One might expect that Google is going to give the stock Android client interface a visual upgrade.
Records and screenshots have been discovered by Android Police which uncover the updated icons appearing in the Android scene soon enough. Allegedly, the new bearing in Android iconography is named Moonshine.
It is like the style utilized by Google for its online administrations, and uses icons meant to compliment the user. It must be noted that the leaked icons may not be the final ones as everything is liable to change prior to this information being revealed as one that is official.
Subtle elements on the introduction of the new Android icons are yet to be uncovered. It is expected though; the Android users will be pleasantly surprised with the official information regarding the icons at the Google I\O developer conference.
