Java 无法使用Play Core Library提供的应用程序内更新支持更新应用程序

我只是想实现GooglePlayCoreLibraryAPI提供的应用内更新服务

在将更新版本的应用程序发布到内部测试轨道后，我在play store中获得更新版本的应用程序

但是，我无法在同一页上看到“更新”按钮

此外，应用程序被禁用，以根据代码的实现进行更新。 请帮我解决这个问题

private AppUpdateManager appUpdateManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        appUpdateManager = AppUpdateManagerFactory.create(this);
        InAppUpdate.setImmediateUpdate(appUpdateManager, this);
    }

    @Override
    protected void onResume() {
        super.onResume();
        InAppUpdate.setImmediateUpdateOnResume(appUpdateManager, this);
    }
}

及

public class InAppUpdate {

    public static int REQUEST_APP_UPDATE = 302;

    public static void setImmediateUpdate(AppUpdateManager appUpdateManager, Activity activity) {

        appUpdateManager

                            // Checks that the platform will allow the specified type of update.
                            if ((appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE)
                                    && appUpdateInfo.isUpdateTypeAllowed(AppUpdateType.IMMEDIATE)) {
