Android Overview

What is Android?
• First open, complete, and free platform created
specifically for mobile devices
• Software stack includes
– operating system
– middleware
– key applications.
• New applications can be built easily and access
device‘s capabilities (contacts, wifi etc)

Benefits of Android
• Attractive Licensing
– all core packages are open sourced (Apache 2.0 license)
– usage of the source code for commercial
• Open Source Software
– leverages existing open-source projects
– maintains and manages the sources
– Many hardware-component vendors have decided to provide source code for specific drivers
• Large eco-system
– one of the largest developer community
• not only application layer content (more than 100,000 applications are available)
• but also Android middleware components
• Committed Roadmap
– Android has a relatively frequent major releases and a well maintained roadmap.
• Unlimited Documentation
– The Android community offers a wide variety of instruction content, helps reducing learning
curve

How Android is being Developed?
• At any given moment, there is a current latest release of the Android
platform. This typically takes the form of a branch in the android
trees at Android Open Source Project AOSP.
• Device builders and Contributors work with the current latest
release, fixing bugs, launching new devices, experimenting with new
features, and so on.
• In parallel, Along with many partners (Open Handset Alliance) Google
works internally on the next version of the Android platform and
framework, working according to the product's needs and goals.
• When the "n+1"th version is internally ready, it will be published to
the AOSP, and become the new latest release.
