The Evolution of Android

Google, seeing a large growth of Internet use and search in mobile devices, acquired Android, Inc., in 2005 to focus its development on a mobile device platform. Apple introduced the iPhone in 2007 with some ground-breaking ideas including multitouch and an open market for applications. Android was quickly adapted to include these features and to offer definite distinctions, such as more control for developers and multitasking. In addition, Android incorporates enterprise requirements, such as exchange support, remote wipe, and Virtual Private Network (VPN) support, to go after the enterprise market that Research In Motion has developed and held so well with its Blackberry models.

Device diversity and quick adaptation have helped Android grow its user base, but it comes with potential challenges for developers. Applications need to support multiple screen sizes, resolution ratios, keyboards, hardware sensors, OS versions, wireless data rates, and system configurations. Each can lead to different and unpredictable behavior, but testing applications across all environments is an impossible task.

Android has therefore been constructed to ensure as uniform an experience across platforms as possible. By abstracting the hardware differences, Android OS tries to insulate applications from device-specific modifications while providing the flexibility to tune aspects as needed. Future-proofing of applications to the introduction of new hardware platforms and OS updates is also a consideration. This mostly works as long as the developer is well aware of this systematic approach.The generic Application Programming Interfaces (API) that Android offers and how to ensure device and OS compatibility are main threads discussed throughout this book.

Still, as with any embedded platform, extensive testing of applications is required. Google provides assistance to third-party developers in many forms as Android Development Tool (ADT) plugins for Eclipse (also as standalone tools) including real-time logging capabilities, a realistic emulator that runs native ARM code, and in-field error reports from users to developers of Android Market applications.

Character Building Thought Power

Character-Building Thought Power by Ralph Waldo Trine. Ralph draws a distinct line between bad and good habits. In this book, every effort is made by the writer to explain what comprises good habits and why every one needs it early in life. It draws the conclusion that habits nurtured in early life concretize into impulses in future for the good or bad of the subject.
