基于Android的实时共享白板的设计与实现
摘要：随着社会的飞速发展，人们生活水平大大提高，各种需求越来越复杂，因此各种项目的规模越来越大，项目成员越来越复杂，并且他们很有可能分布在不同地点。因此，提高项目组内成员之间沟通协作的效率成为亟待解决的问题。随着互联网的迅猛发展，人们已习惯于通过智能手机上的软件解决问题，他们需要一款简单、便捷、高效的软件来解决上述沟通问题，而众所周知，图文结合的沟通相比纯文字更加直观，也更加高效。基于此，本文研究了实现白板的方法和Android实时通信的技术，发现HTML5的Canvas可以方便地实现白板、HTML5的WebSocket协议可用于实时通信并效率很高、Android的WebView可以实现Java代码和JavaScript代码的互相调用，据此设计并实现了一个基于Android的实时共享白板APP。本软件大致包括以下功能：安排会议、发送会议邀请、加入会议、会内权限管理、会议共享白板、会议群聊、联系人管理、账户管理。总结来说，通过使用本软件，用户不再需要坐在会议室里或电脑前，只要使用Android手机就可以随时随地召开白板会议，与自己的伙伴进行远程沟通与协作，可以有效提高团队成员之间沟通协作的效率。

Design and Implementation of Real-time Sharing Whiteboard Based on Android
Abstract: With the rapid development of society, people’s living standards have been greatly improved and the demand is more and more complex, so the scale of various projects is getting bigger and bigger, the project members are more and more complex and likely to be distributed in different locations. Therefore, improving the efficiency of communication becomes an urgent problem to be solved. With the rapid development of the Internet, people have been accustomed to solve the problem through the software on the smart phone, and now they need a simple, convenient and efficient software to solve the above communication problem, as we all known, graphic communication compared to pure text is more intuitive and more efficient. Based on this, this thesis studied the realization of the drawing board and Android real-time communication technology, found that HTML5 Canvas can easily achieve the drawing board, HTML5 WebSocket protocol can be used for real-time communication and it is efficient, and through Android WebView, Java and JavaScript can call each other easily, and according to this, design and implement a real-time sharing whiteboard APP based on Android. The software mainly includes the following functions: scheduling meetings, sending meeting invitations, joining meetings, permission management within the meeting, meeting sharing whiteboards, meeting group chat, contact management, account management. In summary, through the use of the software, users no longer need to sit in the conference room or computer, you can hold board meetings at anytime in anywhere, and communicate and collaborate with your partners remotely.
