Treble : Manufacturers to update devices to a new version of Android very easily

I am happy that google has introduces new framework where manufacturer can update OS very easily & test with new OS.

> The Android 8.0 release includes Project Treble.

> Android OS framework designed to make it easier, faster, and less costly for manufacturers to update devices to a new version of Android.

> Treble separates the vendor implementation (device-specific, lower-level software written by silicon manufacturers) from the Android OS framework via a new vendor interface.

> Android 7.x and earlier, no formal vendor interface exists so device makers must update large portions of the Android code to move a device to a newer version of Android

> With Treble, a new stable vendor interface provides access to the hardware-specific parts of Android, enabling device makers to deliver new Android releases simply by updating the Android OS framework—without any additional work required from the silicon manufacturers


For details on the new Treble architecture, see the following sections:

  • HAL Types. Describes binderized, passthrough, Same-Process (SP), and legacy HALs.
  • HIDL (General). Contains general information about the HAL interface definition language (HIDL, pronounced "hide-l"), which is an interface description language (IDL) to specify the interface between a HAL and its users.
  • HIDL (C++). Contains details for creating C++ implementations of HIDL interfaces.
  • HIDL (Java). Contains details about the Java frontend for HIDL interfaces.
  • ConfigStore HAL. Describes the ConfigStore HAL, which provides a set of APIs for accessing read-only configuration items used to configure the Android framework.
  • Device Tree Overlays. Provides details on using device tree overlays (DTOs) in Android.
  • Vendor Native Development Kit (VNDK). Describes the VNDK, which is a set of libraries exclusively for vendors to implement their HALs.
  • Vendor Interface Object (VINTF). VINTF objects aggregate relevant information about a device and make that information available through a queryable API.
  • SELinux for Android 8.0. Details SELinux changes and customizations.

Hopefully manufacturers provide the updates as early as possible.

Google re-branded the support Android libraries to AndroidX

It is important to note, you cannot mix AppCompat and Jetpack in the same project. You must convert everything to use Jetpack if you want to upgrade. The support library artifacts are being deprecated and all future development is going into AndroidX , so there's no avoiding this migration. Alan Viverette sums this up nicely: “There won’t be a 29.0.0, so Android Q APIs will only be in AndroidX” The stable release of 28.0.0 will be the final feature release packaged as android.support . All subsequent feature releases will only be made available as androidx-packaged artifacts. Below tips will give you a clearer transition path. The current version of AppCompat (v28.x) is exactly the same as AndroidX (v1.x). In fact, the AppCompat libraries are machine generated by changing maven coordinates and package names of the AndroidX codebase. For example, android.support.v7.app.AppCompatActivity is now androidx.appcompat.app.AppCompatActivity For a complete listi...

Android Beginners Guide

                                                                                                               Android Operation System: Android is an operating system based on Linux with a Java programming interface. It provides tools, e.g. a compiler, debugger and a device emulator as well as its own Java Virtual machine (Dalvik Virtual Machine - DVM). Android is created by the Open Handset Alliance which is lead by Google. Android uses a special virtual machine, e.g. the Dalvik Virtual Machine. Dalvik uses special bytecode. Therefore you cannot run standard Java bytecode on Android. Android provides a tool "dx" which allows to convert Java Class files into "dex" (Dalvik Executable) files. Android ...

Kotlin and Android

Kotlin is now an official language on Android. It's expressive, concise, and powerful. Best of all, it's interoperable with our existing Android languages and runtime. To use Kotlin in Android Studio prior to version 3.0 you have to manually install the Kotlin plugin. To do so, start Android Studio and open Plugins from the Configure menu . In the opened dialog, search for Kotlin , select the corresponding plugin and press Install . Kotlin for Android Development: Kotlin is a great fit for developing Android applications, bringing all of the advantages of a modern language to the Android platform without introducing any new restrictions. Compatibility: Kotlin is fully compatible with JDK 6, ensuring that Kotlin applications can run on older Android devices with no issues. The Kotlin tooling is fully supported in Android Studio and compatible with the Android build system. Performance: A Kotlin application runs as fast as an equivalent Java one, thanks to ver...
