我在过去的四天里尝试使用自己的XMPP和Smack + OpenFire发送和接收聊天消息。据Smack＆＃34; readme.txt＆＃39;我设置连接并登录用户。连接和登录的代码是这个
public static String TAG = "Test connection";
private static XMPPTCPConnection connection;
private static String userName = "demo";
private static String Password = "demo";
static {
// Create the configuration for this new connection
XMPPTCPConnectionConfiguration.Builder configBuilder = XMPPTCPConnectionConfiguration.builder();
configBuilder.setSecurityMode(XMPPTCPConnectionConfiguration.SecurityMode.disabled);
configBuilder.setResource("");
configBuilder.setUsernameAndPassword(userName, Password);
configBuilder.setServiceName("192.168.2.10");
configBuilder.setHost("192.168.2.10");
configBuilder.setPort(5222);
configBuilder.setCompressionEnabled(false);
connection = new XMPPTCPConnection(configBuilder.build());
}
这样我配置了connectionbuilder。 在这里，我正在连接并登录用户。
public class ConnectAndLogin extends AsyncTask<Void, Void, Void> {
@Override
protected Void doInBackground(Void... params) {
try {
connection.connect();
Log.i(TAG, "Connected to " + connection.getHost());
} catch (SmackException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (XMPPException e) {
Log.e(TAG, "Failed to connect to " + connection.getHost());
Log.e(TAG, e.toString());
e.printStackTrace();
}
try {
connection.login(userName, Password);
Log.i(TAG, "Login as a : " + connection.getUser());
setConnection(connection);
setListner();
} catch (XMPPException e) {
e.printStackTrace();
Log.i(TAG, "Login error " + e.toString());
} catch (SmackException e) {
e.printStackTrace();
Log.i(TAG, "Login error " + e.toString());
} catch (IOException e) {
e.printStackTrace();
Log.i(TAG, "Login error " + e.toString());
}
return null;
}
}
在某些教程中，必须在登录后设置addPacketListner。我在setConnection()完成了这项工作，有些帖子经历了addAsyncStanzaListner。
发送消息
send.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Message msg = new Message("demo2", Message.Type.chat);
msg.setBody("Hi how are you");
if (connection != null) {
try {
connection.sendPacket(msg);
Log.d("Send to room : Name : ", "demo2");
Log.d("store", "store data to db");
//DBAdapter.addUserData(new UserData(text, "", "1" ,beam_id));
} catch (Exception e) {
Log.d("ooo", "msg exception" + e.getMessage());
}
}
}
});
以及接收消息此代码
public void setListner() {
connection.addAsyncStanzaListener(new StanzaListener() {
@Override
public void processPacket(Stanza packet) throws SmackException.NotConnectedException {
Message message = (Message) packet;
Log.i(TAG, "REC : " + message.getBody());
Log.i(TAG, "REC: " + message.getFrom());
}
}, new StanzaFilter() {
@Override
public boolean accept(Stanza stanza) {
return false;
}
});
}
这是我的依赖
compile 'org.igniterealtime.smack:smack-android:4.1.0'
compile 'org.igniterealtime.smack:smack-tcp:4.1.0'
compile 'org.igniterealtime.smack:smack-core:4.1.0'
compile 'org.igniterealtime.smack:smack-im:4.1.0'
compile 'org.igniterealtime.smack:smack-resolver-minidns:4.1.0'
compile 'org.igniterealtime.smack:smack-sasl-provided:4.1.0'
但我仍然无法向demo2用户发送消息。 我做错了。请指导和帮助我。 感谢

很长一段时间后，我可以发送短信甚至图像。这是我处理XmppConnection的完整代码。
