Android 使用 Jain-SIP 库创建 SipStack 时出错

Question

在 android studio 中，我的代码一到下一行就失败了。

sipStack = sipFactory.createSipStack(properties);

它给我以下错误。

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]

您知道可能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中没有问题运行。我正在使用 Android Studio 和 Ubuntu 18.04.2 LTS。

我的MainActivityclass如下

public class MainActivity extends AppCompatActivity {

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

我的射手class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) {

    }
}

完整的错误输出如下。

Answer 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。或许您可以从这个示例开始 https://github.com/usnistgov/jsip/tree/master/src/examples/android/simplecallsetup 并在此基础上构建。
