Do i have to factory rest the phone after converting to ART.
Another thing, when i tried to go back to delvic and install what's app it showed the same error as on ART
root your phone. open root explorer or adb shell
if root explorer:
go to folder data, then go to folder data again(yes there are 2 folder datas, one within another)
delete any folder with whatsapp on the name (i think its com.whatsapp.something)
if adb shell:
type su and grant permissions on the phone.
type cd data/data
(it will show all files/folders)
get the folder with whatsapp name on it
rm com.whatsapp.something/* (the name is different, but it must have whatsapp on the name)
exit (again, because the 1st one just leave out of root mode)
reboot phone and try to install whatsapp again(dosent matter - art or dalvik, it must work).
