android：无法创建与 openfire 的连接
android : cannot create connection to openfire
我正在尝试在 ConnectionAsyncTask class 中创建连接以开火。
我正在使用 Smack 库 v4.13
代码如下：
public class ConnectionAsyncTask extends AsyncTask<Void, Void, Void> {
public ConnectionAsyncTask() {
}
@Override
protected Void doInBackground(Void... params) {
XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration.builder();
config.setServiceName(HOST);
config.setHost(HOST);
config.setPort(PORT);
config.setDebuggerEnabled(true);
mConnection = new XMPPTCPConnection(config.build());
try {
mConnection.connect();
Log.i("connect", "connected");
} catch (SmackException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (XMPPException e) {
e.printStackTrace();
}
return null;
}
}
但是上面的代码抛出以下错误：

注意：我在我的项目中包含了列出的所有库 JAR Files and Requirements。
我不知道它对我有什么帮助..但是，包括下面几行 build.gradle 解决了我的问题：
compile "org.igniterealtime.smack:smack-android:4.1.3"
compile "org.igniterealtime.smack:smack-bosh:4.1.3"
compile "org.igniterealtime.smack:smack-tcp:4.1.3"
compile "org.igniterealtime.smack:smack-im:4.1.3"
compile "org.jxmpp:jxmpp-jid:0.5.0-alpha6"
compile "org.igniterealtime.smack:smack-extensions:4.1.3"
我不知道这背后的原因。如果有人知道原因，欢迎您编辑和更新我的答案。
现在我是这样建立联系的：
public class MyAsyncTask extends AsyncTask<Void, Void, Void> {
@Override
protected Void doInBackground(Void... params) {
// Create a connection to the jabber.org server on a specific port.
XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()
.setServiceName("my-ip")
.setHost("my-ip")
.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
.setPort(5222)
.setDebuggerEnabled(true)
.build();
AbstractXMPPConnection conn2 = new XMPPTCPConnection(config);
try {
conn2.connect();
Log.i("connecting: ", "Connected");
} catch (SmackException | XMPPException | IOException e) {
e.printStackTrace();
}
return null;
}
}
还是谢谢你。
我有同样的错误。
我的依赖项是：
compile "org.igniterealtime.smack:smack-android:4.1.7"
compile "org.igniterealtime.smack:smack-tcp:4.1.7"
compile "org.igniterealtime.smack:smack-im:4.1.7"
compile "org.igniterealtime.smack:smack-extensions:4.1.7"
我认为这与 JavaxResolver 有关，请参阅此 thread。
一旦我添加了以下依赖项：
compile "org.igniterealtime.smack:smack-bosh:4.1.7"
错误消失了。
希望对您有所帮助！
