Difference between DVM( Dalvik Virtual Machine) and ART
What Is A Runtime Environment?
Why Use A Virtual Machine At All?
So, What’s Dalvik, And What’s Wrong With It?
What Is ART & How Does It Improve Things?
Dalvik Vs. ART – Comparison
|Uses Just-In-Time (JIT) approach, which results in lower storage space consumption but longer app load times||Uses Ahead-Of-Time (AOT) approach, which compiles apps when they’re installed, resulting in faster load times and lower processor usage|
|Cache builds up over time, so boot times are faster||Cache is built at first boot, hence rebooting device takes significantly longer|
|Works better for lower internal storage devices as space occupied is lesser||Consumes much more internal storage space since it stores compiled apps in addition to the APKs|
|Is stable and time tested – VM of choice for app developers||Is highly experimental and new – not a lot of support from app developers yet|
