The difference between Android Dalvik and art

The Dalvik mode is like a folding bike, which is assembled before each ride to get on the road. The art model is a bicycle that has been installed and can be taken out of the car directly. So art mode is certainly better than dalvik in efficiency.

From the above table, we can plainly see that the new Art mode has the features of small RAM memory, better smoothness and more power saving.

1:art mode is the abbreviation for Android runtime. In the art virtual machine environment, Android only compiles the program once, that is, when the program is installed. When you install an app, the art virtual machine translates the program's Java language into a machine language that works for Android, and it's a compile-time lifetime benefit. This is exempt from each run of the program, the need to recompile the trouble, the system's operational efficiency has been greatly improved.

2:dalvik is a Java virtual machine designed by Google to be used on Android platforms. Dalvik virtual Machine is one of the core components of Android mobile device platform developed by Google and other manufacturers. It can support the operation of a Java application that has been converted to. Dex (that is, Dalvik executable) format, which is a compression format designed for Dalvik and is suitable for systems with limited memory and processor speed. Dalvik is optimized to allow instances of multiple virtual machines to run concurrently in limited memory, and [1] each Dalvik application executes as a standalone Linux process. A standalone process can prevent all programs from shutting down when the virtual machine crashes.
