一、WelcomeFragment:用戶注冊(cè)選擇登錄服務(wù)器
AssistantActivity(處理用戶注冊(cè)界面)->WelcomeFragment(用于登錄方式，包括：創(chuàng)建用戶、利用LinPhone賬號(hào)、SIP賬號(hào)、獲取遠(yuǎn)程配置)

2.3、利用LinPhone賬號(hào)(Use SIP account)

實(shí)際這個(gè)界面所做的業(yè)務(wù)，主要通過(guò)AssistantActivity.java 的public void saveCreatedAccount(String username, String userid, String password, String displayname, String ha1, String prefix, String domain, TransportType transport)方法實(shí)現(xiàn)。

三、跟蹤注冊(cè)流程

Java： LoginFragment ----(調(diào)用)---->AssistantActivity(方法：genericLogIn-(調(diào)用)->saveCreatedAccount)-(調(diào)用)->AccountBuilder(方法：saveNewAccount)---(調(diào)用)-->LinphoneCore(Jni方法)
saveNewAccount方法中的添加用戶信息到LinphoneCore

//只是將傳入的cfg追加到lc->sip_conf.proxies列表中存儲(chǔ)起來(lái)； 然后通過(guò)linphone_proxy_config_apply(cfg，lc）存儲(chǔ)起來(lái);
lc.addProxyConfig(prxCfg);
 //登陸的賬號(hào)信息保存
 lc.addAuthInfo(authInfo);

發(fā)送注冊(cè)：LinphoneManager(mLc.iterate())

 private synchronized void startLibLinphone(Context c) {

        //traces alway start with traces enable to not missed first initialization
        mLc = LinphoneCoreFactory.instance().createLinphoneCore(this, mLinphoneConfigFile, mLinphoneFactoryConfigFile, null, c);
        TimerTask lTask = new TimerTask() {
            @Override
            public void run() {
                UIThreadDispatcher.dispatch(new Runnable() {
                    @Override
                    public void run() {
                        if (mLc != null) {

        mTimer = new Timer("Linphone scheduler");
        mTimer.schedule(lTask, 0, 20);
    } catch (Exception e) {

開(kāi)啟創(chuàng)建Linphone的核心時(shí)就應(yīng)經(jīng)開(kāi)始了定時(shí)的去處理Linphone的sip指令，那么我們看一下iterate做了一些啥？
跟蹤流程：調(diào)用LinphoneCoreImpl中的private native void iterate(long nativePtr)其中nativePtr是LinphoneCore

Jni：linphonecore_jni.cc

  extern "C" void Java_org_linphone_core_LinphoneCoreImpl_iterate(JNIEnv* env
    ,jobject  thiz
    ,jlong lc) {
linphone_core_iterate((LinphoneCore*)lc);}

實(shí)際上是調(diào)用void linphone_core_iterate(LinphoneCore *lc)：
這個(gè)函數(shù)是linphone的核心功能，在這個(gè)循環(huán)內(nèi)，主要進(jìn)行的操作有，接收sip消息、處理定時(shí)器、處理proxy的注冊(cè)狀態(tài)變化、認(rèn)證重連；
關(guān)于登錄的處理是通過(guò)proxy_update(lc)實(shí)現(xiàn)的

至此登錄流程不在深究：后續(xù)繼續(xù)補(bǔ)充
