JAVAlang.RuntimeException:无法实例化服务com。桑里德。搭档JAVAMyFirebaseMessagingService

Question

我正在使用Firebase消息，当我从Firebase控制台收到通知时，我的应用程序关闭，但出现此异常。有人能建议我应该怎么做吗？我正在与此问题斗争两个多小时了

我的Firebase Messagin版本是firebase_messaging：^6.0.16

我对firebaseMessaging的依赖性是implementation'com.google.firebase:firebase消息：20.2.3'

JAVAlang.RuntimeException:无法实例化服务com。桑里德。搭档JAVAMyFirebaseMessagingService:java。lang.ClassNotFoundException:在路径：DexPathList[[zip file”/system/framework/org.apache.http.legacy.boot.jar]，zip文件“/data/app/com.samridh.partner-amekbtimigalfobi3aueg=/base.apk”]上找不到类“com.samridh.partner.java.MyFirebaseMessagingService”，nativeLibraryDirectories=[/data/app/com.samridh.partner-amekbtimigalfobi3aueg==/lib/arm64，/data/app/com.samridh.partner-amekbtimigalfobi3aueg==/base.apk！/lib/arm64-v8a，/system/lib64]]

我的Android清单。xml文件是

还有我的申请。kt文件是

package com.samriddh.partner

import io.flutter.plugin.common.PluginRegistry
import io.flutter.plugin.common.PluginRegistry.PluginRegistrantCallback
import io.flutter.plugins.GeneratedPluginRegistrant
import io.flutter.plugins.firebasemessaging.FlutterFirebaseMessagingService

class Application : FlutterApplication(), PluginRegistrantCallback {

    override fun onCreate() {
        super.onCreate()
        FlutterFirebaseMessagingService.setPluginRegistrant(this);
    }

    override fun registerWith(registry: PluginRegistry?) {
        io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin.registerWith(registry?.registrarFor("io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin"));
    }
}

Answer 1

检查顶部的包装是否正确。前任。

package com.samriddh.partner

如果你从一个例子中复制/粘贴（比如dummy me），它还有一些其他的包。

package com.google.firebase.quickstart.fcm.kotlin

Answer 2

错误是告诉你Android找不到你声明的服务与完整的类名"com.samriddh.partner.java.MyFirebasMessagingService"。要么你从未添加过这个类，要么你告诉Android清单中的错误名称。
