28. WHAT IS ANDROID ARCHITECTURE?

29.  Application
• Android will ship with a set of core applications including an email
client, SMS program, calendar, maps, browser, contacts, and others. All
applications are written using the Java programming language.
 Application Framework
• The application framework provides the classes used to create Android
applications. It also provides a generic abstraction for hardware access
and manages the user interface and application resources.
 Libraries
• While Android development is done in Java, Dalvik is not a Java VM.T
he core Android libraries provide most of the functionality available in
the core Java libraries as well as the Android-specific libraries.

30.  Android Runtime
• Android includes a set of core libraries that provides most of the
functionality available in the core libraries of the Java programming
language.
• Every Android application runs in its own process, with its own
instance of the Dalvik virtual machine.
• Dalvik has been written so that a device can run multiple VMs
efficiently.
 Linux Kernel
• Android relies on Linux version 2.6 for core system services such as
security, memory management, process management, network stack,
and driver model. The kernel also acts as an abstraction layer between
the hardware and the rest of the software stack.
