Google I/O announced next major update of Android at developer conference in 2014. (Code Name: Android L). Updated version will improve the notification system, updated user interface and new battery saving mode. The most important thing would be to use ART runtime, which will increase application performance double.
Many people think to get ART runtime you need Android L. But the concept is wrong. Google first launched ART technology in 2013. Nexus 5 is the first device where ART runtime have used which operating system was kitkat 4.4. But it is right that every Android 4.4 OS device in market doesn’t support ART. HTC One M8, Samsung Galaxy S5, Moto X, Moto G, Nexus 5, and Nexus 7 are Support ART. Some of the other smart phones such as Korean model of LG G2 can active ART.
How do you active
Go to the Settings menu on your Android KitKat -based Smart phones. From there, select About Phone then tap on continuously Build Number 7 times. If you can tap successfully you will see your device’s developer option has activated which will allow you to access more advanced settings.
Now select developer option from setting menu and select runtime from the down. By selecting ART your device will request to restart. If no request come then restart your phone manually. After reboot, your device will begin to optimize apps for the new runtime. Wait for a while to end the process. After that you will have a new experience from your smart phone.
Warning: Very few applications do not support ART runtime. If it is very necessary to run the applications enable Dalvik mode in the same manner.
