution simpliy split output multiple dex files. there 2 problems had in past

the dx tool not capable produce multiple dex files it's complicated utilize multiple dex files on device since devices load 1 dex file , code in other ones has loaded somehow manually.

build tools 21 solve first problem, can generate multiple dex files adding -multi-dex flag compile options.

the multidex back upwards library solves sec problem. tells devices how load additional dex files. , fine art runtime on lollipop , above (4.4 had fine art can't same) capable of using multiple files without beingness told how so.

also relevant official building apps on 65k methods document.
