linphone-LinphoneManager.java文件分析

介绍

本篇主要是对个人对LinphoneManger类的理解及对上面的注释,这是对linphone研究的一个开始. 会慢慢对linphone逐步分析, 随着时间的推进, 我会对linphone有进一步的了解,希望希望了解的同学能跟上我的脚步.

简介

LinphoneManager类是Linphone的主要操作管理类.

主要功能:

官方

/**** Manager of the low level LibLinphone stuff.<br />* Including:<ul>* <li>Starting C liblinphone</li>* <li>Reacting to C liblinphone state changes</li>* <li>Calling Linphone android service listener methods</li>* <li>Interacting from Android GUI/service with low level SIP stuff/</li>* </ul>** Add Service Listener to react to Linphone state changes.** @author Guillaume Beraudo**/

大致意思是:

管理linphone核心类的操作文件
加载c文件的类库
进行c库的状态交互
回调linphone方法
与界面和后台服务进行交互

个人理解
1. 通过LinphoneFactory进行c库文件的加载.
2. 对基础文件进行加载及使用.
3. 对于聊天信息,及传输文件信息类的管理类的操作
4. 对于接打电话及视频的操作.
5. 判断linphone的在线状态.但是好像并不是很完全.
6. 显示接打电话的名称.
7. 设置及判断信道, video编码格式,audio编码格式等.
8. 开启Tunnel的服务类(好像是, 并不太清楚)
9. 对于linphone服务的保活类.
10. 将package中的文件存储到assets文件夹中.
11. 更新并判断网络状态
12. 对于dmtf的管理
13. 设置接听电话的
14. 音量的配置
15.
