電腦發展源於計算用途，由最初龐大硬體設備只有計算中心或大公司才能擁
有發展至今家家戶戶皆能有桌上型電腦。在網際網路掘起後，功能也由工作上的
處理，計算數學轉變到連結每個人的生活，由提筆寫信等待三至五日到現在的
E-mail、MSN 可以立即交談。這些功能帶給人們莫大方便，但有一點前提，電腦
必須在你身邊。
Google 於2007 年11 月5 日公佈最新行動電話系統平台Android。Android
以Linux 核心工作為基礎，這代表著可以將行動電話視為小型電腦，在上面開發
讓使用者可帶著走的應用程式。Facebook 是一個社交網路服務平台。於2004 年
2 月4 日上線，於2010 年其使用者已超過千萬人，透過簡單的文字、圖片連結
人與人之間關係，如此吸引龐大人群，可知人與人之間的交流是個重要議題。
目前行動電話帶給人們非常便利的語言溝通方式，但若想將照片、音樂、文
件、或任何的檔案分享給周遭的朋友就不是那樣的方便。如何能夠立即與朋友分
享自己現在所看到的美景，聽到好聽的音樂，是本論接接下來要討論的，本論文
將探討如何實現手機上的資料同步處理。

In the beginning, computers are developed in need of complex computing. And it
has been evolved from mainframes in enterprise and computer center to desktop at
home. After the rapidly spreading of internet, computer undertakes an important role
in people’s life. It helps us with our work, doing computation, even links people
together through E-mail and instant message software. With computers by our side,
we live a much more convenient life.
Google announced its latest mobile platform operating system “Android” on
November 5th, 2007. Android is constructed base on Linux kernel, which means it
can be treated as a portable computer, with application designed for entertaining,
Internet surfing, and social communication. Social communication has been proven to
be a important issue. For instance, Facebook, a social network service provider online
since February 4th, 2004, creates a place to let people share their messages, photos
and news, has more than ten million user today.
So far the mobile phone has become a very convenient way to communicate, but
if users wish to share photos, music or documents to friends. This thesis is going to
discover a new way to share views, photos, music with friends immediately. This
paper describes the issues with data synchronization between mobile phones.
