Gitter.im Java SDK
Gitter.im Java SDK that facilitates communication with Gitter API, Gitter Streaming API, Gitter Faye API.
It provides three approaches to work with API:
- RxJava approach;
- Async (callback) approach.
- Sync approach.

Authentication Please read Authentication article on Gitter Developer before.
How to authenticate user with SDK
- Setup GitterDeveloperCredentials with info from here:
GitterDeveloperCredentials.init(new SimpleGitterCredentialsProvider(your_oauth_key, your_oauth_secret, your_redirect_url));
- Get Gitter request access URL:
String gitterAccessUrl = GitterOauthUtils.buildOauthUrl();
- Open this url in something like embedded browser and listen for redirects.
- When user grants access gitter redirects back with url like:
http://some.redirect.url?code=deadbeef
extract code
parameter value.
- Exchange code for access token:
- Rx:
RxGitterAuthenticationClient authenticationClient = new RxGitterAuthenticationClient.Builder().build();
authenticationClient.getAccessToken(code).subscribe(new Action1<AccessTokenResponse>() {
@Override
public void call(AccessTokenResponse accessTokenResponse) {
System.out.println("Access token = " + accessTokenResponse.accessToken);
}
}
);
- Async:
AsyncGitterAuthenticationClient authenticationClient = new AsyncGitterAuthenticationClient.Builder()
.build();
authenticationClient.getAccessToken(code, new Callback<AccessTokenResponse>() {
@Override
public void success(AccessTokenResponse tokenResponse, Response response) {
System.out.println("Access token = " + accessTokenResponse.accessToken);
}
@Override
public void failure(RetrofitError error) {
}
}
);
- Sync:
SyncGitterAuthenticationClient authenticationClient = new SyncGitterAuthenticationClient.Builder()
.build();
AccessTokenResponse accessTokenResponse = authenticationClient.getAccessToken(code);
System.out.println("Access token = " + accessTokenResponse.accessToken);
- Save and use this
accessToken
to make requests to the REST API.
How to get data from Gitter REST API
- Create
GitterApiClient
with help ofGitterApiClient.Builder
:
- Rx:
RxGitterApiClient client = new RxGitterApiClient.Builder()
.withAccountToken("user_access_token")
.build();
- Async:
AsyncGitterApiClient client = new AsyncGitterApiClient.Builder()
.withAccountToken("user_access_token")
.build();
- Sync:
SyncGitterApiClient client = new SyncGitterApiClient.Builder()
.withAccountToken("user_access_token")
.build();
also you can provide some Retrofit config for requests (same for Rx and Async):
RxGitterApiClient client = new RxGitterApiClient.Builder()
.withAccountToken("user_access_token")
.withClient(new OkClient())
.withExecutors(httpExecutor, callbackExecutor)
.withLogLevel(RestAdapter.LogLevel.BASIC)
.build();
- Execute any request that you need:
- Rx:
client.getCurrentUser().subscribe(new Action1<UserResponse>() {
@Override
public void call(UserResponse user) {
System.out.println("user.displayName = " + user.displayName);
}
}
);
- Async:
client.getCurrentUser(new Callback<UserResponse>() {
@Override
public void success(UserResponse userResponse, Response response) {
System.out.println("userResponse.displayName = " + userResponse.displayName);
}
@Override
public void failure(RetrofitError error) {
System.err.println("error = " + error);
}
}
);
- Sync:
UserResponse userResponse = client.getCurrentUser();
System.out.println("userResponse.displayName = " + userResponse.displayName);
or
- Rx:
ChatMessagesRequestParams params = new ChatMessagesRequestParamsBuilder().limit(20).build();
String roomId = "room_id"; client.getRoomMessages(roomId, params).subscribe(new Action1<List<MessageResponse>>() {
@Override
public void call(List<MessageResponse> messages) {
System.out.println("Received " + messages.size() + " messages");
}
}
);
- Async:
ChatMessagesRequestParams params = new ChatMessagesRequestParamsBuilder().limit(20).build();
String roomId = "room_id"; client.getRoomMessages(roomId, params, new Callback<List<MessageResponse>>() {
@Override
public void success(List<MessageResponse> messages, Response response) {
System.out.println("Received " + messages.size() + " messages");
}
@Override
public void failure(RetrofitError error) {
}
}
);
- Sync:
ChatMessagesRequestParams params = new ChatMessagesRequestParamsBuilder().limit(20).build();
String roomId = "room_id"; List<MessageResponse> messages = client.getRoomMessages(roomId, params);
System.out.println("Received " + messages.size() + " messages");
or
- Rx:
client.getUserChannels("user_id").subscribe(new Action1<List<RoomResponse>>() {
@Override
public void call(List<RoomResponse> rooms) {
System.out.println("Received " + rooms.size() + " rooms");
}
}
);
- Async:
client.getUserChannels("user_id", new Callback<List<RoomResponse>>() {
@Override
public void success(List<RoomResponse> rooms, Response response) {
System.out.println("Received " + rooms.size() + " rooms");
}
@Override
public void failure(RetrofitError error) {
}
}
);
- Sync:
List<RoomResponse> rooms = client.getUserChannels("user_id");
System.out.println("Received " + rooms.size() + " rooms");
### How to get streaming data from Gitter Streaming API
❗? Please don't set any log level for RxGitterStreamingApiClient as it blocks the stream.
java.net.SocketTimeoutException: Read timed out
try to encrease ReadTimeout
in your retrofit.client.Client
and spicify this client for GutterApiClient
( withClient()
).
RxGitterStreamingApiClient client = new RxGitterStreamingApiClient.Builder()
.withAccountToken("user_access_token")
.build();
String roomId = "room_id"; client.getRoomMessagesStream(roomId).subscribe(new Action1<MessageResponse>() {
@Override public void call(MessageResponse messageResponse) {
System.out.println("messageResponse = " + messageResponse);
}
}
);
or
RxGitterStreamingApiClient client = new RxGitterStreamingApiClient.Builder()
.withAccountToken("user_access_token")
.build();
String roomId = "room_id"; client.getRoomEventsStream(roomId).subscribe(new Action1<RoomEvent>() {
@Override public void call(RoomEvent event) {
System.out.println(event.sent);
System.out.println(event.meta);
}
}
);
###How to work with Gitter Faye API
1 Setup AsyncGitterFayeClient
:
AsyncGitterFayeClient client = new AsyncGitterFayeClientBuilder()
.withAccountToken("account_token")
.withOnDisconnected(new DisconnectionListener() {
@Override
public void onDisconnected() {
// Client has disconnected. You can reconnect it here.
}
}
)
.withOkHttpClient(new OkHttpClient())
.build();
2 Connect it to the server:
client.connect(new ConnectionListener() {
@Override
public void onConnected() {
// Client is ready. Subscribe to channels you are intereseted in.
}
}
);
3 Subscribe to desighed channel:
client.subscribe(new RoomMessagesChannel("room_id") {
@Override
public void onMessage(String channel, MessageEvent message) {
// Yeah, you've got message here.
}
}
);
or
client.subscribe(new RoomUserPresenceChannel("room_id") {
@Override
public void onMessage(String channel, UserPresenceEvent message) {
// User is active or not.
}
}
);
or
client.subscribe(new RoomUsersChannel("room_id") {
@Override
public void onMessage(String channel, UserEvent message) {
// User left ot joined the room.
}
}
);
or define your custom channel:
client.subscribe("channel_name",new ChannelListener(){
@Override public void onMessage(String channel,JsonObject message){
//
Handle message here.
}
@Override public void onFailed(String channel,Exception ex){
}
@Override public void onSubscribed(String channel, List<MessageResponse> messagesSnapshot){
}
@Override public void onUnSubscribed(String channel){
}
}
);
You can unsubscribe from channel:
client.unSubscribe("channel_name");
or
RoomMessagesChannel channel = new RoomMessagesChannel("room_id") {
@Override
public void onMessage(String channel, MessageEvent message) {
}
}
; client.subscribe(channel);
client.unSubscribe(channel);
Finally when your are finished with client, you need to call:
client.disconnect();
Thats all =).
