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]
您知道可能导致此错误的原因吗？
<小时/>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 Android Studio 和 Ubuntu 18.04.2 LTS。
<小时/>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 类(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) {
}
}

最佳答案
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并建立在其之上。
