使用Sinch即時消息系統

Question

我正在將Sinch和Parse用於集成在應用程序中的即時消息傳遞系統，但有兩個問題。

1）由於某種原因，當顯示消息活動時，我收到以下錯誤消息：“消息客戶端未啟動”。此外，消息似乎沒有在Sinch中通過，也沒有在應用程序中直觀地反映出來。

下面是活動代碼（當用戶單擊“快速聊天”按鈕時，它將帶他們到消息傳遞活動頁面。

以下是消息傳遞活動的活動代碼

public class MessagingActivity extends Activity implements ServiceConnection, MessageClientListener {

    private String recipientId;
    private Button sendButton;
    private EditText messageBodyField;
    private String messageBody;
    private MessageService.MessageServiceInterface messageService;
    private MessageAdapter messageAdapter;
    private ListView messagesList;

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

        doBind();


        messagesList = (ListView) findViewById(R.id.listMessages);
        messageAdapter = new MessageAdapter(this);
        messagesList.setAdapter(messageAdapter);

        Intent intent = getIntent();
        recipientId = intent.getStringExtra("Name");

        messageBodyField = (EditText) findViewById(R.id.messageBodyField);
        sendButton = (Button) findViewById(R.id.sendButton);

        sendButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                sendMessage();
            }
        });
    }

    private void sendMessage() {
        messageBodyField = (EditText) findViewById(R.id.messageBodyField);
        messageBody = messageBodyField.getText().toString();
        if (messageBody.isEmpty()) {
            Toast.makeText(this, "Please enter a message", Toast.LENGTH_LONG).show();
            return;
        }

        //Here is where you will actually send the message throught Sinch
        messageService.sendMessage(recipientId, messageBody);
        messageBodyField.setText("");
    }

    private void doBind() {
        Intent serviceIntent = new Intent(this, MessageService.class);
        bindService(serviceIntent, this, BIND_AUTO_CREATE);
    }

    @Override
    public void onDestroy() {
        unbindService(this);
        super.onDestroy();
    }

    @Override
    public void onServiceConnected(ComponentName componentName, IBinder iBinder) {
        //Define the messaging service and add a listener
        messageService = (MessageService.MessageServiceInterface) iBinder;
        messageService.addMessageClientListener(this);
        if (!messageService.isSinchClientStarted()) {
            Toast.makeText(this, "The message client did not start."
                ,Toast.LENGTH_LONG).show();
        }
    }

    @Override
    public void onServiceDisconnected(ComponentName componentName) {
        messageService = null;
    }

    @Override
    public void onMessageDelivered(MessageClient client, MessageDeliveryInfo deliveryInfo) {
        //Intentionally  left blank
    }

    @Override
    public void onMessageFailed(MessageClient client, Message message,
                                MessageFailureInfo failureInfo) {
        //Notify the user if message fails to send
        Toast.makeText(this, "Message failed to send.", Toast.LENGTH_LONG).show();
    }

    @Override
    public void onIncomingMessage(MessageClient client, Message message) {
        messageAdapter.addMessage(message, MessageAdapter.DIRECTION_INCOMING);
    }

    @Override
    public void onMessageSent(MessageClient client, Message message, String recipientId) {
        messageAdapter.addMessage(message, MessageAdapter.DIRECTION_OUTGOING);
    }

    @Override
    public void onShouldSendPushData(MessageClient client, Message message, List<PushPair> pushPairs) {
        //Intentionally left blank
    }
}

我已驗證APP_KEY，APP_SECRET和ENVIRONMENT是否與Sinch上記錄的內容匹配。 我在模擬器和物理設備上都嘗試過此操作。

提前致謝

2）限制：我想設置一個限制，特定方之間只有25條消息可用。

預先感謝您，如果您需要任何澄清，請告訴我。

Answer 1

我寫了您要遵循的教程，實際上昨天才對其進行了更新，以解決您的第一個問題。 查看http://tutorial.sinch.com/android-messaging-tutorial/#show-spinner以查看更新。 在服務未啟動時，新版本將不顯示提示消息，而是顯示進度對話框（正在加載微調器），直到服務已啟動或無法啟動為止。

您能澄清第二個問題嗎？

只需在清單中聲明您的服務即可。 我有同樣的問題，它解決了。
