一旦应用程序发布后，你就不能删除它，尽管未发布的应用程序可以使用“delete app”按钮删除，如下所示:

值得注意的一个例外是，虽然你不能删除应用，但如果应用未发布且终身安装量为0，谷歌Play Developer Support的人员可以删除应用。所以如果你的应用终身安装量为0，那你就很幸运了。

首先，你需要取消应用发布，并等待24小时(以允许全局统计数据更新，并确保没有最后一分钟的安装发生)。假设在这24小时内没有最后一分钟的安装，你可以联系谷歌Play开发者支持，看看他们是否可以删除它。

请注意，他们的0安装要求是一个硬性要求。不能有任何例外(即使你自己为了测试目的安装了应用程序)。

谷歌商店严格没有提供删除/删除生产应用程序的服务，而且您不能更改生产构建以获得最佳测试。

注意:当发布/取消发布选项移动到不同位置时，添加一个新的答案。

正如在其他答案中提到的，你不能删除应用程序。随着更新的谷歌播放控制台(测试版)，取消发布选项被移动到不同的位置:

设置->高级设置->应用程序可用性

相应地启用已发布/未发布!

Updates to reports In late May 2018, you may begin to see changes in your app's metrics based on your users' deletion of data. Some metrics are calculated based on data from users who have agreed to share their data with developers in aggregate. The metrics that we provide in the Play Console are adjusted to more closely reflect data from all of your users. However, Google will not display data that falls under certain minimum thresholds. Delete an app or game You can permanently remove draft apps or games from your Play Console. You can also delete: Published apps or games that haven't been installed on any devices Published apps or games that no users are entitled to re-install In these cases, contact our support team to request that your app's or game's data be permanently deleted.

选择“Store presence”，然后选择“Pricing Distribution”，然后从“App Availability”中选择“Unpublish”。
