Google has enrolled the Android 8.1 but only or the beta testing to showcase the upcoming Android features. The only thing that I hate about the Pixel line of Google is that these smartphones always teases with the latest Stock Android updates that I can't have. According to the search giant, the upcoming Android update will give users more efficient and interactive features. However, the public release of the Android 8.1 is expected to hit the market somewhere in December. Right now, the Android 8.1 developer preview is available only for the beta testers and supported devices are Nexus 5X, Nexus 6P, Pixel C, Pixel, Pixel XL, Pixel 2, and Pixel 2 XL.

With the all-new Android 8.1, the power menu is also changed by the company with a neat and simplified design.

The "Power Off" and the "Restart" button now will be available next to your fingers and you don't need to fumble your fingers to shutdown or restart the device.

4. Search Setting Option

Along with a few designing tweaks, Google has also revamped the settings app of the platform. With PIxel 2, the company added a search option in the settings app to ease in finding the settings option to the users. With the search option, the settings app looks more managed and easy to access any minor or major setting. Along with this, some of the settings options are also rearranged in the app's options list.

5. Oreo Easter Egg is Different

There is no updated version of Android from the company without a new easter egg for the users. With 8.1 you will be getting a new easter egg including the Oreo in it which company added after users got disappointed with the Android 8.0 launch after not finding the Oreo in it. By tapping the Android version in settings seven times you will see an Oreo with bugdroid embedded in it.

6. Only One Notification Per Second For the Apps

According to the documentation of the Android 8.1 developer preview made available by Google, the applications are allowed to make only one notification per second. To understand this consider the situation when you reconnect your phone to the internet and all the pending notification starts popping into the phone. Isn't it really annoying? With the Android 8.1, the apps are allowed to give only one notification tone per second irrespective of the number of notifications from the app.

7. Quick Settings Panel Gone Transparent

The quick setting panel also receives some of the minor tweaks which makes it more interactive. Google gave the quick setting panel a translucent look which reflects the Pixel 2 system design and the functionality and works system-wide. Along with this, the user icon also has been removed from the panel which means you need to navigate to the settings app to switch between the users.

However, there some also some tweaks including the option to remove "apps using battery" option and "WiFi on during sleep" but these are the most eminent features and changes in the Android 8.1. Google may apply furthermore changes to the version prior to the public launch of Android 8.1.

Shared memory API

Android 8.1 (API level 27) introduces a new SharedMemory API. This class allows you to create, map, and manage an anonymous SharedMemory instance. You set the memory protection on a SharedMemory object for reading and/or writing, and, since the SharedMemory object is Parcelable, you can easily pass it to another process through AIDL.

The SharedMemory API interoperates with the ASharedMemory facility in the NDK. ASharedMemory gives access to a file descriptor, which can then be mapped to read and write. It's a great way to share large amounts of data between apps or between multiple processes within a single app.

WallpaperColors API

Android 8.1 (API level 27) allows your live wallpaper to provide color information to the system UI. You do this by creating a WallpaperColors object from a bitmap, a drawable, or by using three manually-selected colors. You can also retrieve this color information.

To create a WallpaperColors object, do either of the following:

  • To create a WallpaperColors object by using three colors, create an instance of the WallpaperColorsclass by passing the primary, the secondary, and the tertiary color. The primary color must not be null.
  • To create a WallpaperColors object from a bitmap, call the fromBitmap() method by passing the bitmap source as parameter.
  • To create a WallpaperColors object from a drawable, call the fromDrawable() method by passing the drawable source as parameter.

To retrieve the primary, secondary, or tertiary color details from the wallpaper, call the following methods:

To notify the system about any significant color changes in your live wallpaper, call the notifyColorsChanged() method. This method triggers an onComputeColors() lifecycle event where you have an opportunity to provide a new WallpaperColors object.

To add a listener for color changes, you can call the addOnColorsChangedListener() method. You can also call the getWallpaperColors() method to retrieve the primary colors of a wallpaper.
