Android 在使用 Jain-SIP 库创建 SipStack 时出错

【中文标题】Android 在使用 Jain-SIP 库创建 SipStack 时出错

【英文标题】：Android gives error when creating SipStack using Jain-SIP library

【发布时间】：2019-12-01 10:02:51

【问题描述】：

在 android studio 中，我的代码一旦到达以下行就会失败。

sipStack = sipFactory.createSipStack(properties);

它给了我以下错误。

W/System.err: android.javax.sip.PeerUnavailableException: The Peer SIP Stack: gov.nist.javax.sip.SipStackImpl could not be instantiated. Ensure the Path Name has been set.
...
Caused by: java.lang.NoSuchMethodException: gov.nist.javax.sip.SipStackImpl.<init> [class java.util.Properties]

您知道导致此错误的原因吗？

我正在为 Jain-SIP 使用以下依赖项。

compile group: 'javax.sip', name: 'android-jain-sip-ri', version: '1.3.0-91'

代码在 IntelliJ 中运行没有问题。 我正在使用带有 Ubuntu 18.04.2 LTS 的 Android Studio。

---

我的 MainActivity 类如下。

public class MainActivity extends AppCompatActivity 

    @Override
    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        new Shootist().init();
    

我的 Shootist 课程如下。

public class Shootist implements SipListener 

    public void init() 
        SipFactory sipFactory = SipFactory.getInstance();
        sipFactory.setPathName("gov.nist");
        SipStack sipStack = null;

        String transport = "udp";
        String peerHostPort = "127.0.01:5070";

        Properties properties = new Properties();
        properties.setProperty("android.javax.sip.OUTBOUT_PROXY", peerHostPort + "/" + transport);
        properties.setProperty("android.javax.sip.STACK_NAME", "shootist");
        properties.setProperty("gov.nist.javax.sip.DEBUG_LOG", "shootistdebug.txt");
        properties.setProperty("gov.nist.javax.sip.TRACE_LEVEL", "DEBUG");

        System.out.println("trying to create sip stack");
        // create sip stack
        try 
            sipStack = sipFactory.createSipStack(properties);
            System.out.println("sip stack created");

         catch (PeerUnavailableException e) 
            e.printStackTrace();
        



    

    @Override
    public void processRequest(RequestEvent requestEvent) 

    

    @Override
    public void processResponse(ResponseEvent responseEvent) 

    

    @Override
    public void processTimeout(TimeoutEvent timeoutEvent) 

    

    @Override
    public void processIOException(IOExceptionEvent exceptionEvent) 

    

    @Override
    public void processTransactionTerminated(TransactionTerminatedEvent transactionTerminatedEvent) 

    

    @Override
    public void processDialogTerminated(DialogTerminatedEvent dialogTerminatedEvent) 

    

整个错误输出如下。

【参考方案1】：

主要问题是

sipFactory.setPathName("gov.nist");

应该是

sipFactory.setPathName("android.gov.nist");

初始化与android略有不同。也许你可以从这个例子开始 https://github.com/usnistgov/jsip/tree/master/src/examples/android/simplecallsetup 并在它之上构建。

【讨论】：

这实际上是我正在尝试构建的示例。该示例在我运行时似乎不起作用，因此我试图通过从头开始处理它来找出问题所在。哦，谢谢你的回答；解决了这个问题。
