我将 Sinch 和 Parse 用于集成在我们的应用程序中的即时消息系统。出于某种原因，当显示消息活动时，我收到以下错误：消息客户端没有启动“。此外，消息似乎没有在 Sinch 中通过，也没有在应用程序中直观地反映。
下面是活动代码（当用户单击“快速聊天”按钮时，它会将他们带到消息传递活动页面。
public class matchOptionActivity extends Activity{
protected TextView mUserRetrieved;
private String currentUserId;
protected TextView mUserActivityNameRetrieved;
protected TextView mUserNameRetrieved;
protected TextView mUserAgeRetrieved;
protected TextView mUserHeadlineRetrieved;
String userGender = ParseUser.getCurrentUser().getString("Gender");
String activityName = ParseUser.getCurrentUser().getString("ActivityName");
Number maxDistance = ParseUser.getCurrentUser().getNumber(
"Maximum_Distance");
String userLookingGender = ParseUser.getCurrentUser().getString(
"Looking_Gender");
Number minimumAge = ParseUser.getCurrentUser().getNumber("Minimum_Age");
Number maximumAge = ParseUser.getCurrentUser().getNumber("Maximum_Age");
Number userage = ParseUser.getCurrentUser().getNumber("Age");
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.matchoption);
final Button idrinks = (Button) this.findViewById(R.id.btnQuickChat);
idrinks.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
openConversation();
}
private void openConversation() {
// TODO Auto-generated method stub
ParseQuery<ParseUser> query = ParseUser.getQuery();
query.whereNotEqualTo("objectId", ParseUser.getCurrentUser()
.getObjectId());
// users with Gender = currentUser.Looking_Gender
query.whereEqualTo("Gender", userLookingGender);
// users with Looking_Gender = currentUser.Gender
query.whereEqualTo("Looking_Gender", userGender);
query.setLimit(1);
query.whereEqualTo("ActivityName", activityName);
query.findInBackground(new FindCallback<ParseUser>() {
public void done(List<ParseUser> user, ParseException e) {
if (e == null) {
Intent intent = new Intent(
getApplicationContext(), MessagingActivity.class);
intent.putExtra("Name", user.get(0).getObjectId());
startActivity(intent);
} else {
Toast.makeText(getApplicationContext(),
"Error finding that user", Toast.LENGTH_SHORT)
.show();
}
}
});
}
});
}
以下是消息传递活动的活动代码
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
}
}
我已验证 APP_KEY、APP_SECRET 和 ENVIRONMENT 与 Sinch 上记录的内容相匹配。我在模拟器和物理设备上都试过了。
提前致谢
