Use this SDK to add instant messaging capabilities to your Android app. By connecting to a self-hosted OpenIM server, you can quickly integrate instant messaging capabilities into your app with just a few lines of code.
The underlying SDK core is implemented in OpenIM SDK Core. Using gomobile, it can be compiled into an AAR file for Android integration. Android interacts with the OpenIM SDK Core through JSON, and the SDK exposes a re-encapsulated API for easy usage. In terms of data storage, Android utilizes the SQLite layer provided internally by the OpenIM SDK Core.

For the SDK reference, see https://doc.rentsoft.cn/sdks/quickstart/android.

The following examples demonstrate how to use the SDK.
package io.openim.android.sdk; InitConfig initConfig = new InitConfig("Your IM server address",
"Your IM server socket address", getStorageDir()); //Storage path
initConfig.isLogStandardOutput = true;
///IM ๅๅงๅ
OpenIMClient.getInstance().initSDK('Your Application',
initConfig, IMEvent.getInstance().connListener);Note1: You need to set up the listeners first and then log in.
// Set listener
//User Profile Change Listener
OpenIMClient.getInstance().userInfoManager.setOnUserListener(new OnUserListener() { });
//Message-related Listener
OpenIMClient.getInstance().messageManager.setAdvancedMsgListener(new OnAdvanceMsgListener() {});
//Friendship Status Change Listener
OpenIMClient.getInstance().friendshipManager.setOnFriendshipListener(new OnFriendshipListener() {});
//Conversation-related Listener
OpenIMClient.getInstance().conversationManager.setOnConversationListener(new OnConversationListener() {});
//Group-related Listener
OpenIMClient.getInstance().groupManager.setOnGroupListener(new OnGroupListener() { });
// Retrieve the profile of the currently logged-in user
OpenIMClient.getInstance().login(new OnBase<String>() {
@Override
public void onError(int code, String error) {
IView.err(error);
}
@Override
public void onSuccess(String data) {
//Cache login information and start a delightful chat
}
}, userID, token);To log into the IM server, you need to create an account and obtain a user ID and token. Refer to the access token documentation for details.
OpenIM makes it easy to send and receive messages. By default, there is no restriction on having a friend relationship to send messages (although you can configure other policies on the server). If you know the user ID of the recipient, you can conveniently send a message to them.
//Send
Message msg = OpenIMClient.getInstance().messageManager.createTextMessage("hello openim");
OpenIMClient.getInstance().messageManager.sendMessage(new OnMsgSendCallback() {
@Override
public void onError(int code, String error) {
// Failed to send message โ
}
@Override
public void onProgress(long progress) {
//Sending...
}
@Override
public void onSuccess(Message message) {
// Message sent successfully โ๏ธ
}
}, msg, userID, groupID, null);
//Receive
OpenIMClient.getInstance().messageManager.setAdvancedMsgListener(new OnAdvanceMsgListener(){
@Override
public void onRecvNewMessage(Message msg) {
// Received new message ๐จ
}
}๏ผYou can find a demo Android app that uses the SDK in the open-im-android-demo repository.
