我正在尝试使用smack库通过我的Android应用程序连接到openfire服务器。当我连接到服务器时它给了我和错误
以下地址失败：'192.168.0.31:5222'失败，因为java.net.SocketException：套接字失败：EACCES（权限被拒绝）
但是我已经在我的清单中获得了互联网许可。
我正在使用的代码是..
public void init(String mUsername, String mPassword) {
Log.i(TAG, "connect()");
config = XMPPTCPConnectionConfiguration.builder();
config.setServiceName(mServiceName);
config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
config.setHost(mServiceName);
config.setPort(5222);
config.setDebuggerEnabled(true);
config.setResource("sender");
// config.setCompressionEnabled(true);
config.setUsernameAndPassword(mUsername, mPassword);
XMPPTCPConnection.setUseStreamManagementResumptiodDefault(true);
XMPPTCPConnection.setUseStreamManagementDefault(true);
mConnection = new XMPPTCPConnection(config.build());
mConnection.addConnectionListener(this);
ChatManager.getInstanceFor(mConnection).addChatListener(this);
gson = new Gson();
connectAndLoginAnonymously();
}
public void connectAndLoginAnonymously() {
mRegisterTask = new AsyncTask<Void, Void, Void>() {
@Override
protected Void doInBackground(Void... params) {
try {
mConnection.connect();
DeliveryReceiptManager dm = DeliveryReceiptManager
.getInstanceFor(mConnection);
dm.setAutoReceiptMode(DeliveryReceiptManager.AutoReceiptMode.always);
dm.addReceiptReceivedListener(new ReceiptReceivedListener() {
@Override
public void onReceiptReceived(final String fromid,
final String toid, final String msgid,
final Stanza packet) {
}
});
mConnection.login();
} catch (SmackException | XMPPException | IOException e) {
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Void res) {
}
};
// execute AsyncTask
mRegisterTask.execute();
}
public void disconnect() {
Log.i(TAG, "disconnect()");
if (mConnection != null) {
mConnection.disconnect();
}
}
//For Creating new User.
public boolean createNewAccount(String username, String newpassword) {
boolean status = false;
if (mConnection == null) {
try {
mConnection.connect();
} catch (SmackException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (XMPPException e) {
e.printStackTrace();
}
}
try {
// String newusername = username + mConnection.getServiceName();
Log.i("service", mConnection.getServiceName());
AccountManager accountManager = AccountManager.getInstance(mConnection);
accountManager.createAccount(username, newpassword);
status = true;
} catch (SmackException.NoResponseException e) {
status = false;
e.printStackTrace();
} catch (XMPPException.XMPPErrorException e) {
e.printStackTrace();
status = false;
} catch (SmackException.NotConnectedException e) {
e.printStackTrace();
status = false;
}
mConnection.disconnect();
return status;
}
从我的登录活动中，当我打电话 smackConnection.init（用户，密码）; 它给了我 java.net.SocketException权限被拒绝的错误。
错误日志如下。
