Android system architecture

1. linux kernel layer (linux kernel)

This is the lowest layer of the system architecture. This layer provides drivers for the hardware of android devices.

2. LIBRARIES)

This layer is the penultimate layer. Some c/c ++ libraries are used to provide some major features for the android system. For example, the SQLite Library provides database support.

At the same time, there is a library for running android, which mainly provides some core libraries that allow developers to write android applications in java.

3. APPLICATION FRAMEWORK)

This layer provides the APIs used to build applications.

4. Application Layer (APPLICATIONS)

All applications installed on mobile phones belong to this layer. For example, contacts and text messages on mobile phones.

 

This architecture can also be used to write android programs, but it is more conducive to programming android programs.
