我应该更新哪个build.gradle文件以在React原生Android项目中添加结构数字

我正在按照说明将Twitter结构数字添加到我的Android React本机应用程序中，并在数字步骤中更新build.gradle文件。查看该项目，我在我的

/android

根目录中看到一个

build.gradle

文件，在我的

/android/app

目录中也看到一个

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

如果我比较Digits示例中显示的示例gradle文件，它似乎是两个文件的组合。我应该编辑哪一个。如果其中一个文件缺少示例中的一些配置，我是否应该添加它？例如，说明中说要向buildscript.respositories和repositories添加一个maven url，这建议我在我的android根目录中更新build.gradle，因为它有一个buildscript配置和一个allprojects.repositories节点。但是，它没有依赖项节点、android节点或插件，这些东西都在另一个build.gradle文件中，该文件没有respositories节点。我是否应该将指令中的更改拆分为两个build.gradle文件

/**
 * The react.gradle file registers a task for each build variant (e.g. bundleDebugJsAndAssets
 * and bundleReleaseJsAndAssets).
 * These basically call `react-native bundle` with the correct arguments during the Android build
 * cycle. By default, bundleDebugJsAndAssets is skipped, as in debug/dev mode we prefer to load the
 * bundle directly from the development server. Below you can see all the possible configurations
 * and their defaults. If you decide to add a configuration block, make sure to add it before the
 * `apply from: "../../node_modules/react-native/react.gradle"` line.
 *

 *   // the name of the generated asset file containing your JS bundle
 *   bundleAssetName: "index.android.bundle",

查看build.gradle中的注释会让我相信依赖项应该放在app目录中的build.gradle文件中

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

我正在使用附近的服务API做一些事情，并将依赖项放在应用程序目录的build.gradle中，一切正常
