Android的SipManager扔NullPointException [英] Android SipManager throwing NullPointException

问题描述

我想实现我自己的Andr​​oid SiP实现，我有我的SIP服务器注册的问题。具体来说，SipManager.register（）函数抛出一个NullPointerException异常。有没有人经历过这个？有没有什么是在下面的函数空，所以我不明白的地方这是来自。谢谢

 公共布尔initializeProfile（）{
    最终的全局全球= Globals.getInstance（）;
    如果（sipProfile！= NULL）
        closeLocalProfile（）;    字符串username =忽略;
    字符串密码=忽略;
    字符串服务器=忽略;    尝试{
        global.Log（试图建立配置文件）;
        SipProfile.Builder建设者=新SipProfile.Builder（用户名，
                服务器）;
        builder.setPassword（密码）;
        sipProfile = builder.build（）;
        builder.setAutoRegistration（真）;        sipManager.open（sipProfile）;        思pregistrationListener监听器=新思pregistrationListener（）{            公共无效onRegistering（字符串localProfileUri）{
                global.Log（SIP Listener-试图注册）;
            }            公共无效onRegistrationDone（字符串localProfileUri，
                    长expiryTime）{
                global.Log（SIP Listener-注册成功！）;
            }            公共无效onRegistrationFailed（字符串localProfileUri，
                    INT错误code，弦乐的errorMessage）{
                global.Log（SIP Listener-注册失败）;
            }
        };        sipManager.setRegistrationListener（sipProfile.getUriString（），监听器）;        //这是在异常被抛出
        sipManager.register（sipProfile，3000，监听器）;        如果（sipManager.isRegistered（sipProfile.getUriString（）））
        {
            global.Log（SipManager准备调用）;
            返回true;
        }
        其他
            返回false;    }赶上（例外前）{            global.Log（--- Error-- initializeProfile：+ ex.getMessage（））;
            返回false;    }}
 

解决方案

解决我自己的问题。似乎这不工作，而相当不错，在一个线程中运行。

I'm trying to implement my own android sip implementation and I am having problems registering with my SIP server. Specifically, the SipManager.register() function is throwing a NullPointerException. Has anybody experienced this before? There isn't anything that is null in the below function so I don't understand where this is coming from. Thanks

public boolean initializeProfile() {
    final Globals global = Globals.getInstance();
    if (sipProfile != null)
        closeLocalProfile();

    String username = "omitted";
    String password = "omitted";
    String server = "omitted";

    try {
        global.Log("Trying to build the profile");
        SipProfile.Builder builder = new SipProfile.Builder(username,
                server);
        builder.setPassword(password);
        sipProfile = builder.build();


        builder.setAutoRegistration(true);

        sipManager.open(sipProfile);

        SipRegistrationListener listener = new SipRegistrationListener() {

            public void onRegistering(String localProfileUri) {
                global.Log("Sip Listener- Attempting to Register");
            }

            public void onRegistrationDone(String localProfileUri,
                    long expiryTime) {
                global.Log("Sip Listener- Registration Success!");
            }

            public void onRegistrationFailed(String localProfileUri,
                    int errorCode, String errorMessage) {
                global.Log("Sip Listener- Registration Failed");
            }
        };

        sipManager.setRegistrationListener(sipProfile.getUriString(), listener);

        //THIS IS WHERE THE EXCEPTION IS BEING THROWN
        sipManager.register(sipProfile, 3000, listener);

        if (sipManager.isRegistered(sipProfile.getUriString()))
        {
            global.Log("SipManager is ready for calls");
            return true;
        }
        else
            return false;

    } catch (Exception ex) {

            global.Log("---Error-- initializeProfile: " + ex.getMessage());
            return false;

    }

}

解决方案

Solved my own problem. Seems that this doesn't work very well while running in a thread.
