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

TI Android market view
Very traditional
Semi - traditional
Unconventional
The Android architecture is
flexible enough that it is getting
used in unconventional products
like Rugged PDA, Medical UI,
Industrial devices etc
Android architecture is
intended to solve the
software issues for
mobile devices
Android architecture is readily
applied into Semi-traditional
devices like MID, Video Conf
apps, etc

Introducing TI Android DevKit
Explain Android Stack and TI’s responsibility What TI adds in Android Development and release model
- Android provides Std. phone apps- Android Market provides more apps
Our “TI” main FOCUS- Implement HAL- Port Linux Device Drivers- Integrate SGX drivers, Flash libraries, etc- Provide Boot loader, docs, tests
- TI will enable & support framework’s based on customer needs
System wide tasks for TI include
- Validation / System testing
- Benchmarking
- Get Android CTS
- Design solution to customer problems (NDK, apps, etc)
- Collaterals
- OOB
- Package and release TI DevKit

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.
