  1. Register a new account following this link. Type in your email and password to sign in. You can also sign in with your Google or Github accounts.
  2. Create the app clicking New app button.
  3. Configure the app. Type in the information about your organization into corresponding fields and click Add button.
  4. Go to Dashboard => YOUR_APP => Overview section and copy your Application ID, Authorization Key, Authorization Secret, and Account Key .

Requirements

The minimum requirements for QuickBlox Android SDK are:

  • Android 5.0 (API 21)
  • Android Studio
  • Gradle 4.6
  • Gradle plugin 2.5.1

Install QuickBlox SDK into your app

To connect QuickBlox SDK to your app, import QuickBlox SDK dependencies via build.gradle file.

Include reference to SDK repository in your project-level build.gradle file at the root directory. Specify the URL of QuickBlox repository where the files are stored. Following this URL gradle finds SDK artifacts.

allprojects {
    repositories {
        google()
        jcenter()
        maven {
            url "https://github.com/QuickBlox/quickblox-android-sdk-releases/raw/master/"
        }
    }
}

def qbSdkVersion = '3.9.2'

When the artifacts are found in QuickBlox repository, they get imported to particular SDK modules in build.gradle project file. Add the following code lines to app-level build.gradle file.

dependencies {
    implementation "com.quickblox:quickblox-android-sdk-messages:3.9.2"
    implementation "com.quickblox:quickblox-android-sdk-chat:3.9.2"
    implementation "com.quickblox:quickblox-android-sdk-content:3.9.2"
    implementation "com.quickblox:quickblox-android-sdk-videochat-webrtc:3.9.2"
    implementation "com.quickblox:quickblox-android-sdk-conference:3.9.2"
    implementation "com.quickblox:quickblox-android-sdk-customobjects:3.9.2"
}

Send your first message

Initialize QuickBlox SDK

Initialize the framework with your application credentials. Pass APPLICATION_ID, AUTH_KEY, AUTH_SECRET, and ACCOUNT_KEY to the init() method.

🚧

You must initialize SDK before calling any methods through the SDK, except for the init() method. If you attempt to call a method without connecting, the error is returned.

static final String APPLICATION_ID = "67895";
static final String AUTH_KEY = "lkjdueksu7392kj";
static final String AUTH_SECRET = "BTFsj7Rtt27DAmT";
static final String ACCOUNT_KEY = "9yvTe17TmjNPqDoYtfqp";
//
QBSettings.getInstance().init(getApplicationContext(), APPLICATION_ID, AUTH_KEY, AUTH_SECRET);
QBSettings.getInstance().setAccountKey(ACCOUNT_KEY);
private const val APPLICATION_ID = "67895"
private const val AUTH_KEY = "lkjdueksu7392kj"
private const val AUTH_SECRET = "BTFsj7Rtt27DAmT"
private const val ACCOUNT_KEY = "9yvTe17TmjNPqDoYtfqp"
//
QBSettings.getInstance().init(applicationContext, APPLICATION_ID, AUTH_KEY, AUTH_SECRET)
QBSettings.getInstance().accountKey = ACCOUNT_KEY

Authorize user

In order to use the abilities of QuickBlox SDK, you need to authorize your app on the server, log in to your account, and create a session. To get it all done call the signIn() method and pass the instance of QBUser with defined login and password to it using the code snippet below.

📘

To login with a user, you need login (or email) and password only. Other fields are optional (full name, phone, external ID, etc).

final QBUser user = new QBUser();
user.setLogin("johnsmith");
user.setPassword("johnPassword");

QBUsers.signIn(user).performAsync(new QBEntityCallback<QBUser>() {
    @Override
    public void onSuccess(QBUser user, Bundle bundle) {
        
    }

    @Override
    public void onError(QBResponseException exception) {
        
    }
});
val user = QBUser()
user.login = "johnsmith"
user.password = "johnPassword"

QBUsers.signIn(user).performAsync(object : QBEntityCallback<QBUser> {
    override fun onSuccess(user: QBUser?, bundle: Bundle?) {
        
    }

    override fun onError(exception: QBResponseException?) {
        
    }
})

Connect to Chat

Having authorized with a user, you can proceed with connecting to the Chat server to start using Chat module functionality. Call the login() method to connect to the Chat server.

QBChatService.getInstance().login(user, new QBEntityCallback() {
    @Override
    public void onSuccess(Void aVoid, Bundle bundle) {
 
    }

    @Override
    public void onError(QBResponseException exception) {

    }
});
QBChatService.getInstance().login(user, object : QBEntityCallback<Void> {
    override fun onSuccess(aVoid: Void?, bundle: Bundle?) {

    }

    override fun onError(exception: QBResponseException?) {

    }
})

Create dialog

QuickBlox provides three types of dialogs: 1-1 dialog, group dialog, and public dialog. Learn more about dialogs here.

Specify occupantIdsList within ArrayList. Create a QBChatDialog instance and specify QBdialogueType via dialog.setType() method. Specify occupantsIds from the ArrayList to add participants of the dialog being created. Once the instance is created, pass it by calling the createChatDialog() method.

ArrayList<Integer> occupantIdsList = new ArrayList<Integer>();
int occupantId = 123;
occupantIdsList.add(occupantId);
 
QBChatDialog dialog = new QBChatDialog();
dialog.setType(QBDialogType.PRIVATE);
dialog.setOccupantsIds(occupantIdsList);
 
// or just use DialogUtils
//QBChatDialog dialog = DialogUtils.buildPrivateDialog(recipientId);
 
QBRestChatService.createChatDialog(dialog).performAsync(new QBEntityCallback<QBChatDialog>() {
    @Override
    public void onSuccess(QBChatDialog result, Bundle bundle) {
 
    }
 
    @Override
    public void onError(QBResponseException exception) {
 
    }
});
val occupantIdsList = ArrayList<Int>()
val occupantId = 123
occupantIdsList.add(occupantId)

val dialog = QBChatDialog()
dialog.type = QBDialogType.PRIVATE
dialog.setOccupantsIds(occupantIdsList)

// or just use DialogUtils
//QBChatDialog dialog = DialogUtils.buildPrivateDialog(recipientId);

QBRestChatService.createChatDialog(dialog).performAsync(object : QBEntityCallback<QBChatDialog> {
    override fun onSuccess(result: QBChatDialog?, bundle: Bundle?) {

    }

    override fun onError(exception: QBResponseException?) {

    }
})

Subscribe to receive messages

Through QBDialogMessageListener you can monitor whether an incoming message or error is received from QuickBlox server. Use QBIncomingMessagesManager to listen to all incoming messages and related errors.

QBChatService chatService = QBChatService.getInstance();
QBIncomingMessagesManager incomingMessagesManager = chatService.getIncomingMessagesManager();

incomingMessagesManager.addDialogMessageListener(new QBChatDialogMessageListener() {
    @Override
    public void processMessage(String dialogId, QBChatMessage chatMessage, Integer senderId) {

    }

    @Override
    public void processError(String dialogId, QBChatException exception, QBChatMessage chatMessage, Integer senderId) {

    }
});
val chatService = QBChatService.getInstance()
val incomingMessagesManager = chatService.incomingMessagesManager

incomingMessagesManager.addDialogMessageListener(object : QBChatDialogMessageListener {
    override fun processMessage(dialogID: String?, qbChatMessage: QBChatMessage?, senderID: Int?) {

    }

    override fun processError(dialogID: String?, e: QBChatException?, qbChatMessage: QBChatMessage?, senderID: Int?) {

    }
})

Join dialog and send message

Before sending a message you should join the dialog you created by using:

DiscussionHistory history = new DiscussionHistory();
history.setMaxStanzas(0);
dialog.join(history, new QBEntityCallback() {
    @Override
    public void onSuccess(Object object, Bundle bundle) {
      
    }

    @Override
    public void onError(QBResponseException exception) {
    
    }
});
val history = DiscussionHistory()
history.maxStanzas = 0
dialog.join(history, object : QBEntityCallback<Void> {
    override fun onSuccess(aVoid: Void?, bundle: Bundle?) {
    
    }

    override fun onError(exception: QBResponseException?) {
    
    }
})

To send a message, create QBChatMessage instance and specify a text message via chatMessage.setBody parameter. Then, call the sendMessage() method and pass QBChatMessage instance within it.

QBChatMessage chatMessage = new QBChatMessage();
chatMessage.setBody("Hello QuickBlox!");

dialog.sendMessage(chatMessage, new QBEntityCallback<Void>() {
    @Override
    public void onSuccess(Void aVoid, Bundle bundle) {

    }

    @Override
    public void onError(QBResponseException exception) {

    }
});
val chatMessage = QBChatMessage()
chatMessage.body = "Hello QuickBlox!"

dialog.sendMessage(chatMessage, object : QBEntityCallback<Void> {
    override fun onSuccess(aVoid: Void?, bundle: Bundle?) {

    }

    override fun onError(exception: QBResponseException?) {

    }
})
