What is android kitkat and lollipop

Разница между Android KitKat и Lollipop

В середине октября 2014 года компания Google показала миру три новых устройства линейки Nexus и новую версию операционной системы Android – 5.0 Lollipop. Вокруг этой версии ходило много слухов по поводу ее названия. Предполагалось, что пятая версия Android получит название «Lemon Meringue Pie», или просто «L», но в итоге Google остановилась на названии Lollipop, которое в переводе с английского языка означает «леденец». Новая версия операционки в корне отличается от предыдущих версий как внешним видом, так и производительностью. Разберемся в том, чем отличается Android KitKat от Lollipop.

После официального релиза Android Lollipop разработчики из Google рассказали, что первые версии «леденцового» андроида получат новые Nexus 6 и 9, а также Nexus 5, 7 (2012 и 2013 года), Nexus 10 и устройства от сторонних производителей в версиях Google Play Edition. Что касается других планшетов и смартфонов, то их производители будут сами решать, обновлять платформу или нет. Топовые флагманы, несомненно, получат обновление до 5.0, а вот средний сегмент и бюджетный класс могут остаться без Android Lollipop.

Material Design

Первое, что бросается в глаза, это измененный дизайн интерфейса. Новый «Material Design» делает интерфейс более «плоским». Подобный переход на «плоский» дизайн компания Apple предприняла в iOS 7. Обновленное оформление появится как в настройках системы, так и в приложениях от компании Google. Спустя пару дней после официального релиза устройств компания Google выпустила специальный SDK, в котором присутствует набор инструментов для создания приложений под новый «материальный дизайн».

Улучшение производительности и автономности

Компания Google в новой версии Android решила избавиться от среды Dalvik. Главное отличие Android KitKat от Lollipop состоит именно в среде выполнения: в KitKat у пользователя был выбор между Dalvik и ART. В новом Lollipop такого выбора уже нет, поскольку среда выполнения ART установлена по умолчанию. Благодаря поддержке новой версией андроида 64-разрядных процессоров и переходу на ART производительность операционной системы увеличилась в 4 раза.

За счет оптимизации пятой версии Android удалось увеличить время автономной работы устройств в среднем на полтора часа. Кроме того, при зарядке устройства пользователь получит информацию о расчетном времени, необходимом для полного заряда аккумулятора.

Работа с безопасностью

В новой пятой версии Android Google улучшила безопасность различными дополнительными функциями. Так, появился аналог функции «Kill Switch», который позволяет блокировать устройство на расстоянии и защитить устройство от перепрошивки и взлома. Функция «Factory Reset Protection» дает возможность пользователю установить специальный пароль, без которого нельзя сделать хард-ресет (полный сброс) устройства. При этом без данного пароля нельзя будет прошить устройство. Благодаря сервису «Android Device Manager» владелец потерянного или украденного смартфона сможет удаленно заблокировать и очистить устройство.

Появление функции «Android Smart Lock» увеличит количество «носимых» устройств. К примеру, при помощи «умных» часов или специального гаджета (кольцо с NFC-меткой) можно будет разблокировать планшет или смартфон на Android.

Новые функции и улучшенный многопользовательский режим

В «пятерке» появился аналог функции «Ambient display», который выводит на экран блокировки уведомления о звонках, SMS и других важных событиях. Как только пользователь возьмет в руки телефон или планшет, на экране отобразится окно блокировки с уведомлениями. Данная функция уже доступна владельцам Moto X, но вполне вероятно, и топовые устройства получат возможность вывода уведомлений на экране блокировки.

Google улучшила многопользовательский режим, добавив в него режимы «Гость» и «Закрепленный экран». Кроме этого, ваш смартфон, привязанный к Google-аккаунту, будет доступен из интернета. Авторизуйтесь в Google и получите доступ к контактам, фотографиям и сообщениям на смартфоне\планшете, работающем на Android Lollipop.

Несомненно, часть изменений Google скрыла от пользователей. Обо всех новых штучках и функциях владельцы Android-устройств узнают лишь после официального релиза Lollipop, который намечен на 3 ноября 2014 года. Видеообзор новой версии представлен на следующем видео:

7 reasons why KitKat is still better than Lollipop

Wanting an upgrade to the latest version of Android is understandable — after all, in theory it should be the one with the best features and the fastest performance. In practice though, that’s not always the case, and there are several reasons why you might want to hold off on a Lollipop upgrade. Read on for our KitKat vs Lollipop comparison — and why Android 4.4 KitKat is still better.

That’s if you have the option of course: Your handset might not be getting Lollipop, or it might have been waiting for a very long time. Whatever the situation, here are seven areas where we think Android 4.4 KitKat beats out Android 5.x Lollipop — let us know if you agree in the comments.

1. Battery life

Lollipop brings its Project Volta optimizations and promises of a better battery life for your device, but that doesn’t necessarily work out in the real world: In the tests run by GSM Arena, the Nexus 5 and the LG G3 actually suffered from worse battery life after the upgrade. At the very least check the benchmarks for your handset before pushing the upgrade button.

2. Streamlined lock screen

As you may know if you’ve searched through the feature lists, Android Lollipop brings notifications to the lock screen — that means anyone picking up your phone can see your alerts (though sensitive content can be hidden). If you want a more streamlined, less cluttered lock screen, then you’re better off sticking with KitKat for the time being.

3. Better multitasking

Google has made some tweaks to the way multitasking works in Lollipop which may or may not be to your tastes. Each browser window and open document counts as an extra pane on the multitasking screen, so it gets more crowded more quickly, and the open apps stay open even after a reboot so you can’t quickly clear everything out from the memory.

4. No silent mode

One of the most baffling decisions made by Google in Lollipop was the removal of the silent mode shortcut — accessed by a long press on the Power button — that let you quickly mute your phone. You can of course mute a Lollipop handset but it’s a much more complicated process and the old Power shortcut has been cut for no apparent reason.

5. Interface tweaks

Beauty is in the eye of the beholder as far as OS design goes but not everyone is happy with Lollipop’s revamped navigation buttons and the white apps drawer that you can’t edit without installing an alternative launcher. The Material Design has been widely heralded as an improvement by most, but for some it looks a little garish and cartoonish.

6. Lock screen widgets

If you’re a fan of lock screen widgets then you won’t like the Lollipop upgrade — they’re no longer supported. Why Google decided to give them the chop isn’t clear, but maybe the new lock screen notifications have something to do with it. If there are certain lock screen widgets that you rely on, then you’re better off sticking with Android KitKat for the time being.

7. App compatibility

Of course Google has been quick to update its official apps for Android, and many of the big names have done the same, but smaller and older apps can throw up bugs and complications when running with the new-look Lollipop. If a handful of your favorite apps haven’t been updated to be fully compatible with Android 5.x, you might want to hold fire on upgrading.
