通过Android连接到Openfire服务器

Question

我正在尝试使用以下代码连接到正在运行的Openfire服务器：

public static final String HOST = "ipofmyserver";
public static final int PORT = 9122;  // set by me
//public static final String SERVICE = "gmail.com"; not used because i don't know what it refers to

ConnectionConfiguration connConfig = new ConnectionConfiguration(HOST, PORT);
XMPPConnection connection = new XMPPConnection(connConfig);

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

    //Connect to the server
    try {
        connection.connect();
    } catch (XMPPException e) {
        connection = null;
        //Unable to connect to server
    }

    //Most servers require you to login before performing other tasks.
    if (connection != null) {
        try {
            connection.login("xxxx", "xxxx");
        } catch (XMPPException e) {
            e.printStackTrace();
        }
    }
}

logcat的

我添加了一个exceptionininitializer异常，现在它不会崩溃，但是现在我得到了：

05-07 03:27:55.734    3184-3184/xxx.xxx.xxxxxE/dalvikvm﹕ Could not find class 'javax.naming.directory.InitialDirContext', referenced from method org.jivesoftware.smack.util.dns.JavaxResolver.<clinit>

UPDATE

我了解到，Android仅允许访问某些标准JRE类，这些类在此白名单中https://developers.google.com/appengine/docs/java/jrewhitelist

所以..如果我想使用Smack api，该怎么办？ 我不能吗 我尝试了aSmack，但必须在linux或mac上编译，而且我只有Windows

Answer 1

请如果您使用的是smack api，则还必须与此API一起使用xpp.jar到您的项目中。 我也遇到了同样的问题，并使用此api解决了这个问题。

这是该api的链接。 Xpp下载链接

在Android Studio Gradle中，依赖项对我有用：

dependencies {
  compile 'org.igniterealtime.smack:smack-android:4.1.1'
  compile 'org.igniterealtime.smack:smack-android-extensions:4.1.1'
