Android 4.4 KitKat: Activate runtime environment (ART)

Since Android 4.4 KitKat you can activate the new runtime environment ART. We'll show you how.

Since the new runtime environment is not yet fully developed, it is still slightly hidden by Android:

Open the "Settings" on your Android smartphone and scroll down a little to the point "About the phone".
At the bottom you will find the entry "Build number". Tap the field seven times to access the developer options.
Go back one step and select the "developer options" that appear.
Press "Set runtime" and then select "Use ART". Make sure once again that the developer options in the top right of the screen are really set to "On".
After a restart, the system is updated and all apps are installed again. Please note that the apps under ART require a little more storage space.

In this practical tip, we'll tell you what lies behind the immersive fashion of Android KitKat 4.4.
