NOW WHAT IS THE DATABASE STRUCTURE OF ANDROID

The basic layer is the Linux kernel. The whole Android OS is built on top of the Linux 2.6 Kernel with some further architectural changes made by Google.  It is this Linux that interacts with the hardware and contains all the essential hardware drivers. Drivers are programs that control and communicate with the hardware.

LINUX KERNEL

Applications are the top layer in the Android architecture and this is where our applications are goanna fit. Several standard applications comes pre-installed with every device, such as:

SMS client app Phone Web browser Contact manager etc…….

APPLICATION

These are the blocks that our applications directly interacts with. These programs manage the basic functions of phone like resource management, voice call management etc. As a developer, you just consider these are some basic tools with which we are building our applications.

Important blocks of Application framework are: Activity Manager

Content Providers Telephony Manager

etc…….

APPLICATION FRAMEWORK

The next layer is the Android’s native libraries. It is this layer that enables the device to handle different types of data. These libraries are written in c or c++ language and are specific for a particular hardware.

Some of the important native libraries include the following:

Surface Manager Media framework SQLite etc…..

LIBRARIES

Android Runtime consists of Dalvik Virtual machine and Core Java libraries.
