Android同步顯示系統之研究

本論文主要在Android系統上，開發一個可以在手機上同步顯示文件、圖片及播放音樂的應用程式。當一群人聚在一起活動的時候，有時候需要分享一些訊息、照片或音樂，但是卻沒有投影及廣播的設備，這時候就可以使用本論文所開發的應用程式，把每個人的手機連接起來，由分享者上傳及廣播他所要分享的內容，其他人的手機就會同步顯示文件內容或播放音樂，就像是一個行動式的廣播系統一樣。本研究所開發的系統，主要使用WebSocket技術，來做為各行動裝置之間同步的機制。使用者的手機會連上預先建置的伺服器，並將分享者傳送的訊息推送到每個接收者的行動裝置上，以達到同步顯示及播放的效果。

In this thesis, we develop an Android application which can simultaneously display the same text, image, or play music in different smartphones. When a group of people gather together, sometimes they want to share some messages, photos or music, but there is no projection and broadcast equipment. At this time, you can use the proposed application to connect everyone's mobile phones. The sharer uploads and broadcasts the content he wants to share, and other people's mobile phones will simultaneously display the file content or play the music, just like a mobile broadcast system. The proposed system uses WebSocket technology as the synchronizing mechanism between mobile devices. The user's mobile phone will be connected to the pre-built server, and the message transmitted by the sharer will be pushed to the mobile device of each recipient to achieve synchronous display and playback.
