I just wanted to try ART of android 4.4 on my emulator. What I did was create an emulator with selecting device as "Nexus 7" and target as "Android 4.4" and RAM "512". Then I started emulator and it loaded. Then I went to Developer Options and selected runtime as ART. After that setting emulator started to reboot and kept on booting screen for a long time(around 1hr) and couldn't finish launching.
Can anybody explain me the reason for this issue.
