Android is a software product for mobile devices that has three major parts:
- operating system
- middleware
- key applications
Android Architecture
Here are the major components based on this [source]
Key principles
1. Linux Kernel - proven driver model, memory and process management, etc. (a core service of a reliable operating system)
2. Libraries (written in C/C++)
| Component | Responsability |
|---|---|
| Surface Manager | composing drawing surface onto the screen |
| ES & SGL | core of graphics libraries |
| Media Framework | core media: mpeg,mp3,ect. |
| Media Framework | core media: mpeg,mp3,ect.
