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

intended to solve the
software issues for
mobile devices
The Android architecture is
flexible enough that it is getting
used in unconventional products
like Rugged PDA, Medical UI,
Industrial devices etc

System testing
- Benchmarking
- Get Android CTS
- Design solution
to customer
problems (NDK,
apps, etc)
- Collaterals
- OOB
- Package and
release TI DevKit
- TI will enable &
support framework’s
based on customer
needs
Our “TI” main FOCUS
- Implement HAL
- Port Linux Device
Drivers
- Integrate SGX
drivers, Flash
libraries, etc
- Provide Boot
loader, docs, tests

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.
