SignupUrl signupUrl = androidManagementClient
                .signupUrls()
                .create()
                .setProjectId(CLOUD_PROJECT_ID)
                .setCallbackUrl(CALLBACKURL).execute();

由于 NPE 导致应用程序崩溃

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'com.google.api.services.androidmanagement.v1.AndroidManagement$SignupUrls com.google.api.services.androidmanagement.v1.AndroidManagement.signupUrls()' on a null object reference

有没有人见过这个？我已经遵循了开发的所有先决条件，目前正在关闭示例应用程序，这是崩溃的代码。可能是什么原因？

根据要求更新：

代码

EnterpriseHelperClass - 我想以编程方式执行此操作，即使我知道这可以通过快速入门指南轻松执行。

public class EnterpriseCreationHelper {
    private static final String CALLBACKURL =
            "https://play.google.com/work/adminsignup?enterpriseToken";
    private static final String TAG = "MainActivity";
    private static String CLOUD_PROJECT_ID = "******-";
    private static String SERVICE_ACCOUNT = "****@****-.iam.gserviceaccount.com";
    private static String CREDENTIALS_FILE =
            "/Users/****/appname/src/******.json";
    private static String POLICY_ID = "samplePolicy";
    private static AndroidManagement androidManagementClient;

    public EnterpriseCreationHelper(AndroidManagement androidManagementClient){
        EnterpriseCreationHelper.androidManagementClient = androidManagementClient;
    }

    public void run() throws IOException {

看起来getAndroidManagementClient正在返回一个空对象，这导致将androidManagementClient设置为空。确保您的凭据正确，并且此方法成功返回。
