无法使用Play Core库提供的支持应用程序内更新来更新应用程序

Question

我只是尝试在google play核心库API提供的应用程序更新服务中实现。

在发布了较新版本的应用程序后进行了内部测试。我在play store中获得了更新版本的应用程序，如图1所示。但是，我无法看到“更新”按钮在同一页上，正如屏幕上的-2。另外，应用程序是禁用的，以更新根据代码的实现。请帮我处理这件事。谢谢。屏幕肖像1屏幕肖像2

`

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);
}
}

和

请确保设备中安装的app是比推送发布的app更低的版本。
