Dodaliśmy więcej opcji dostosowywania w Androidzie 12, aby zwiększyć komfort użytkowania i kompatybilność na urządzeniach telewizyjnych. Najważniejsze zmiany w przypadku telewizorów to ulepszenia odtwarzania multimediów, bardziej zaawansowane funkcje interfejsu użytkownika oraz ulepszenia w zakresie prywatności i bezpieczeństwa. Dodatkowo wprowadzamy lepsze standardy, aby obsługiwać i ulepszać HDMI oraz tunery.
Oto przegląd nowości w Androidzie 12 na telewizory:
Pełną listę zmian wprowadzonych w Androidzie 12 znajdziesz w dokumentacji Androida 12. Pamiętaj, że nie wszystkie funkcje
są dostępne na telewizorach.
Aby rozpocząć, pobierz obrazy systemu dla zestawu deweloperskiego ADT-3.
Możesz też użyć emulatora Androida na telewizor, który umożliwia wypróbowanie niektórych nowych funkcji interfejsu, takich jak rozmycie tła i obsługa interfejsu w jakości 4K.
Od czego zacząć
Jeśli masz urządzenie deweloperskie ADT-3, automatycznie otrzymasz aktualizację OTA do Androida 12. Możesz też zainstalować Androida 12, wykonując te czynności:
Użyj zestawu deweloperskiego ADT-3 na Androida TV. Dostarczony obraz systemu jest przeznaczony tylko na urządzenia deweloperskie ADT-3.
Pobierz obraz systemu.
Zainstaluj obraz systemu na urządzeniu ADT-3.
Ręczne instalowanie obrazów systemu
Możesz pobrać najnowszy obraz systemu Android 12 i ręcznie wgrać go na urządzenie testowe. Ręczne flashowanie urządzenia zapewnia precyzyjną kontrolę nad środowiskiem testowym i może być przeprowadzane za pomocą narzędzi wiersza poleceń.
Po utworzeniu kopii zapasowej danych urządzenia pobierz jedną z tych wersji ADT-3, a następnie wgraj obraz na urządzenie.
