<li>New <strong><a href=
"http://tools.android.com/tech-docs/layout-inspector">Layout
Inspector</a></strong> lets you examine snapshots of your layout hierarchy
while your app is running on the emulator or a device.
</li>

<li>New <strong><a href="/studio/write/firebase.html">Assistant</a></strong>
window to help you integrate Firebase services into your app.
</li>

<li>New <strong><a href="/studio/debug/apk-analyzer.html">APK

"http://tools.android.com/tech-docs/build-cache">build cache</a></strong>
(currently experimental) to speed up build performance.
</li>

<li>New <strong>C/C++ build integration with CMake and ndk-build</strong>.
Compile and build new or existing native code into libraries packaged into
your APK, and debug using lldb. For new projects, Android Studio uses CMake
by default, but also supports ndk-build for existing projects. To learn how
to include native code in your Android application, read <a href=
"/studio/projects/add-native-code.html">Add C and C++ Code to Your
Project</a>. To learn how to debug native code with lldb, see <a href=
"/studio/debug/index.html#debug-native">Debug Native Code</a>.
</li>

<li>New <strong><a href="/studio/intro/index.html#sample-code">Samples
Browser</a></strong> so you can easily look up Google Android sample code
from within Android Studio to jump start app development.
</li>

<li>New <strong>Merged Manifest Viewer</strong> to help you diagnose how your
manifest file merges with your app dependencies across project build
variants.
</li>

<li>The <strong>Run</strong> window now contains log messages for the current

Location</strong> and checking the <strong>Use embedded JDK</strong>
checkbox.

Zmiany

Zaktualizowano kod źródłowy IDE z IntelliJ 15 na IntelliJ 2016.1
Instant Run wymaga teraz zainstalowania pakietu SDK platformy odpowiadającego docelowym poziomom API urządzeń.
Funkcja Szybkie uruchamianie zostanie automatycznie wyłączona, jeśli użytkownik uruchamia aplikację w profilu służbowym lub jako użytkownik dodatkowy.
Rozwiązaliśmy wiele problemów z niezawodnością Instant Run, w których zmiany nie były wdrażane lub aplikacja się zawieszała:
- Niektóre zasoby aplikacji nie zostały wdrożone do uruchomionej aplikacji (błąd: #213454).
- Aplikacja ulega awarii, gdy użytkownik przechodzi między sesjami Instant Run a sesjami, w których nie jest używana technologia Instant Run, a klasa Serializable nie ma zdefiniowanej wartości serialVersionUID. (Błąd: #209006)
- Zmiany stylu nie są uwzględniane w ramach Instant Run. (Błąd: #210851)
- Sesja Instant Run jest niestabilna i powoduje błąd FileNotFoundException. (Błąd: #213083)
- Zmiany w plikach drawable nie są odzwierciedlane, dopóki nie zostanie przeprowadzone pełne przebudowanie w przypadku KitKat. (Błąd: #21530)
- Zmiany zasobów nie są odzwierciedlane w Instant Run, gdy niestandardowe zestawy źródeł zawierają zagnieżdżone ścieżki. (Błąd: #219145)
- Wymiana na gorąco i na zimno nie działa, jeśli zmieniona klasa zawiera adnotację z wartością z enumeracji. (Błąd: #209047)
- Zmiany w danych adnotacji nie są uwzględniane w ramach funkcji Instant Run. (Błąd: #210089)
- Jeśli wprowadzasz zmiany poza IDE, Instant Run ich nie uwzględnia. (Błąd: #213205)
- Sesja Instant Run jest niewiarygodna z powodu niezgodności tokena bezpieczeństwa. (Błąd: #211989
- Wymiana na zimno nie działa na urządzeniach, które nie obsługują prawidłowo funkcji run-as. (Błąd: #210875)
- Aplikacja ulega awarii po ponownym uruchomieniu Instant Run. (Błąd: #219744)
- Wyjątek ClassNotFoundException podczas przechodzenia z Instant Run do Instant Debug. (Błąd: #215805)
