Overview

IM terminal users need to obtain the latest messages at any time. However, due to the limited performance and battery power of mobile devices, when the app is running in the background, IM recommends that you use the system-grade push channels provided by vendors for message notifications to avoid excessive resource consumption caused by maintaining a persistent connection. Compared with third-party push, system-grade push channels provide more stable system-grade persistent connections, enabling users to receive push messages at any time and greatly reducing resource consumption.

IM supports Mi Push, Huawei Push, Meizu Push, vivo Push, OPPO Push, and Google FCM Push. The vendor channels used by IM demos are provided and maintained by TPNS in a unified manner. You can integrate the TPNS service or the offline push service of the desired vendor for offline push feature.
Supported vendor channels are as below:

说明：

If you need to improve the push delivery rate or implement diversified push, we recommend that you install the SDK of TPNS to enjoy the complete push service. If you use IM and TPNS at the same time, you do not need to repeatedly integrate vendor channels.

Push Channel	System Requirements	Conditions
Mi Push	MIUI	To use Mi Push, add the dependency: implementation 'com.tencent.tpns:xiaomi:1.2.1.2-release'.
Huawei Push	EMUI	To use Huawei Push, add the dependencies: implementation 'com.tencent.tpns:huawei:1.2.1.2-release' and implementation 'com.huawei.hms:push:5.0.2.300'.
Google FCM Push	Android 4.1 and later versions	To use mobile phones installed with Google Play Services outside the Chinese mainland, add the dependency: implementation 'com.google.firebase:firebase-messaging:20.2.3'.
Meizu Push	Flyme	To use Meizu Push, add the dependency: implementation 'com.tencent.tpns:meizu:1.2.1.2-release'.
OPPO Push	ColorOS	Not all OPPO models and versions support OPPO Push. To use OPPO Push, add the dependency: implementation 'com.tencent.tpns:oppo:1.2.1.2-release'.
vivo Push	Funtouch OS	Not all vivo models and versions support vivo Push. To use vivo Push, add the dependency: implementation 'com.tencent.tpns:vivo:1.2.1.2-release'.

Here, “offline” means that the app is closed by the system or user without logging out. In such cases, if you want to receive IM SDK message reminders, you can integrate IM offline push.

注意：

• Users who have logged out or have been forced offline will not receive any message notifications.
• For Mi and Huawei vendors, if a ChannelID has been configured on the official website of the vendor developer, you need to configure the same ChannelID on the IM console. Otherwise, push may fail. If you do not configure the ChannelID, you will be limited by the frequency limit.

The process of implementing offline message push is as follows:

1. Register with the vendor, apply to enable the push service and create an app. Obtain information such as AppID, AppKey, and AppSecret.
2. Integrate the push SDK provided by the vendor with your project. Use the vendor’s console to test notification messages to ensure the SDK was integrated properly.
3. Log in to the IM console and specify the push certificate and relevant information. The IM server will generate a unique certificate ID for each certificate.
4. Send your certificate ID and device information to IM server.

When the client app is killed by the system or user without IM logout, the IM server will push the messages sent by other accounts through vendor’s channel.

Mi Push

Configuring the push certificate

1. Access the Mi open platform website to register an account and pass the developer verification. Log in to the console of the Mi open platform, choose App Service > Push Service, and create a Mi Push service app. Take note of the Primary package name, AppID, and AppSecret information.

2. Log in to the IM console and click the target app card to go to the basic configuration page of the app. Click Add Certificate under Android Platform Push Settings. Use the information you obtained in step 1 to configure the following parameters:

   • Push Platform: choose Mi.
   • SDKAppID: the primary package name of the Mi Push service app.
   • AppID: enter the AppID you got from Mi Push.
   • AppSecret: enter the AppSecret you got from Mi Push.
   • Response after Click: the event to take place after the notification bar message is clicked. Valid values include Open app, Open webpage, and Open specified in-app page. For more information, see Configuring Click Event.
   • Open app* or Open specified in-app page allows [custom content pass through(#xiaomi_custom).
     
     Click Confirm to save the information. Take note of the ID of the certificate. Certificate information takes effect within 10 minutes after you save it.
     

Integrating the push SDK

1. Add the Mi dependency: implementation 'com.tencent.tpns:xiaomi:1.2.1.2-release'.
2. Refer to the Integration Guide for Mi Push, and use the Mi console to test notification messages to ensure that the SDK was integrated properly.
3. Call MiPushClient.registerPush to initialize the Mi Push service. After successful registration, you will receive the registration result in onReceiveRegisterResult of the custom BroadcastReceiver. regId is the unique identifier of the current app on the current device. After successful login to the IM SDK, you need to call setOfflinePushConfig to report the certificate ID and regId to the IM server.

After the certificate ID and regId are successfully reported, the IM server sends messages via Mi Push notifications to the user when the app has been killed but the user has not logged out of IM.

Configuring click events

You can select one of the following events: Open app, Open webpage, or Open specified in-app page.

Open app

If you choose Open app, the onNotificationMessageClicked method of Mi will be called back, and the app itself can process app opening in this method.

Open webpage

You need to select Open webpage when adding a certificate and enter a URL that starts with either http:// or https://, such as https://intl.cloud.tencent.com/document/product/269?from_cn_redirect=1.

Open specified in-app page

1. In manifest, configure the intent-filter of the Activity to be opened. See the sample code below. You can refer to AndroidManifest.xml of the demo:

   <activity
   android:name="com.tencent.qcloud.tim.demo.chat.ChatActivity"
   android:launchMode="singleTask"
   android:screenOrientation="portrait"
   android:windowSoftInputMode="adjustResize|stateHidden">
   <intent-filter>
   <action android:name="android.intent.action.VIEW" />
   <data
    android:host="com.tencent.qcloud.tim"
    android:path="/detail"
    android:scheme="pushscheme" />
   </intent-filter>
   </activity>

2. Obtain the intent URL, as shown below:

   Intent intent = new Intent(this, ChatActivity.class);
   intent.setData(Uri.parse("pushscheme://com.tencent.qcloud.tim/detail"));
   intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
   String intentUri = intent.toUri(Intent.URI_INTENT_SCHEME);
   Log.i(TAG, "intentUri = " + intentUri);
   // Print results
   intent://com.tencent.qcloud.tim/detail#Intent;scheme=pushscheme;launchFlags=0x4000000;component=com.tencent.qcloud.tim.tuikit/com.tencent.qcloud.tim.demo.chat.ChatActivity;end

3. Select Open specified in-app page when adding a certificate and enter the result above.
   

Custom content pass through

Select Open app or Open specified in-app page in Response after Click when adding a certificate to support custom content pass through.

Step 1. Set custom content (sender)
Set the custom content for the notification bar message before sending the message.

• Below is a simple example on the Android platform. You can also refer to the corresponding logic in the sendMessage() method in the ChatManagerKit.java class in the TUIKit:

  JSONObject jsonObject = new JSONObject();
  try {
  jsonObject.put("extKey", "ext content");
  } catch (JSONException e) {
  e.printStackTrace();
  }
  String extContent = jsonObject.toString();
  V2TIMOfflinePushInfo v2TIMOfflinePushInfo = new V2TIMOfflinePushInfo();
  v2TIMOfflinePushInfo.setExt(extContent.getBytes());
  V2TIMManager.getMessageManager().sendMessage(v2TIMMessage, userID, null, V2TIMMessage.V2TIM_PRIORITY_DEFAULT, false,  v2TIMOfflinePushInfo, new V2TIMSendCallback<V2TIMMessage>() {
  @Override
  public void onError(int code, String desc) {}
  @Override
  public void onSuccess(V2TIMMessage v2TIMMessage) {}
  @Override
  public void onProgress(int progress) {}
  });

• For information on configurations for the IM server, refer to the OfflinePushInfo Format Example.

Step 2. Set custom content (receiver)

• If you selected Open app in Response after Click when adding a certificate, clicking the notification bar message triggers the onNotificationMessageClicked(Context context, MiPushMessage miPushMessage) callback. The custom content can be obtained from miPushMessage. You can refer to the parsing implementation in XiaomiMsgReceiver.java.

  Map extra = miPushMessage.getExtra();
  String extContent = extra.get("ext");

• If you selected Open specified in-app page in Response after Click when adding a certificate, MiPushMessage, which is the object that encapsulates the message, is passed to the client through Intent. The client then obtains the custom content from Activity. You can refer to the implementation of the parseOfflineMessage(Intent intent) method in the OfflineMessageDispatcher.java class.

  Bundle bundle = getIntent().getExtras(); 
  MiPushMessage miPushMessage = (MiPushMessage)bundle.getSerializable(PushMessageHelper.KEY_MESSAGE); 
  Map extra = miPushMessage.getExtra(); 
  String extContent = extra.get("ext");

Huawei Push

Configuring the push certificate

1. Access the official website of the Huawei Developers Alliance, register an account, and pass the developer verification. Log in to the console of the Huawei Developers Alliance, choose App Service > Development Service > PUSH, and create a Huawei push service app. Take note of the Package name, APP ID, and APP SECRET.

2. Log in to the IM console and click the target app card to go to the basic configuration page of the app. Click Add Certificate under Android Platform Push Settings. Use the information you obtained in step 1 to configure the following parameters:

String value = bundle.getString("ext"); 

OPPO Push

Configuring the push certificate

1. Refer to How to enable OPPO Push for instructions on how to enable OPPO Push. Go to OPPO push platform > Configuration Management > App Configuration to view detailed app information. Take note of AppId, AppKey, AppSecret, and MasterSecret.
   

2. The official OPPO documentation states that ChannelIDs are required for push messages on OPPO Android 8.0 and above. Therefore, create a ChannelID for your app. Below is a sample code that creates a ChannelID called tuikit:

   public void createNotificationChannel(Context context) {
        // Create the NotificationChannel, but only on API 26+ because
        // the NotificationChannel class is new and not in the support library
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                CharSequence name = "oppotest";
                String description = "this is opptest";
                int importance = NotificationManager.IMPORTANCE_DEFAULT;
                NotificationChannel channel = new NotificationChannel("tuikit", name, importance);
                channel.setDescription(description);
                // Register the channel with the system; you can't change the importance
                // or other notification behaviors after this
                NotificationManager notificationManager = context.getSystemService(NotificationManager.class);
                notificationManager.createNotificationChannel(channel);
        }
   }

3. Log in to the IM console and click the target app card to go to the basic configuration page of the app. Click Add Certificate under Android Platform Push Settings. Use the information you obtained in step 1 to configure the following parameters:

  try {
  jsonObject.put("extKey", "ext content");
  } catch (JSONException e) {
  e.printStackTrace();
  }
  String extContent = jsonObject.toString();
  V2TIMOfflinePushInfo v2TIMOfflinePushInfo = new V2TIMOfflinePushInfo();
  v2TIMOfflinePushInfo.setExt(extContent.getBytes());
  V2TIMManager.getMessageManager().sendMessage(v2TIMMessage, userID, null, V2TIMMessage.V2TIM_PRIORITY_DEFAULT, false,  v2TIMOfflinePushInfo, new V2TIMSendCallback<V2TIMMessage>() {

  }
  String extContent = jsonObject.toString();
  V2TIMOfflinePushInfo v2TIMOfflinePushInfo = new V2TIMOfflinePushInfo();
  v2TIMOfflinePushInfo.setExt(extContent.getBytes());
  V2TIMManager.getMessageManager().sendMessage(v2TIMMessage, userID, null, V2TIMMessage.V2TIM_PRIORITY_DEFAULT, false,  v2TIMOfflinePushInfo, new V2TIMSendCallback<V2TIMMessage>() {
  @Override
  public void onError(int code, String desc) {}
  @Override
  public void onSuccess(V2TIMMessage v2TIMMessage) {}
  @Override
  public void onProgress(int progress) {}
  });

• For information on configurations for the IM server, refer to the OfflinePushInfo Format Example.

Step 2. Set custom content (receiver)

Clicking a notification bar message triggers a callback of onNotificationClicked(Context context, MzPushMessage mzPushMessage), which is part of the Meizu Push SDK. The custom content can be obtained from the value of mzPushMessage .

String extContent = mzPushMessage.getSelfDefineContentString();

Alternatively, the client can obtain the custom content from the opened Activity. You can refer to the parseOfflineMessage(Intent intent) implementation method in the OfflineMessageDispatcher.java class.

Bundle bundle = getIntent().getExtras();
String extContent = bundle.getString("ext"); 

Google FCM Push

Integrating the SDK

1. Register with Firebase Cloud Messaging and create an app.
   
2. Log in to the Firebase console and click your app card to go to the app configuration page. Click on the right side of Project Overview, choose Project Settings > Service Account, and click Generate New Private Key to generate a new private key file.
   
3. Log in to the Tencent Cloud IM console and click the target app card to go to the basic configuration page of the app. Click Add Certificate under Android Platform Push Settings. Upload the private key file obtained in Step 2.
   
4. Click Confirm to save the information. Take note of the ID of the certificate. Certificate information takes effect within 10 minutes after you save it.
   

Integrating the push SDK

1. Add the FCM dependency: implementation 'com.google.firebase:firebase-messaging:20.2.3'.
2. Refer to Firebase Cloud Messaging to set up Firebase. Refer to the FCM Testing Guide to test notification messages to ensure that FCM was integrated properly.
3. After calling FirebaseInstanceId.getInstance().getInstanceId(), you can obtain the token in the callback. The token is the unique identifier of the current app. After successful login to the IM SDK, you need to call setOfflinePushConfig to report the certificate ID and token to the IM server.

After the certificate ID and regId are successfully reported, the IM server sends messages via FCM Push notifications to the user when the app has been killed but the user has not logged out of IM.

Custom content pass through

Step 1. Set custom content (sender)
Set the custom content for the notification bar message before sending the message.

• Below is a simple example on the Android platform. You can also refer to the corresponding logic in the sendMessage() method in the ChatManagerKit.java class in the TUIKit:

  JSONObject jsonObject = new JSONObject();
  try {
  jsonObject.put("extKey", "ext content");
  } catch (JSONException e) {
  e.printStackTrace();
  }
  String extContent = jsonObject.toString();
  V2TIMOfflinePushInfo v2TIMOfflinePushInfo = new V2TIMOfflinePushInfo();
  v2TIMOfflinePushInfo.setExt(extContent.getBytes());
  V2TIMManager.getMessageManager().sendMessage(v2TIMMessage, userID, null, V2TIMMessage.V2TIM_PRIORITY_DEFAULT, false,  v2TIMOfflinePushInfo, new V2TIMSendCallback<V2TIMMessage>() {
  @Override
  public void onError(int code, String desc) {}
  @Override
  public void onSuccess(V2TIMMessage v2TIMMessage) {}
  @Override
  public void onProgress(int progress) {}
  });

• For information on configurations for the IM server, refer to the OfflinePushInfo Format Example.

Step 2. Set custom content (receiver)
When the notification bar message is clicked, the client can obtain the custom content from the corresponding Activity. You can refer to the parseOfflineMessage(Intent intent) implementation method in the OfflineMessageDispatcher.java class.

Bundle bundle = getIntent().getExtras();
String value = bundle.getString("ext"); 

Setting Custom iOS Push Alert Sound

When calling sendMessage to send messages, use the setIOSSound API in V2TIMOfflinePushInfo to set the sound for push notifications on iOS devices.

Setting Custom Display for Offline Push

When calling sendMessage to send messages, use setTitle and setDesc in V2TIMOfflinePushInfo to set the title and content of notification bar messages respectively.

FAQs

How to set a custom sound for push notifications on Android phones?

Currently, most vendors do not support setting a custom sound for push notifications, therefore it is not supported by the IM SDK.

Why do OPPO mobile phones fail to receive offline push messages?

This generally occurs for the following reasons:

• According to requirements on the official website of OPPO Push, ChannelID must be configured on OPPO mobile phones that run Android 8.0 or later versions. Otherwise, push messages cannot be displayed. For the configuration method, see OPPO Push configuration.
• The custom content in the message for pass-through offline push is not in the JSON format. As a result, OPPO mobile phones do not receive the push message.

Why doesn’t offline push work for custom messages?

The offline push for custom messages is different from that for ordinary messages. As we cannot parse the content of custom messages, the push content cannot be determined. Therefore, by default, custom messages are not pushed offline. If you need offline push for custom messages, you need to set the desc field in offlinePushInfo during sendMessage, and the desc information will be displayed by default during push.
