36 Oracle Android

Using the Oracle Android SDK for Oracle Digital Assistant, you can integrate your digital assistant with Android apps. The SDK connects to the Oracle Chat Server, the intermediary between the Oracle Android channel configured in Oracle Digital Assistant and the client. The chat server then passes messages to the skill for processing and delivers the skill's response to the client.

Note:

The Oracle Android Channel doesn't store messages when the client has disconnected from the server. It only delivers messages to connected clients. The SDK does not support multi-device login; it supports only one client per user.

This SDK works with instances of Oracle Digital Assistant that were provisioned on Oracle Cloud Infrastructure (sometimes referred to as the Generation 2 cloud infrastructure). If your instance is provisioned on the Oracle Cloud Platform (as all version 19.4.1 instances are), you can use Legacy Android SDK.

What Do You Need?

  • An Oracle Android Channel. Creating the channel generates the Channel ID and the Secret Key that you need to initialize the chat view.
  • The URL of the Oracle Chat Server.
  • The Android SDK. Download it from the ODA and OMC download page and extract it to your local system. This ZIP includes a user guide that describes the SDK's functions a sample app that demonstrates many of its features, and JavaDoc of all the classes.
  • API Level 29 (Android 10. "Q"). API Level 21(Lollipop) is the lowest version that can support the Digital Assistant Client SDK for Android. If your app needs to support even earlier versions, keep in mind that we haven't tested these and therefore can't guarantee their compatibility.

    Note:

    Speech recognition has been tested for API level 23 (Marshmallow) and higher. It may not work on API levels below 23

Create the Oracle Android Channel

You can configure the channel to connect to the Oracle Chat Server in two modes: unauthenticated mode and authenticated mode (to protect access to the channel).
  • Unauthenticated mode – Use the unauthenticated mode when the client can't generate signed JWT tokens, when no authentication mechanism is in place, or when the client app is already secured and visible to authenticated users.
  • Authenticated mode – Authentication is enforced using JSON Web Tokens (JWT). The customer's backend server generates the JWT token, which is then passed to the Oracle Andriod SDK. This token is used for each request to an ODA speech, text, or attachment server.

    Note:

    To protect access to the channel, the token must always be generated by a remote server. It must never be generated within by the client app.
    When the app needs to connect to an ODA server, it first requests the token from the backend server and then adds it to the Authorization header. The ODA server validates the token, evaluates the claims, and then either opens the socket or rejects the connection.
The JWT Token has the following claims: channelId and userId, and the claim names iat (issued at time), and exp (expiration time). iat signifies the time at which the token was issued. This must be a number that represents the seconds that have elapsed since the UNIX epoch. exp must be a number representing the seconds that have elapsed since the UNIX epoch. We recommend setting the expiration time to at least 30 minutes after the issued at time (iat). The token header looks something like this:
{

 "alg": "HS256",

 "typ": "JWT"

}
An example token body looks something like this:
{

  "iat": 1569828182,

  "exp": 1569831782,

  "channelId": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",

  "userId": "John"

}

Note:

The token illustrated by this example is not signed. The actual tokens are signed by channel's Secret Key.

Configure the Oracle Android Channel

To configure the Oracle Android channel:
  1. Choose Development, then Channels from the menu.
  2. Choose Users.
  3. Click Add Channel and then Oracle Android as the channel type.
  4. Complete the dialog:
    • Enter the channel name.
    • For authenticated connections:
      • Switch on the Client Authentication Enabled toggle to determine whether the SDK is connecting to a client authentication-enabled channel.
      • In the Max. Token Expiration (Minutes) field, set the maximum amount of time for the JWT token.
    • For unauthenticated connections:
      • Switch off Client Authentication Enable toggle.
    • Set the Session expiration time.
    • Click Create. Oracle Digital Assistant will generate the Channel ID and the Secret Key that you need to initialize the SDK. Keep these close at hand.
  5. Route the channel to your skill or digital assistant.
  6. Switch Channel Enabled to On.

Add the Oracle Android Client SDK to the Project

To add the SDK:
  1. Download the ODA Client SDK for Android and extract it to your local system.
  2. In Android Studio, select your project's App directory and then click File > New > New Module.
  3. Choose Import JAR/.AAR Package and then click Next.
  4. Navigate to, and select, com.oracle.bots.client.sdk.android.core-20.8.1.aar. Click Finish.
  5. Repeat these steps to import com.oracle.bots.client.sdk.android.ui-20.8.1.aar.

    Note:

    You don't need to import this package if you're using the SDK in headless mode.
  6. Ensure that these libraries are listed at the top of project's settings.gradle file. For example:
    include ':app', ':com.oracle.bots.client.sdk.android.core-20.8.1', ':com.oracle.bots.client.sdk.android.ui-20.8.1'
rootProject.name = 'ODASDKSample'
  7. Add the following to the dependencies in the build.gradle (Module: app) file. These dependencies include:
    • The SDK library dependency
    • Core and UI dependencies which are used by the SDK library for the smooth functioning of library features.
      // SDK

Initialize the Oracle Android Client SDK in Your App

Initialize Oracle Android Client SDK in your Application class. Initialize the SDK describes the different methods that you can use to initialize the SDK. The JavaDoc that's included with the SDK describes all of the available classes.

If you're connecting to a channel with client authentication disabled, pass false as the second parameter to the BotsConfiguration.BotsConfigurationBuilder() constructor function.
import android.app.Application;
import oracle.cloud.bots.mobile.core.Bots;
import oracle.cloud.bots.mobile.core.BotsCallback;
import oracle.cloud.bots.mobile.core.BotsConfiguration;
import oracle.cloud.bots.mobile.core.BotsSDKException;

public class YourApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        try {
                BotsConfiguration botsConfiguration = new BotsConfiguration.BotsConfigurationBuilder(<SERVER_URI>, false, getApplicationContext()) // Configuration to initialize the SDK
                    .channelId(<CHANNEL_ID>)
                    .userId(<USER_ID>)
                    .build();

                Bots.init(this, botsConfiguration, new BotsCallback() {  // Initialize the SDK
                    @Override
                    public void onSuccess(Response paramResponse) {
                        // Handle init success
                    }
                    @Override
                    public void onFailure(Response paramResponse) {
                        // Handle init failure
                    }
                });
        } catch (BotsSDKException e) {
           // Handle Exceptions thrown by SDK
        }
    }
}

If you are connecting to a channel with client authentication enabled, you need to make some minor modifications: along with passing true as the second parameter to the BotsConfiguration.BotsConfigurationBuilder() constructor function, you also need to set the authTokenProvider property with the instance of type AuthenticationTokenProvider that can be used to generate and pass the JWT token.

The class should implement the AuthenticationTokenProvider interface, which then overrides the getAuthToken() function to generate and return a JWT token. The function will be used by the SDK to generate a new token whenever it needs to establish a new connection and existing token is expired. The code would look something like this:
import android.app.Application;
import oracle.cloud.bots.mobile.core.AuthenticationTokenProvider;
import oracle.cloud.bots.mobile.core.Bots;
import oracle.cloud.bots.mobile.core.BotsCallback;
import oracle.cloud.bots.mobile.core.BotsConfiguration;
import oracle.cloud.bots.mobile.core.BotsSDKException;

public class YourApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        try {
                BotsConfiguration botsConfiguration = new BotsConfiguration.BotsConfigurationBuilder(<SERVER_URI>, true, getApplicationContext()) //  Configuration to initialize the SDK
                    .authTokenProvider(new AuthTokenProvider())
                    .build();

                Bots.init(this, botsConfiguration, new BotsCallback() {  // Initialize the SDK
                    @Override
                    public void onSuccess(Response paramResponse) {
                        // Handle init success
                    }
                    @Override
                    public void onFailure(Response paramResponse) {
                        // Handle init failure
                    }
                });
        } catch (BotsSDKException e) {
           // Handle Exceptions thrown by SDK
        }
    }

    private class AuthTokenProvider implements AuthenticationTokenProvider {
        @Override
        public String getAuthToken() {
            // Generate a new JWT Token and return
        }
    }
}

Custom Colors

You can modify the chat view's colors to give it a custom look. To configure these colors, define name attributes for the <color> elements in the res/values/colors.xml file (located in the project's app resources) using the the following keys. The following snippet demonstrates a modifications of the color that's used for the background of the skill's message (odaas_primary) and the text color used in the skill's (odaas_on_primary) message while maintaining the default colors for other resources.
<resources>
    <color name="odaas_primary">#6699FF</color>
    <color name="odaas_on_primary">#000000</color>
</resources>

Note:

Version 20.8.1 of the SDK resets the colors for prior versions. For example, if the background color of the action buttons in the existing implementation is #418980, then this will be changed to the default color of odaas_action_background (introduced in 20.8.1), which is #FFFFFF. For implementations created using versions prior to 20.8.1, you can set custom colors by updating the res/values/colors.xml file in your application. For example:

Localization
To localize these strings, define the name attributes for the <string> elements in the app resource's res/values-<your-language-code>/strings.xml file with the keys. For example, to localize the title of the chat view in English, define the following in a file called res/value-en/strings.xml:
<resources>
    <string name="odaas_bot_chat_title">Support</string>
</resources>
To localize the title in French, you'd add the following to a file called res/value-fr/strings.xml file:
<resources>
    <string name="odaas_bot_chat_title">Soutien</string>
</resources>
The values for res/value/strings.xml are used by default for the keys that are not found in res/values-<your-language-code>/strings.xml. For these two examples, the default values would be used for the resources that are not defined in either the res/value-fr/strings.xml or res/value-en/strings.xml files.

Custom Icons

Configure drawables by adding the required images or vector assets to the app resource's res/drawable folder that have the following names.
Name Description
ic_odaas_agent_avatar The avatar icon for the messages from the live agent. This icon displays in notifications only when the showBotAvatar feature flag is set to true.
ic_odaas_bot_avatar The avatar icon for the skill's messages. This icon displays on notifications only when the showBotAvatar feature flag is set to true.
ic_odaas_notification_app_icon The app icon displayed in the status bar and on notifications received from SDK library.

    <NOTIFICATION_CHANNEL_NAME>, <NOTIFICATION_CHANNEL_DESCRIPTION>, <NOTIFICATION_TITLE>);

Features

Delegation
The delegation feature lets you set a delegate to receive callbacks before certain events in the conversation. To set a delegate, a class must implement the interface MessageModifierDelegate and pass its instance to the messageModifierDelegate property.
private MessageDelegate implements MessageModifierDelegate {
    @Override
    public Message beforeSend(Message message) {
        // Handle before send delegate here
    }

    @Override
    public Message beforeDisplay(Message message) {
        if (message != null && message.getPayload() != null && message.getPayload().getType() == MessagePayload.MessageType.CARD) {
            ((CardMessagePayload)message.getPayload()).setLayout(CardLayout.VERTICAL);
        }
        return message;
    }

    @Override
    public Message beforeNotification(Message message) {
        // Handle before notification delegate here
    }
}
public Message beforeDisplay(Message message)

The public Message beforeDisplay(Message message) delegate allows a skill's message to be modified before it is displayed in the conversation. The modified message that's returned by the delegate displays in the conversation. If the method returns null, then the message is not displayed.

public Message beforeDisplay(Message message)

The public Message beforeDisplay(Message message) delegate allows a user message to be modified before it is sent to the chat server. The message returned by the delegate is sent to the skill. If it returns null, then the message is not sent.

public Message beforeNotification(Message message)

The public Message beforeNotification(Message message) delegate allows a skill's message to be modified before a notification is triggered. If it returns null, then the notification is not triggered.

Headless SDK

The SDK can be used without its UI. To use it in this mode, import only the com.oracle.bots.client.sdk.android.core-20.8.1.aar package into the project as described in Add the Oracle Android Client SDK to the Project.

The SDK maintains the connection to server and provides APIs to send messages, receive messages, and get updates for the network status and for other services. You can use the APIs to interact with the SDK and update the UI.

You can send a message using any of the send*() APIs available in Bots class. For example, public static void sendMessage(String text) sends text message to skill or digital assistant.

public static void sendMessage(String text)
Sends a text message to the skill. Its text parameter is the text message.
Bots.sendMessage("I want to order a Pizza");
EventListener
To listen for the connection status change, the message sent to the skill and received from the skill, and the attachment upload status events, a class should implement the EventListener interface, which then implements the functionality for:
  • void onStatusChange(ConnectionStatus connectionStatus) – This method is called when the WebSocket connection status changes. Its connectionStatus parameter is the current status of the connection. Refer to the Javadocs included in the SDK (available from the ODA and OMC download page ) for more details about the ConnectionStatus enum.
  • void onMessageReceived(Message message) – This method is called when a new message is received from the skill. Its message parameter is the message received from the skill. Refer to the Javadocs included in the SDK (available from the ODA and OMC download page ) for more details about the Message class.
  • void onMessageSent(Message message) - This method is called when a message is sent to the skill. Its message parameter is the message sent to the skill. Refer to the Javadocs included in the SDK (available from the ODA and OMC download page ) for more details about the Message class.
  • void onAttachmentComplete() – This method is called when an attachment upload has completed. 
public class BotsEventListener implements EventListener {
    @Override
    public void onStatusChange(ConnectionStatus connectionStatus) {
        // Handle the connection status change
    }
 
    @Override
    public void onMessageReceived(Message message) {
        // Handle the messages received from skill/DA
    }
 
 
    @Override
    public void onMessageSent(Message message) {
        // Handle the message sent to skill or Digital Assistant
    }
 
    @Override
    public void onAttachmentComplete(String utterance) {
        // Handle the post attachment upload actions
        // Close the attachment upload progress popup if any etc.
    }
}
The instance of type EventListener should then be passed to setEventListener(EventListener eventListener).
public static void setEventListener(EventListener eventListener)
Sets the listener to receive the response returned from the skill to get updates on connection status change and to receive an update when the attachment upload is complete. Its eventListener parameter is an instance of type EventListener to receive updates.
Bots.setEventListener(new BotsEventListener());
Share Menu Options
By default, the share menu displays options for the following file types:
  • visual media files (images and videos)
  • audio files
  • general files like documents, PDFs, and spreadsheets
  • location
The shareMenuItems(HashSet<ShareMenuItem>) setting allows you to restrict the items that display in the share menu. The configuration accepts a HashSet of ShareMenuItem enum values which are mapped to the share menu items: ShareMenuItem.CAMERA for showing camera menu item (if supported by the device), ShareMenuItem.VISUAL for the share image/video item, ShareMenuItem.AUDIO for the share audio item, and ShareMenuItem.FILE for the share file item. Only the menu items for the values passed in the HashSet display in the share popup. Passing an empty or a null value results in all of the menu items displaying together in the share popup.

Note:

This configuration only applies when enableAttachment is set to true.
Speech Recognition

Setting the enableSpeechRecognition feature flag to true enables the microphone button to display in place of the send button whenever the user input field is empty.

Setting this property to true also supports the functionality enabled by the enableSpeechRecognitionAutoSend property, which when also set to true, enables the user's speech response to be sent to the chat server automatically while displaying the response as a sent message in the chat window. You can allow users to first edit (or delete) their dictated messages before they send them manually by setting enableSpeechRecognitionAutoSend to false.

Speech recognition is utilized through the following methods:
public static void startRecording(IBotsSpeechListener listener)

Starts recording the user's voice message. The listener parameter is an instance of IBotsSpeechListener to receive the response returned from the server.

public static void stopRecording()

Stops recording the user's voice message.

public static boolean isRecording()

Checks whether the voice recording has started or not. Returns true if the recording has started. Otherwise, it returns false.

IBotsSpeechListener
A class should implement the interface IBotsSpeechListener which then implements the functionality for the following methods:
void onError(String error)

This method is called when errors occur while establishing the connection to the server, or when there is either no input given or when too much input is given. Its error parameter is the error message.

void onSuccess(String utterance)

This method is called when a final result is received from the server. Its utterance parameter is the final utterance received from the server.

Note:

This method is deprecated in Release 20.8.1.

void onSuccess(BotsSpeechResult botsSpeechResult)

This method is called when a final result is received from the server. Its parameter, botsSpeechResult, is the final response received from the server.

void onPartialResult(String utterance)

This method is called when a partial result is received from the server. Its utterance parameter is the partial utterance received from the server.

void onClose(int code, String message)

This method is called when the connection to server closes.

Parameters:
  • code – The status code
  • message – The reason for closing the connection
void onOpen()

The method called when the connection to server opens.

onActiveSpeechUpdate(byte[] speechData)
This method is called when there is an update in the user's voice message, which can then be used for updating the speech visualizer. It's parameter is speechData, the byte array of the recorded voice of user.
public class BotsSpeechListener implements IBotsSpeechListener {
    @Override
    public void onError(String error) {
            // Handle errors
    }
 
    @Override
    public void onSuccess(String utterance) {
        // This method was deprecated in release 20.8.1.
        // Handle final result
    }
 
 
    @Override
    public void onSuccess(BotsSpeechResult botsSpeechResult) {
        // Handle final result
    }  
 
    @Override
    public void onPartialResult(String utterance) {
        // Handle partial result
    }
 
    @Override
    public void onClose(int code, String message) {
        // Handle the close event of connection to server
    }
 
    @Override
    public void onOpen() {
        // Handle the open event of connection to server
    }
 
 
    @Override
    public void onActiveSpeechUpdate(byte[] speechData) {
        // Handle the speech update event
    }
}
 
 
Bots.startRecording(new BotsSpeechListener()); // Start voice recording
 
if (Bots.isRecording()) {
    Bots.stopRecording(); // Stop voice recording
}
Speech Synthesis
The SDK has been integrated with speech synthesis to read the skill's message aloud when a new message is received from skill:
  • Users can mute or unmute the skill's audio response using a button that's located in the header of the chat view. You enable this feature by setting the enableSpeechSynthesis feature flag to true.
  • You can set the preferred language that read the skill's messages aloud with the speechSynthesisVoicePreferences property. This parameter that sets the language and voice is a list of SpeechSynthesisSetting instances (described in the SDK's Javadoc that you download from the ODA and OMC download page). This property enables a fallback when the device doesn't support the preferred language or voice. If the device does not support the preferred voice, then the default voice for the preferred language is used instead. When neither the preferred voice or language are supported, then the default voice and language are used.
public static void initSpeechSynthesisService()
Initializes the speech synthesis service. This method should be called in the onCreate() method of an Activity to initialize the speech synthesis service. The initialization of speech synthesis service will be done when the SDK library initializes only if the enableSpeechSynthesis feature flag is set to true.
public class ConversationActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Bots.initSpeechSynthesisService();
    }
}
public static void startBotAudioResponse(String text)
Starts reading the skill's response aloud. Its text parameter is the text for the skill's message that's read aloud.
Bots.startBotAudioResponse("What kind of crust do you want?");
public static void stopBotAudioResponse()
Stops reading the skill's response aloud.
Bots.stopBotAudioResponse()
public static boolean isSpeaking()

Checks if the skill's response is currently being read aloud or not.

Returns true if the skill's response is currently being read aloud. Otherwise, it returns false.
if (Bots.isSpeaking()) {
    Bots.stopBotAudioResponse();
}
public static void shutdownBotAudioResponse()

Releases the resources used by the SDK.

This method is called in the onDestroy() method of ConversationActivity.
public class ConversationActivity extends AppCompatActivity {
    @Override
    protected void onDestroy() {
        super.onDestroy();
        Bots.shutdownBotAudioResponse();
    }
}
Voice Visualizer

When voice support is enabled (enableSpeechRecognition(true)), the footer of the chat widget displays a voice visualizer, a dynamic visualizer graph that indicates the frequency level of the voice input. The visualizer responds to the modulation of the user's voice by indicating whether the user is speaking too softly or too loudly. This visualizer is created using the stream of bytes that are recorded while the user is speaking, which is also exposed in the IBotsSpeechListener#onActiveSpeechUpdate(byte[]) method for use in headless mode.

The chat widget displays a voice visualizer when users click the voice icon. It's an indicator of whether the audio level is sufficiently high enough for the SDK to capture the user’s voice. The user’s message, as it is recognized as text, displays below the visualizer.

Note:

Voice mode is indicated when the keyboard icon appears.

When enableSpeechRecognitionAutoSend(true), the recognized text is automatically sent to the skill after the user has finished dictating the message. The mode then reverts to text input. When enableSpeechRecognitionAutoSend(false), the mode also reverts to text input, but in this case, users can modify the recognized text before sending the message to the skill.
