java找不到安卓。拱生命周期：扩展：2.1.0。所需人员：项目：app>com。贝宝。签出：安卓sdk:0.1.0

Question

我正在尝试从下面的链接在Android项目中安装paypalcheckout sdk

https://developer.paypal.com/docs/business/native-checkout/安卓/

我还将其添加到gradle应用程序模块文件中的依赖项中 实现'com。贝宝。签出：安卓 sdk:0.2.0'&；重建项目，但它将无法生成

项目中的gradle文件代码

allprojects {
repositories {
    jcenter()
    google()
    mavenCentral()
    maven {
        url "https://maven.google.com"
    }
    maven {
        url  "https://cardinalcommerceprod.jfrog.io/artifactory/安卓"
        credentials {
            // Be sure to add these non-sensitive credentials in order to retrieve dependencies from
            // the private repository.
            username 'paypal_sgerritz'
            password 'AKCp8jQ8tAahqpT5JjZ4FRP2mW7GMoFZ674kGqHmupTesKeAY2G8NcmPKLuTxTGkKjDLRzDUQ'
        }
    }
    maven { url 'https://maven.fabric.io/public' }
}

}

当我构建安卓项目时，它会显示错误

Execution failed for task ':app:preDebugBuild'.
> Could not resolve all files for configuration ':app:debugRuntimeClasspath'.
   > Could not find 安卓.arch.lifecycle:extensions:2.1.0.

Possible solution:
 - Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

我不熟悉安卓系统。建议我一些解决方法

您可能缺少在应用程序级生成中添加依赖项的功能。格拉德尔

implementation 'android.arch.lifecycle:extensions:2.1.0'
implementation 'android.arch.lifecycle:runtime:2.1.0'
