java - 使用 Android SIP 堆栈注册 SIP 配置文件

Question

我一直在开发一个应用程序，该应用程序能够让用户使用 SIP 调用和接听电话，灵感来自 SIPDemo，其中直到我从手机上卸载该应用程序为止，它都工作正常，它完成了注册，显示了消息“准备好”，然后继续进行调用处理。现在它不会进入 Sipregistrationlistener，并显示错误“尝试关闭管理器 1 SipException 时出错:无法创建 SipSession；网络不可用？”。

据我了解，我怀疑问题是由于之前的 SIP 帐户仍然链接，因此在应用程序中自动打开，不允许任何注册，如本文解决方案“Android Native SIP Stack not registering client”中所述。 ”，但我不知道如何处理这个问题，在 onDestroy、onPause 上引入 closelocalprofile 函数没有效果。此外，直到最近它确实显示了消息“SipManager 已准备好调用”并且它已打开，但现在尽管没有更改代码中的任何内容，但它却没有显示，因此问题可能不一定是这个。

在打印方面，显示以下消息:- 不显示与状态相关的消息；-日志显示“创建管理器”和“构建新配置文件”；

此外，我已经拥有支持 SIP 通信的权限和 list 编码。

我现在知道这个堆栈不是最好的，但我不想放弃这个项目，所以任何帮助或提示将不胜感激。在最后一种情况下，在准备过程中，如果没有找到解决方案/进展，如果你们中的任何人也可以推荐类似的替代堆栈，我们也将不胜感激。

这是代码:

public SipManager sipManager = null;//SIPMANAGER
public SipProfile sipProfile = null;//SIPPROFILE
public SipAudioCall call = null;//SIPAUDIOCALL
public IncomingCallReceiver callReceiver;

@Override
protected void onCreate(Bundle savedInstanceState)
{
    Permissions();
    Supported();

    initManager();

    MakeCallButton.setOnClickListener(new View.OnClickListener() /onclick event
    {
        @Override
        public void onClick(View view)
        {
           initCall();
        }
    });
    EndCallButton.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View view) {
            try
            {
                call.endCall();
            }
            catch (SipException e)
            {
                status("Error when trying to end call. " + e);
            }
        }
    });
}

public void initManager()//SIPMANAGER
{
    if(sipManager == null)
    {
        sipManager = SipManager.newInstance(this); //Creates a manager instance. Returns null if SIP API is not supported
        Log.d("Manager", "Creating Manager");
    }

       sipProfile = builder.build();//Builds and returns the SIP profile object.

       Intent sipIntent = new Intent();//intent for the calls
       sipIntent.setAction("android.Login.INCOMING_CALL");
       PendingIntent pi = PendingIntent.getBroadcast(this, 0, sipIntent, Intent.FILL_IN_DATA);
       sipManager.open(sipProfile, pi, null);//Opens the profile for making calls and/or receiving generic SIP calls

       //Sets the listener to listen to registration events. No effect if the profile has not been opened to receive call

更新

通过重新安装应用程序后重新启动设备以及将代码从 Android Studio 重新发送到手机相结合，成功解决了以前的这些错误。正如我上面所说，我对错误来源的怀疑是由于该堆栈存在错误，但它现在可以工作，并且我对成品感到满意。

尽管这里没有得到任何回复，但我希望这个帖子可以对某人有所帮助。
