Android SDK Development Guide

Overview

JMessage provides developers with an easy-to-use and reliable IM development framework. Developers can integrate SDKs to quickly implement instant messaging capabilities. The SDK supports Android 2.3 or higher mobile phone systems.

To learn more about JMessage, please refer to the document: Product Introduction of JMessage

Message

The most important function of JMessage is instant messaging.

• Ensure timely delivery of messages;
• Single chat, group chat
• Message type: text, voice, picture, file, location, etc.
• Save offline messages when users are offline
• Based on JPush’s original large-capacity, stable long-term connection and concurrency capabilities of large-capacity message;

User

• The developer’s user is registered to JMessage based on username / password. SDK can initiate the registration of the user, or the server can initiate registration in batches.
• When the user logs in to the App, he also logs in to JMessage. After logging in, he can send chat messages to other usernames or receive messages from other usernames or group messages. Whether user A has permission to send a message to user B is controlled by the App logic itself.
• It is allowed to have users update user attributes such as avatars to JMessage.

Group

Multiple usernames can be added to a group to send group chat messages to the group.

• Create groups and quit groups;
• Add group members, remove group members;
• Public groups added in version 2.4.0

Friend

• From version 1.4.0, jmessage android sdk begins to provide interfaces for the hosting of user friend relationships and sending and receiving of related friend requests.

Chat Room

• From version 2.4.0, jmessage android sdk begins to provide chat room features, including basic information querying, join chat rooms, exit chat rooms. See details in chat room management.

String Specification

The field attributes and specifications in the JMessage are defined here for verification and normalization.

API List

Listed below are the main APIs provided by the JMessage SDK. For complete API and class information, visit: API Java docs

SDK Initialization

Before calling other interfaces of IM, you must first adjust this interface to initialize the SDK. It is recommended to call it in the application class. Message roaming is turned off by default.

JMessageClient.init(Context context)

Parameter Description

• Context context object in the application

SDK Initialization (Set Message History Roaming)

Since 2.1.0

Initialize SDK and specify whether to enable message history roaming.

After opening the message roaming, when a user logs in between multiple devices, sdk will automatically synchronize the history message of current user to the local device, and send a ConversationRefreshEvent event to notify the upper layer to refresh after the synchronization is completed. See the event handling section for specific event handling methods.

JMessageClient.init(Context context, boolean msgRoaming)

Parameter Description

• Context context object in the application.
• boolean msgRoaming Whether to enable message roaming, true - enable, false - turn off.

Registration and Login

Registration

JMessageClient.register(String username, String password, BasicCallback callback);
/**
 * 注册同时指定用户信息中的其他字段
 * @since 2.3.0
 */
JMessageClient.register(String userName, String password, RegisterOptionalUserInfo optionalUserInfo, BasicCallback callback);

Parameter Description

• String username
• String password
• RegisterOptionalUserInfo (optionalUserInfo: additional information of registered user)
• BasicCallback

Login

JMessageClient.login(String username, String password, BasicCallback callback);

Parameter Description

• String username
• String password
• BasicCallback callback

Logout

JMessageClient.logout();

Record of logging in

Since 2.5.0

Get login history of device when you log in

    /**
     * 用户登陆，并且在回调中获取用户账号所登陆过的设备信息{@link cn.jpush.im.android.api.model.DeviceInfo}<br/>
     * 每个端：移动端（Android 、iOS），PC端，Web端（JS、微信小程序）只保存最近一次设备登陆记录。
     *
     * @param userName 开发者注册的用户名，应该唯一。
     * @param password 用户登录密码，推荐将字符串加密。
     * @param callback 回调接口
     * @since 2.5.0
     */
    public static void login(String userName, String password, RequestCallback<List<DeviceInfo>> callback) {
        login(userName, password, (BasicCallback) callback);
    }

Monitor message sending result

After the message is sent, the interface will be called back to inform the upper layer.

message.setOnSendCompleteCallback(BasicCallback sendCompleteCallback)

Parameter Description

• BasicCallback sendCompleteCallback callback interface

Send message

Send a message through the server to the sending object and save it to the local session. Send by default configuration parameters

JMessageClient.sendMessage(Message message);

Parameter Description

• Message message - message object

Message sending with control parameters

Since 2.2.0
For the message sending operation, some optional parameter configurations are supported. See MessageSendingOptions for specific parameters.

JMessageClient.sendMessage(Message message, MessageSendingOptions options);

Parameter Description

• Message message - message object
• MessageSendingOptions - control options when sending messages

Example Code

Message message = mConversation.createSendMessage(new TextContent(“Hello jmessage.”));
message.setOnSendCompleteCallback(new BasicCallback() {
    @Override
    public void gotResult(int responseCode, String responseDesc) {
        if (responseCode == 0) {
            //消息发送成功
        } else {
            //消息发送失败
        }
    }
});
MessageSendingOptions options = new MessageSendingOptions();
options.setRetainOffline(false);
JMessageClient.sendMessage(message);//使用默认控制参数发送消息
//JMessageClient.sendMessage(message,options);//使用自定义的控制参数发送消息

Acquire local message record

Any message belongs to a certain session, so to obtain the local message record, you first need to obtain the conversation object conversation, and then obtain the message record in the session.

Get all messages in the session

    /**
     * 获取会话中所有消息，消息按照时间升序排列.<br/>
     *
     * @return 包含会话中所有消息的List
     */
    conversation.getAllMessage();

Get the message list by condition

    /**
     * 会话中消息按时间降序排列，从其中的offset位置，获取limit条数的消息.
     *
     * @param offset 获取消息的起始位置
     * @param limit  获取消息的条数
     * @return 符合查询条件的消息List, 如果查询失败则返回空的List。
     */
    conversation.getMessagesFromNewest(int offset, int limit)
    /**
     * 会话中消息按时间升序排列，从其中的offset位置，获取limit条数的消息.<br/>
     *
     * @param offset 获取消息的起始位置
     * @param limit  获取消息的条数
     * @return 符合查询条件的消息List, 如果查询失败则返回空的List。
     */
    conversation.getMessagesFromOldest(int offset, int limit);

Receive message

When sdk receives a message, it throws a MessageEvent or OfflineMessageEvent. Developers can get specific Message object through this event, and then perform UI refresh or other related logic. See the specific event processing method in Event Handling section

Changes of Received Message from Version 2.1.0

2.1.0版本开始，sdk将消息下发分为在线下发和离线下发两种类型。 先明确两个概念：Starting from the 2.1.0 release, sdk divides the message delivery into online delivery and offline delivery. First clear two concepts:

• Online messages: During the im user’s online period, all received messages are called online messages.
• Offline messages: Messages generated during the im user’s offline period (including logout or network disconnection) are temporarily stored on the Jiguang Server. When the user goes online again, sdk will pull this part of the message, which is called offline news.

With the distinction between these two concepts, sdk also handles these two messages differently:

Summary

After sdk is upgraded to version 2.1.0 (or later), the upper layer needs to make the following changes to the processing of message receiving:

• In addition to the MessageEvent, a new event type, OfflineMessageEvent, was added to receive offline message events.
• For developers who need message roaming, he needs add the reception of the ConversationRefreshEvent event. After the roaming message in the session is completed, sdk will trigger this event to notify the upper layer to refresh session.

Example Code：

    /**
      类似MessageEvent事件的接收，上层在需要的地方增加OfflineMessageEvent事件的接收
      即可实现离线消息的接收。
    **/
    public void onEvent(OfflineMessageEvent event) {
        //获取事件发生的会话对象
        Conversation conversation = event.getConversation();
        List<Message> newMessageList = event.getOfflineMessageList();//获取此次离线期间会话收到的新消息列表
        System.out.println(String.format(Locale.SIMPLIFIED_CHINESE, "收到%d条来自%s的离线消息。\n", newMessageList.size(), conversation.getTargetId()));
    }
    /**
      如果在JMessageClient.init时启用了消息漫游功能，则每当一个会话的漫游消息同步完成时
      sdk会发送此事件通知上层。
    **/
    public void onEvent(ConversationRefreshEvent event) {
        //获取事件发生的会话对象
        Conversation conversation = event.getConversation();
        //获取事件发生的原因，对于漫游完成触发的事件，此处的reason应该是
        //MSG_ROAMING_COMPLETE
        ConversationRefreshEvent.Reason reason = event.getReason();
        System.out.println(String.format(Locale.SIMPLIFIED_CHINESE, "收到ConversationRefreshEvent事件,待刷新的会话是%s.\n", conversation.getTargetId()));
        System.out.println("事件发生的原因 : " + reason);
    }

Retract Message

Retract a message in a conversation

Since 2.2.0
Initiated by the sender

conversation.retractMessage(Message message, BasicCallback callback)

Parameter Description

• Message message - Message entity of message that needs to be withdrawn
• BasicCallback callback - callback interface

Event notification to withdrawn party

Since 2.2.0
After the message sender initiates the withdrawal, the withdrawn party receives an event notification MessageRetractEvent. See the Event Handling section for how to handle specific events.

Note: Regardless of recalled party or withdrawn party, the message content is replaced with the PromtContent type after the message is withdrawn, and the content of the message becomes invisible.

Forward Message

Forward a message in a conversation

    /**
     * 转发消息,只有发送成功或收到的消息才可转发
     *
     * @param message  需要转发的消息对象
     * @param conv     目标会话

     * @since 2.6.0
     */
    JMessageClient.forwardMessage(Message message, Conversation conv, MessageSendingOptions options, final RequestCallback<Message> callback);

Message Read Receipt

Read receipt setting

The message sender can set whether to require the receiver to send a read receipt for a single message when sending the message. The default behavior is false Since 2.3.0

messageSendingOptions.setNeedReadReceipt(boolean needReadReceipt)

Parameter Description

• boolean needReadReceipt - Whether the receiver needs to send a read receipt. true - yes, false - no.

Get the number of people who have not sent a read receipt yet

When a message that requires the recipient to send a read receipt is successfully issued, the message sender can view the number of people who have not yet sent the read receipt. Since 2.3.0

  message.getUnreceiptCnt()

Interface return

• int - The number of people who have not yet sent read receipts.
Returns 0 when all recipients have read or this message does not require a read receipt

Get current read receipt details

After a message that requires the receiver to send a read receipt is successfully issued, the message sender can view the details of the current read receipt . The details include the UserInfo list of the user who has currently sent the read receipt and has not sent the read receipt.

Since 2.3.0

  message.getReceiptDetails(GetReceiptDetailsCallback callback)

Parameter Description

• GetReceiptDetailsCallback callback - result callback

The message receiver marks the message as read

For message receivers, a message can be marked as read. After successful marking, the read status of this message is recorded locally.

When this message is a message that requires read receipt, sdk will also send a notification event MessageReceiptStatusChangeEvent to the message sender to inform that the number of receivers who has sent read receipt has changed.

Note that this read state will only be saved locally, and the read state will be reset to false after the local data is cleared or the user changes the device to log in.

Since 2.3.0

  message.setHaveRead(BasicCallback callback)

Parameter Description

• BasicCallback callback - result callback

Get whether the message is read

For the message receiver, this interface can be used to obtain whether the message is read. By default, all read status of received messages is false. The read status of the message becomes true after successfully invoking the message.setHaveRead(BasicCallback callback) interface Note that this read state will only be saved locally, and the read state will be reset to false after the local data is cleared or the user changes the device to log in.

Since 2.3.0

  message.haveRead()

Interface return

• boolean: Read state of boolean messages. true - read, false - unread

Message Receipt Status Change Event

MessageReceiptStatusChangeEvent

For a message sent by a message sender that requires the receiver to send a read receipt, after the receiver successfully sends a read receipt via the message.setHaveRead(BasicCallback callback) interface, sdk throws the event notification message sender. Through this event, the sender can know the unreported number of which message in which session has changed. The specific processing method see the event handling section

Receipt-related example code:

//消息发送方：
//===========发送带已读回执的消息：
final Message message = mConversation.createSendMessage(new TextContent(“这是一条需要对方发送已读回执的消息.”));
message.setOnSendCompleteCallback(new BasicCallback() {
    @Override

Command Transparent Transmission

Since 2.3.0
Commands sent through the transparent transmission will not be saved offline, but will be pushed when the other user is online. After sdk receives the command, it will not be saved locally, and the notification bar will not be sent.

The overall response is fast.
Developers can use transparent transmission to extend auxiliary functions in some online scenarios, such as implementing input status prompts.

Event Handling

Register event receiving class

JMessageClient.registerEventReceiver(Object receiver);
JMessageClient.registerEventReceiver(Object receiver, int priority);

Parameter Description

• Object receiver - Object of message receiving class
• int priority - defines the priority of the event received. The default value is 0. The higher the priority, the earlier the event is received. (The priority is only valid for the receiver in the same thread mode)

Untie the event receiving class

JMessageClient.unRegisterEventReceiver(Object receiver);

Parameter Description

• Object receiver – object of message receiver. After the object is unbound, it will no longer receive any events.

Event reception

After registering the event receiving class, the following method needs to be implemented in the message receiving class to receive the corresponding message. Sdk will distinguish different thread modes according to the method name of the implementation method. The commonly used thread modes are onEvent (default thread mode) and onEventMainThread (main thread mode).

Different types of events can be received by defining different types of parameters. The specific event type is defined in the section “Event Types”

Default thread (child thread) mode

public void onEvent(EventEntity event){
  //do your own business
}

The method body will be called in the default thread (child thread) and can be used to handle time-consuming operations.

Parameter Definition

• EventEntity event - the event object. (Define that different types of parameters can receive different types of events. For specific usage, refer to “Example Code.”)

Main thread mode

public void onEventMainThread(EventEntity event){
  //do your own business
}

The method body will be called in the main thread and can be used to refresh the UI.

Parameter definition

• EventEntity event – the event object.

Group Members Banned

Since 2.4.0
The 2.4.0 version added a group member banned status setting. After the banning, the user can normally receive the message but cannot send a message to the banned group. After the ban is lifted, the message can be normally sent.

Group member banned state setting

Since 2.4.0

    /**
     * 群成员禁言状态设置,禁言后用户可正常接收消息，但无法向被禁言的群组中发送消息
     * 解禁后可正常发送消息,禁言状态设置成功后群内所有成员将会收到群禁言通知事件
     * sdk收到群禁言通知事件后会以类型为{@link cn.jpush.im.android.api.enums.ContentType#eventNotification}
     * 的消息事件方式上报
     *
     * @param username 待设置群成员的username
     * @param appKey 待设置群成员的appKey，传入空则默认使用本应用appKey
     * @param keepSilence //true 设置禁言， false 取消禁言
     * @param callback
     * @since 2.4.0
     */
    groupInfo.setGroupMemSilence(String username, String appKey, boolean keepSilence, BasicCallback callback);

Blacklist Management

You can add the other user to the “blacklist” list. After joining, we can still send a message to each other. However, it will return the specified error code when the other party sends a message to me, and the message will fail.

Add users to the blacklist

JMessageClient.addUsersToBlacklist(List<String> usernames, BasicCallback callback)

Parameter Description

• List usernames - usernames list of users added to the blacklist
• BasicCallback callback - callback interface

Remove users from the blacklist

JMessageClient.delUsersFromBlacklist(List<String> usernames, BasicCallback callback)

Parameter Description

• List usernames - Username list of users that have been removed from the blacklist
• BasicCallback callback - callback interface

Get a list of users who have been blacklisted by the current user

JMessageClient.getBlacklist(GetBlacklistCallback callback)

Parameter Description

• GetBlacklistCallback - get callback interface of blacklist

Callback

  public abstract void gotResult(int responseCode,
    String responseMessage, List<UserInfo> userInfos);
