Android is an open source software platform that can be adapted to work on various hardware configurations. It uses Linux for device drivers and process management, and includes native libraries and the Dalvik virtual machine. Android supports wireless connectivity standards like GSM, 3G, Edge, and WiFi. Each application runs in its own process with security enforced through permissions. While early versions had some Bluetooth and app limitations, more recent Android versions now support Firefox Mobile.

- 8. The All Apps launcher (left) and resizable widgets (right) give you apps and rich content from the home screen.
- 10. The Recent Apps list makes multitasking simple. Jump to the camera or see notifications without unlocking. For incoming calls, you can respond instantly by text.
- 11. Data usage controls let you monitor total usage by network type and application and then set limits if needed.
- 16. 2. Platform (2) 2.2 Operating System(s) • Android uses Linux for its device drivers, memory management, process management, and networking. • The next level up contains the Android native libraries. They are all written in C/C++ internally, but you’ll be calling them through Java interfaces. In this layer you can find the Surface Manager, 2D and 3D graphics, Media codecs, the SQL database (SQLite), and a native web browser engine (WebKit). • Dalvik Virtual Machine. Dalvik runs dex files, which are coverted at compile time from standard class and jar files.

- 18. 2. Platform (4) 2.4 Security Android is a multi-process system, in which each application (and parts of the system) runs in its own process. Most security between applications and the system is enforced at the process level through standard Linux facilities, such as user and group IDs that are assigned to applications. Additional finer-grained security features are provided through a "permission" mechanism that enforces restrictions on the specific operations that a particular process can perform, and per-URI permissions for granting ad-hoc access to specific pieces of data.

Platform (6) 2.6 Future possibilities • Google Android Sales to Overtake iPhone in 2012 • The OHA is committed to make their vision a reality: to deploy the Android platform for every mobile operator, handset manufacturers and developers to build innovative devices • Intel doesn’t want to lose ownership of the netbook market, so they need to prepare for anything, including Android • Fujitsu launched an initiative to offer consulting and engineering expertise to help run Android on embedded hardware, which aside from cellphones, mobile internet devices, and portable media players, could include GPS devices, thin- client computers and set-top boxes. • More Android devices are coming and some will push the envelope even further
