What is Apple's ecosystem?

They have their own operating system (iOS) based on BSD OS, SDK, Swift language, LLVM, their frameworks, Webkit API, and more. These different classes of software tools and tools are called "software stacking".

What distinguishes Apple is that it has a full range of software class from applications to specialized devices. It has great advantages because it can be improved vertically across different layers. Many specific improvements can be made to their own devices. That's why the Apple app runs smoothly even though its device specifications are not as advanced as the major Android phones.

What is the Android ecosystem?

Now let's take a look at the Android software group mess. In contrast, Google Android follows a completely different way than Apple. Wants to support Android apps on all devices and devices. The layers are "horizontal" but not vertically integrated like Apple.

A variety of target device capabilities Google is running Dalvik VM (or ART) and Timely Complexity (JIT) devices to support its applications. So the Android apps you've downloaded from the Google Play app store are actually "medium" bytes.

When you run your app on Android phones, Android runtime must detect any type of device and set up all the resources it needs. They can then translate online from the argument to the original device icon in Virtual Machine. The virtual machine looks like a "condom" if you know what I'm saying.

Class and class library

These applications are written according to the APIs provided by Google's application frameworks or third-party libraries and databases. These run-time libraries are updated in each Android patch, such as Android Pie or Android Q. Next

The irony is that only a small percentage of devices carry the latest version of Android. Worse still, each API update can be compatible only on a small set of Android devices.

So, even if Google stops working with Huawei for the next Android Q release. Updates are still a small part of Android devices. Most people do not care about the version they use. Huawei can still use the old version of Android if it is really desperate.

Kernel layer

For the bottom layer, Android runtime and virtual machines must interact with the operating system or Linux kernel to access device capabilities such as playback, memory, network, and file system management. This is an open source Linux kernel largely because it holds GPL licenses. So that everyone including Huawei can use this service.
