FCM Channel Integration Guide

Operation Scenarios

FCM channels are system-level push channels provided by Google. If you use a mobile phone with the Google service framework, you can receive push notifications without opening applications. If the mobile phone ROM has no FCM, the TPNS channel will be used.

Directions

1. Get the FCM push key

1. Register the application at FireBase official website. Configure the FCM application push server key and SenderID to the TPNS Console.
2. Download the google-services.json file.
   See below:

Get the json file:

Get the server key:

Configuring Content

1. Configure the google-services.json file, as shown in the following figure:
   
2. Configure gradle to integrate the Google service.
   a) Add the following code to the dependencies node in the project-level build.gradle file:

   classpath 'com.google.gms:google-services:4.2.0'

Note: if you use a version below 4.2.0, the following message will appear: FCM Register error! java.lang.IllegalStateException: Default FirebaseApp is not initialized in this process com.qq.xg4all. Make sure to call FirebaseApp.initializeApp(Context) first.
Solution: you can add the following to string.xml under the res/values folder:
YOUR_GOOGLE_APP_ID

Add dependencies to the app-level build.gradle file

implementation 'com.tencent.tpns:fcm:[VERSION]-release'// [VERSION] is the current SDK version number.You can view the SDK version number on the SDK download page

implementation  'com.google.firebase:firebase-messaging:17.6.0'



 // In the app-level gradle file, add the following to the last line of the code and put google-services.json into the root path of your application model

apply plugin: 'com.google.gms.google-services'

Note: Google configures google-play-services (TPNS only uses it to detect whether the device supports Google services. You are recommended to use a version higher than 17.0.0; otherwise, you may not be able to register for FCM). For more information, please see documentation at: https://developers.google.com/android/guides/setup#add_google_play_services_to_your_project

Enabling FCM push

Add the following code setting before the TPNS calling registration code (XGPushManager.registerPush):

XGPushConfig.enableOtherPush(this, true);

The log of a successful FCM registration is as follows:

 E/XG_fcm: Fcm App has initialized 
 D/XG_fcm: FirebaseAPP initialization complete
 I/XG_fcm: registerPush Token is: eK0LLz43Z_U:APA91bHjyTCuX7fZ6Ye-fAojAo_l2nphA3rRtLZN98grADOZtULysxYd51pCaL5oiqyVs0Mtbfu2mBdjoeGsSq5sjbh5mCETgl2dURRy9-yNR_ZZrn6pWcvwt7CoWTY0_Q9_mreiryuI
