添加依赖项
Google Pay API 是 Google Play 服务的一部分，因此您只需要导入 Google Play 服务库即可取得所有需要的组件。或者，您也可以选择您想自行编译的 API。
要导入整个 Google Play 服务库，请参阅设置 Google Play 服务。
如果您仅希望选择性地编译您需要的 API，请打开应用模块中的 build.gradle 文件，并将以下内容添加到依赖项区块中：
dependencies {
implementation 'com.google.android.gms:play-services-wallet:18.1.3'
implementation 'com.android.support:appcompat-v7:24.1.1'
}
上面提供的每个版本都是最新版 Google Pay API 库所需的最低版本。您可以为您的应用选择版本较高的依赖项。如需了解最新的 Google Pay API 版本信息，请参阅设置 Google Play 服务。如需了解最新的支持库信息，请参阅支持库设置。
修改您的清单
要在您的应用中启用 Google Pay，您需要将以下 Google Pay API 元数据元素添加到项目的 AndroidManifest.xml 文件的 <application> 元素中。
<meta-data
android:name="com.google.android.gms.wallet.api.enabled"
android:value="true" />
