Android管理API服务文件分配

Question

我正在测试 android 管理 API 使用本地主机作为回调 url。我遵循了此 url Android Management API Sample 之后的每一步。现在我被困在原地.. 根据本指南，我从服务帐户下载 json 文件。现在我复制那个 json 文件并保存在我项目的 app 文件夹中。这是我的 enterprise.json 文件 Screenshot of json file in android studio

我只是在位置字符串中将文件夹位置指定为 enterprise.json 这是我的代码

private static final String PROJECT_ID = "enterprise-271814";

    private static final String APP_NAME = "Device Policey Controller";

    private final AndroidManagement androidManagementClient;


    public Sample(AndroidManagement androidManagementClient) {

    }

    public void run() throws IOException {

        System.out.println("Enrollment token (to be typed on device): " + token);

        // List some of the devices for the enterprise. There will be no devices for
        // a newly created enterprise, but you can run the app again with an
        // existing enterprise after enrolling a device.

此外，我第一次使用 android 管理 api，我不知道它的正确实施。任何有这方面经验的人都可以指导我一点。我找到了很多关于此的内容，但我没有找到任何有用的教程

对于 Android，您必须将服务帐户文件存储在 assets 文件夹或 raw 文件夹中。

This thread 提供了有关根据您选择的位置将 json 数据加载到 InputStream 的多种方法的代码。
