Android security architecture or the Android software stack on top of the Linux kernel is the hardware
abstraction layer H a l.
This layer provides a standard method for creating software hooks between the Android platform staff
and the hardware.
The how allows to implement functionality without affecting or modifying the higher level systems.
As you can see, we have five layers.
Let's go more into the details of these layers and explain further.
And the next layer to the hell.
The library's component acts as a translation between the Kernell and the application framework.
The native libraries in Android are written in C and C++, most of which are ported from Linux but are
exposed to developers through a Java API.
At the same level, there are also components from the Android runtime and core libraries.
The virtual machine is an important part of the Android operating system and execute system.
And third party applications.
At the next level, the Android framework layer provides a suite of services or systems that are useful
when writing applications.
Commonly referred to the application programming interface, or Java API framework, which is one of
the building blocks for the final system or end user applications.
The top most layer is the application layer, which is the layer close to the end user.
All finished developed products will execute in the space by using the API libraries and the runtime
environments.
