if you know how to make it work, then you shouldn't be asking. There's an obvious reason of why Google left it disabled by default. You also should know that you shouldn't be complaining about an experimental feature.
Dude, I'm not even complaining. OK, tell me how can you make ART work? Yeah it's as simple as:
1. installing 4.4 ROM
2. flashing ODEXED GAPPS
3. activating ART
how hard is that?
With my Nexus 4 it works great without any issues. I know there are many incompatible apps but I don't care. I would just uninstall those incompatible apps and I'm fine. I don't need Whatsapp, I don't need Titanium Backup.
The thing here is that, if I did every step properly and exhausted remedies, then the problem might be with the ROM itself.
I'm raising these questions so that Daniel would know that there is a problem with this part of his ROM and so that might be able to do something about it.
Again, I am not complaining. I am seeking help for a possible bug in Daniel's ROM.
You're so illogical.
