Flutter: java.lang.NoClassDefFoundError: Failed resolution of: 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。与此同时，我们使用 plain_notification_token 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，问题开始出现在 Flutter 项目中。我能够编译应用程序，但应用程序在运行时崩溃。

build.gradle

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

    dependencies {

        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.8'
        classpath 'com.google.firebase:firebase-crashlytics-gradle:2.7.1'
        classpath 'com.google.firebase:perf-plugin:1.4.0'
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
    configurations.all {
        resolutionStrategy {
            forcedModules = [
                    "com.google.android.gms:play-services-vision-common:19.0.2",
            ]
        }
    }
}

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'

您的 Android/app/build.gradle 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

对我有用

Flutter: java.lang.NoClassDefFoundError: Failed resolution of: Lcom/google/firebase/iid/FirebaseInstanceId

Flutter: java.lang.NoClassDefFoundError: Failed resolution of: Lcom/google/firebase/iid/FirebaseInstanceId

java
