Question

在过去的几天里，我试图让JAIN SIP在Android上运行。我采用了一些在Java应用程序上运行良好的代码，并将其移植到Android应用程序中。

我查了一下：

清单中的权限（INTERNET / ALL）
JAIN SIP API工作正常（stackoverflow上的其他线程重点关注）。
通信在自己的线程上运行，而不是MainThread。
IP有效。
如果我没有使用Android作为平台而是使用Ubuntu，则代码可以正常运行。
我尝试过Android 4.0.3及更高版本。

我的代码：

public class MainActivity extends Activity implements SipListener {

private static final String LOG = "JAIN";
private static final int PORT = 5060;
private SipFactory mSipFactory;
private AddressFactory mAddressFactory;
private MessageFactory mMessageFacory;
private HeaderFactory mHeaderFactory;
private SipStack mSipStack;
private SipProvider mSipProvider;

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

    new Thread(new Runnable(){

        @Override
        public void run() {
            try {
                // Create factories
                mSipFactory = SipFactory.getInstance();
                mAddressFactory = mSipFactory.createAddressFactory();
                mMessageFacory = mSipFactory.createMessageFactory();
                mHeaderFactory = mSipFactory.createHeaderFactory();

                // Create the SipStack
                Properties properties = new Properties();
                properties.setProperty("javax.sip.STACK_NAME","Stack");
                mSipStack = mSipFactory.createSipStack(properties);

                // Create the SipProvider 
                String localIP = InetAddress.getLocalHost().getHostAddress();
                ListeningPoint listeningPoint = mSipStack
                        .createListeningPoint(localIP, PORT, "udp");
                mSipProvider = mSipStack.createSipProvider(listeningPoint);
                mSipProvider.addSipListener(MainActivity.this);

                // Create addresses and via header for the request
                Address fromToAddress = mAddressFactory
                        .createAddress("sip:192.168.0.198");
                Address contactAddress = mAddressFactory
                        .createAddress("sip:me@192.168.0.195");
                ArrayList<ViaHeader> viaHeaders = new ArrayList<ViaHeader>();
                ViaHeader myViaHeader = mHeaderFactory
                        .createViaHeader("me.bla.com", PORT, "udp", "tlf64");
                viaHeaders.add(myViaHeader);

                // Build the request
                final Request request = mMessageFacory.createRequest(
                        mAddressFactory.createAddress("sip:192.168.0.195:9876").getURI(), 
                        "REGISTER",
                        mHeaderFactory.createCallIdHeader("12345678"),
                        mHeaderFactory.createCSeqHeader(1234l, "REGISTER"), 
                        mHeaderFactory.createFromHeader(fromToAddress, "sdf6"),
                        mHeaderFactory.createToHeader(fromToAddress, null), 
                        viaHeaders, 
                        mHeaderFactory.createMaxForwardsHeader(70));

                // Add the contact header
                request.addHeader(mHeaderFactory.createContactHeader(contactAddress));

                // Print the request
                System.out.println(request.toString());

                // Send the request --- triggers an IOException
                mSipProvider.sendRequest(request);
            } catch (Exception e) {
                Log.d(LOG, Log.getStackTraceString(e));
            }
        }}).start();
}

正如您在StackTrace中看到的，发生IOException：

java.net.SocketException: sendto failed: EINVAL (Invalid argument)

在具有相同参数的Ubuntu上不会抛出

。

有任何想法如何修复它？非常感谢您的帮助！

Answer 1

似乎Android OS以与Ubuntu OS不同的方式处理给定的Strings。我不知道为什么。

毕竟，我通过使用MjSip而不是JAIN SIP来解决问题。

由于我需要RTP，SDP以及SIP旁边的一些东西，我决定修改使用MjSip 1.6的开源Android App Sipdroid，直到它符合我的要求。

为此，请先获取code。
将项目导入Eclipse：文件 - ＆gt;导入 - ＆gt;现有的Android代码进入工作区。
根据API等级创建一个满足您需求的新Android项目。
将<uses-permission android:name="android.permission.INTERNET" />添加到项目的清单中。
将Sipdroid项目中的以下所有软件包复制到您的项目中：
- org.sipdroid.codecs和org.sipdroid.media（我不需要，也许以后）
- org.sipdroid.sipua和subpackages。
删除或评论损坏的参考文献。
请参阅以下代码，将REGISTER发送到服务器。
使用android.util.Log而不是给定代码修复Log机制抛出的Exeptions。最后，删除或注释触发NullPointerException的flush命令。

就是这样。

            try{
                SipStack.init();

                SipProvider sipProvider = new SipProvider(
                        "192.168.0.198", 5060, new String[]{"udp"}, null);
                NameAddress toAddress = new NameAddress(

Answer 2

而不是将localIPAddress取为：

String localIP = InetAddress.getLocalHost().getHostAddress();

使用NetworkInterface或WifiManager

获取IP地址
