嗨，我在android中启动了一个新项目，并按照google docs中的说明导入了Firebase。在Android Studio 3.0.1中，一切都很完美。现在，我将Android Studio更新至3.2.1。现在，重新编译相同的代码，并得到

我的项目级别爬虫是：

buildscript {

    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath 'com.google.gms:google-services:4.0.1'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        google()
    }
}

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

应用程序级别Gradle是：

apply plugin: 'com.android.application'

    defaultConfig {
        applicationId "com.arafa.sms"

}

这里是什么问题！请帮帮我！

Answer 1

我有同样的问题，似乎Google回购缺少此依赖项。我检查了repository，并且gms文件夹中没有发布的任何版本。

作为快速解决方案，我添加了另一个存储库：

repositories {
    maven { url 'https://dl.bintray.com/android/android-tools' }
}

编辑：由于这只是临时解决方案，我认为这是一种解决方法，因此我可以继续进行开发。当Google存储库中将包含这种依赖关系或我们知道他们将其移到何处时，我将在以后删除该依赖关系。

Answer 2

尝试将另一个Maven存储库添加到项目gradle文件中。例如：

allprojects {
    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

如果这样做不起作用，则可以将OneSignal gradle插件（也添加到项目的gradle中）来解决问题（as suggested in this answer）。

apply plugin: 'com.onesignal.androidsdk.onesignal-gradle-plugin'
