Android N final - 2

Rilasciato Android N developer preview 4: ecco le novità ed i link per il download (foto)

Andrea Centorrino -

A distanza di quasi un mese dalla Developer Preview 3, la prima versione beta di Android N, Google rilascia la quarta iterazione, insieme ad una nuova versione dello SDK con la versione finale delle API 24.

Non facciamo perdere tempo ai più impazienti, ed iniziamo subito con i link per il download delle factory image della build NPD56N, presi direttamente dalla pagina per gli sviluppatori:

Chi non volesse formattare, ma non potesse attendere l’aggiornamento OTA, potrà scaricarlo dai seguenti link (qui la pagina ufficiale):

Oltre alla già citata finalizzazione delle API 24, troviamo la conseguente possibilità per gli sviluppatori di pubblicare app per Android N nei canali alpha, beta e production del Play Store. Inoltre, Android N developer preview 4 cela un nuovo easter egg, relativo al nome finale (non ancora svelato).

LEGGI ANCHE: Il nome di Android N sarà svelato tra qualche settimana

Durante l’ultimo I/O, il vice-presidente Android Dave Burke aveva scherzato suggerendo il nome “Namey McNameface“, che ora potrete trovare davvero in N (guardare l’immagine in basso per credere!); inoltre è cambiata anche l’animazione durante un aggiornamento di sistema: addio androidino, benvenuto cerchio colorato (sempre in galleria ci sono le prove). Qui sotto riportiamo un changelog parziale, che comunque non rivela niente di davvero nuovo per gli utenti. Voi avete notato qualche novità?

Aggiornamento 17/06: La developer preview 4 è in rollout anche per Xperia Z3 via OTA.

Cosa è stato aggiunto

  • In previous versions of Android, an app activates with all of its locale resources loaded before locale negotiation begins. Starting in Android N DP4, the system negotiates resource locales individually for each resource object before the app activates.
  • As announced at Developer Preview 3, we’ve deferred the Launcher Shortcuts feature to a later release of Android. In Developer Preview 4, we’ve removed the Launcher Shortcuts APIs.
  • We’ve changed the BLE Scanning behavior starting in DP4. We’ll prevent applications from starting and stopping scans more than 5 times in 30 seconds. For long running scans, we’ll convert them into opportunistic scans.
  • The Multi-Window android:minimalHeight and android:minimalWidth attributes have been renamed to android:minHeight and android:minWidth.
  • La modalità notturna rimane attivabile solo dai quick setting.

Cosa non funziona:

Stability

-Users may encounter system instability (such as kernel panics and crashes).

Launcher

-The default launcher’s All Apps tray may become unresponsive after cycling the screen off and on. Returning to the homescreen and relaunching the All Apps tray may resolve this issue.

Setup Wizard

-Crash on selecting “Not now” in “Set up email” screen.

Media

-Media playback may be unreliable on Nexus 9 and Nexus Player, including issues playing HD video.
-Occasional freeze when running the YouTube app with other apps in multi-window mode on Pixel C devices. In some cases hard reboot is required.
-Apps may have issues playing some Widevine DRM-protected content on Nexus 9 devices.
-Issues handling VP8 video on Nexus 9 devices.

External storage

-Apps may become unstable when the user moves them from internal storage to adoptable external storage (this can include SD card or devices attached over USB).

Screen zoom and multiple APKs in Google Play

-On devices running Android N, Google Play services 9.0.83 incorrectly reports the current screen density rather than the stable screen density. When screen zoom is enabled on these devices, this can cause Google Play to select a version of a multi-APK app that’s designed for smaller screens. This issue is fixed in the next version of Google Play services and will be included in a later Developer Preview release.

Vulkan support and multiple APKs in Google Play

-On devices running Android N, Google Play services 9.0.83 currently reports Vulkan support but not Vulkan version. This can cause Google Play to select a version of a multi-APK app that’s designed for lower Vulkan support on devices with higher version support. Currently, the Google Play Store does not accept uploads of apps which use Vulkan version targeting. This support will be added to the Google Play Store in the future and fixed in the next version of Google Play services (to be included in a later Developer Preview release). Any N devices using the version of Google Play services 9.0.83 will continue to receive versions of apps targeting basic Vulkan support.

Accessibility

-Switch access doesn’t allow user to navigate web pages in Chrome.
-Accessibility issues for talkback users with notification dismissal, and wifi selection screen.

Android for Work

-Currently, CA certificates provisioned through DevicePolicyManager are not available to profiles other than the primary user/profile due to a preload issue. For example, this could prevent a user from connecting to a trusted server when in a Work profile. This issue will be resolved in the next Developer Preview.
