所以这是我的问题：我使用我的令牌生成了一个 ChatClient 实例，我想加入一个接收到的 SID 不成功的实例，我收到以下错误

我从 twilio 网站开始使用 twilio chat quickstart android。我还创建了访问令牌 url 来检索令牌。下面是我用于 twilio 聊天集成的主要活动代码。

public class MainActivity extends AppCompatActivity {

/*
   Change this URL to match the token URL for your Twilio Function
*/
final static String SERVER_TOKEN_URL = "https://example.com/chat-token";

final static String DEFAULT_CHANNEL_NAME = "general";
final static String TAG = "TwilioChat";

// Update this identity for each individual user, for instance after they login
private String mIdentity = "CHAT_USER";

private RecyclerView mMessagesRecyclerView;
private MessagesAdapter mMessagesAdapter;
private ArrayList<Message> mMessages = new ArrayList<>();

private EditText mWriteMessageEditText;
private Button mSendChatMessageButton;

private ChatClient mChatClient;

private Channel mGeneralChannel;


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

    mMessagesRecyclerView = (RecyclerView) findViewById(R.id.messagesRecyclerView);

    LinearLayoutManager layoutManager = new LinearLayoutManager(this);
    // for a chat app, show latest at the bottom
    layoutManager.setStackFromEnd(true);
    mMessagesRecyclerView.setLayoutManager(layoutManager);

    mMessagesAdapter = new MessagesAdapter();
    mMessagesRecyclerView.setAdapter(mMessagesAdapter);

    mWriteMessageEditText = (EditText) findViewById(R.id.writeMessageEditText);

    mSendChatMessageButton = (Button) findViewById(R.id.sendChatMessageButton);
    mSendChatMessageButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if (mGeneralChannel != null) {
                String messageBody = mWriteMessageEditText.getText().toString();
                Message.Options options = Message.options().withBody(messageBody);
                Log.d(TAG,"Message created");
                mGeneralChannel.getMessages().sendMessage(options, new CallbackListener<Message>() {
                    @Override

嘿，我在设置 Twilio 演示聊天应用程序时也遇到了这个问题。我正在使用https://github.com/twilio/twilio-chat-demo-android android 应用程序和https://github.com/TwilioDevEd/sdk-starter-ruby。我花了一点时间才发现我ACCESS_TOKEN_SERVICE_URL=http://abc12345.ngrok.io只是从复制粘贴 ngrok 到我的 kotlin 应用程序gradle.properties文件中设置的。当我应该查看 sdk-starter-ruby 应用程序中定义的路由时。在这种情况下，sinatra 应用程序定义了一条路线

get '/token' do
  # Create a random username for the client
  identity = Faker::Internet.user_name

  # Create an access token which we will sign and return to the client
  token = generate_token(identity)

  # Generate the token and send to client
  json :identity => identity, :token => token
end

这是我需要作为该属性的 URL 输入的路由。所以这为我解决了这个问题ACCESS_TOKEN_SERVICE_URL=http://abc12345.ngrok.io/token

您SERVER_TOKEN_URL的 tohttps://example.com/chat-token应该指向生成令牌的服务器。这里有多种语言的示例：https ://www.twilio.com/docs/chat/javascript/quickstart
