Android系統自2008年10月上市以來，投入的廠商越來越多，根據ComScore的調查報告，今年一月美國的智慧型手機有31.2%是Android系統，正式超過了RIM的黑莓機，也就是Android系統的手機從開始上市到市占率第一只花了27個月就達到目標，成為最受消費者歡迎及成長率最快的手機作業系統。

但Android本著開放源碼讓所有人都能取得系統原始碼，使得Android已經不只被用在行動電話系統上，例如智慧型電視，機上盒，平板電腦，PC，車用電子(導航或影音系統)，甚至工業控制電腦上，而硬體平台也不只被移植到ARM系統上，其他如X86或MIPS等都能成功的移植，基本上有支援LINUX 2.6.29及之後版本作業系統的硬體平台多半能順利的移植，而越來越多樣的產品線採用Android後，使得越來越多廠商熟悉這平台，進而開發出更多的應用程式，因此又吸引更多的消費者購買Android相關的產品，市場做大後又能創造出更多的廠商投入，使得未來熟悉Android開發的技術人才會是電子產品市場亟需要的人力資源。

本論文是以TI的OMAP 3530(ARM Cortex A8 Core)硬體平台來實作整個系統的移植，其中包含底層硬體驅動程式的移植，到中間的中介層(Middle Ware)，最後到上層的應用程式開發環境建立到完成一個DLNA Player應用程式的過程，希望能作為想進入Android平台開發的人員作為參考的資源之一。

More and more vendors have used Android system since it launched October 2008. According to the survey from ComScore, Android system holds an overall US’s smart phone market shares of 31.2%, surpassing RIM’s blackberry. In other words, the mobile handsets with Android system only spend 27 months to reach the target of the first market share since it launched in the beginning and become the most popular to consumers and fastest growth rate of mobile operating system.

Everyone can access the system source code from Android with open source code and consequently Android not only be used on the mobile phone system but others such as smart TVs, set-top boxes, tablet PCs, PCs, automotive electronics (navigation or entertainment system) and even the industrial computers. In terms of hardware platform, it can be ported not only on the ARM system but also X86 or MIPS successfully. Basically most of the hardware platform support LINUX 2.6.29 and its update version can be ported with Android system smoothly. More and more vendors are familiar with this platform due to more and more products adopted with Android; therefore more Apps are under development and attract more consumers to buy Android-related products. Bigger market share will cause investment from more vendors and this will make technical of talents who are familiar with Android system development are in great demand in terms of human resource of electronics market.

The thesis is using TI’s OMAP 3530(ARM Cortex A8 Core)as the hardware platform to implement the system porting which contains the accomplishment for whole progress of DLNA Player application program from porting driver at the bottom layer through the middle wave at the middle layer then to the application development of programming environment at the most upper layer. Recommend it to be one of the resources to the entry-level of Android system developers.
