在 android studio 中实现 Firebase admin sdk 时出错

Question

当我实施 firebase 管理库时 它显示了我在下面的应用程序和项目级 gradle 文件之后提到的错误。

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.3"

    configurations {

    }

    defaultConfig {

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {


    repositories {
        google()
        jcenter()
        maven {
            url 'https://maven.google.com/'
            name 'Google'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

}

allprojects {
    repositories {
        google()
        jcenter()

    }
}

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

下面是错误信息，

在项目“app”中，解决了 Google Play 服务库依赖项 依赖于另一个确切版本（例如“[1.21.0]”，但不是 正在解决该版本。图书馆展示的行为将 不为人知。

take a look at the javadoc for FirebaseOptions Builder in the Android client library:

com.google.firebase.FirebaseOptions.Builder

Now look at the same class from the java Admin SDK (note the URL is different):

com.google.firebase.FirebaseOptions.Builder 

Answer 2

删除这个：

implementation 'com.google.firebase:firebase-admin:6.12.2'

您无法在 Android 应用中有效地使用 Firebase Admin SDK。它仅适用于在后端服务器和台式机上运行的代码。

此外，您应始终确保您的 Android 客户端库依赖项为release notes 中显示的当前版本。您的 Firebase-UI 库版本还应与其他 Firebase 库匹配。
