当 minifyEnabled=true 时不发送 Firebase 通知

Question

我这几天一直有问题。我正在使用 Firebase Cloud Messaging 向我的 Android 应用发送通知。当 minifyEnabled=false 时，通知进入发布模式。但是，当 minifyEnabled=true 时，通知不会出现。我添加到 proguard-rules.pro 文件中的任何内容仍然没有出现。有什么想法吗？

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.umit.app">

    <uses-sdk tools:overrideLibrary="com.google.zxing.client.android" />

    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:name=".umitapp"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"          
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

        <service
            android:name=".application.FirebaseMessagingService"
            android:exported="false">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT" />
            </intent-filter>
        </service>
        
        ...
        ..
        .

FirebaseMessagingService

class FirebaseMessagingService : FirebaseMessagingService() {
    
    override fun onNewToken(newToken: String) {
        super.onNewToken(newToken)
    }

    override fun onMessageReceived(remoteMessage: RemoteMessage) {
        super.onMessageReceived(remoteMessage)
        App.sendNotification(remoteMessage)
    }       
}

Answer 1

如果您将 android sdk 定位到 android - 12，我们需要使用标志 mutable / or immutable 设置挂起的 Intent，并且我们还需要更新 firebase SDK。
