Its source code was made available on November 3, 2014. One of the most prominent changes in the Lollipop release is a redesigned user interface built around a design language known as "Material design". Other changes include improvements to the notifications, which can be accessed from the lockscreen and displayed within applications as top-of-the-screen banners. Google also made internal changes to the platform, with the Android Runtime (ART) officially replacing Dalvik for improved application performance, and with changes intended to improve and optimize battery usage. , statistics issued by Google indicate that 12.4% of all Android devices accessing Google Play run Lollipop. Lollipop is succeeded by Android Marshmallow (version 6.0), which was released in October 2015. == Development == Android 5.0 was first unveiled under the codename "Android L" on June 25, 2014 during a keynote presentation at the Google I/O developers' conference. Alongside Lollipop, the presentation focused on a number of new Android-oriented platforms and technologies, including Android TV, in-car platform Android Auto, wearable computing platform Android Wear, and health tracking platform Google Fit.〔(【引用サイトリンク】url=http://www.pcworld.com/article/2367746/from-android-l-to-google-fit-all-the-announcements-from-google-i/from-android-l-to-google-fit-all-t.html )〕 Part of the presentation was dedicated to a new cross-platform design language referred to as "material design". Expanding upon the "card" motifs first seen in Google Now, it is a design with increased use of grid-based layouts, responsive animations and transitions, padding, and depth effects such as lighting and shadows. Designer Matías Duarte explained that "unlike real paper, our digital material can expand and reform intelligently. Material has physical surfaces and edges. Seams and shadows provide meaning about what you can touch." The material design language will not only be used on Android, but across Google's suite of web software as well, providing a consistent experience across all platforms.〔(【引用サイトリンク】url=http://www.engadget.com/2014/06/25/googles-new-design-language-is-called-material-design/ )〕〔(【引用サイトリンク】url=http://www.anandtech.com/show/8207/google-reveals-details-about-android-l-at-google-io )〕〔(【引用サイトリンク】url=http://www.fastcodesign.com/3032378/googles-new-improved-android-will-deliver-a-unified-design-language )〕〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Android Lollipop」の詳細全文を読む スポンサード リンク
