Android 构建错误 com.google.firebase :firebase-core:17. 0.0

Question

我在构建时遇到了问题。我添加了 build firebase core 16.0.0，但是在构建时，这是 build firebase core 17.0.0。为什么它构建 17.0.0.I 检查 android https://firebase.google.com/docs/android/setup#available_libraries ，现在是 16.0.0 版，我必须删除构建项目，但这并不成功。 你能帮助我吗？谢谢。

当我增加版本构建时

  classpath 'com.google.gms:google-services:4.0.1' // google-services plugin

和

Answer 1

首先，添加 build.gradle 文件，以包含 google-services 插件和 Google 的 Maven 存储库:

buildscript {
// ...
dependencies {
    // ...
    classpath 'com.google.gms:google-services:4.0.1' // google-services 
plugin
}
}

 allprojects {
// ...
repositories {
    // ...
    maven {
        url "https://maven.google.com" // Google's Maven repository
    }
}
 }

在文件底部添加 apply plugin 行以启用 Gradle 插件:

apply plugin: 'com.android.application'

android {
 // ...
 }

 dependencies {
  // ...
 implementation 'com.google.firebase:firebase-core:16.0.0'

  // Getting a "Could not find" error? Make sure you have
  // added the Google maven respository to your root build.gradle
  }

  // ADD THIS AT THE BOTTOM
  apply plugin: 'com.google.gms.google-services'

您还应该为要使用的 Firebase SDK 添加依赖项。我们建议从 com.google.firebase:firebase-core

开始
