到xmpp的连接给出套接字异常（权限被拒绝）

Question

我正在尝试通过我的android应用程序使用smack库连接到openfire服务器。当我连接到服务器时，它给我和错误

以下地址失败：“192.168.0.31:5222”失败，因为java.net.SocketException：套接字失败：EACCES（拒绝权限）

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;

}

从我的登录活动调用SmackConnection.init（用户，密码）；它给出java.net.SocketException权限被拒绝的错误。

错误日志如下所示。

Answer 1

希望您的清单中没有使用权限INTERNET。

<uses-permission android:name="android.permission.INTERNET"></uses-permission>
