Flutter：java.lang.NoClassDefFoundError：解析失败：Lcom/google/firebase/iid/FirebaseInstanceId

Question

SDK：颤振

我们在我们的应用程序中使用 Flutter 和 Firebase 消息传递。 除此之外，我们还使用 plain_notification_token 来获取 Android 的 FCM 令牌和 iOS 的 APNS 令牌。 将 Gradle 升级到 4.2.2 时出现此错误。

这是 build.gradle 文件，在将 Gradle 版本从 3.x 更新到 4.2.2 后，Flutter 项目中开始出现问题。 我能够编译应用程序，但应用程序在运行时崩溃。

构建.gradle

buildscript {
    ext.kotlin_version = '1.5.20'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.2.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

}

allprojects {
    repositories {

        mavenCentral()
    }
    configurations.all {
        resolutionStrategy {
            forcedModules = [

            ]
        }
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Answer 1

添加

 implementation 'com.google.firebase:firebase-iid'

到您的 Android/app/build.gradle ，这应该可以解决问题。

Answer 2

实施 'com.google.firebase:firebase-iid'

在 build.gradle 中添加这一行

为我工作
