将 Google TV 打造成公共信息亭
我正在开展一个项目，我们必须在公共区域放置一台 Google TV。我正在为其构建一个应该始终运行的自定义应用程序。基本上，我们不希望有人能够退出这个特定的应用程序。在完美的世界中，路过的人应该能够使用 Google TV (Revue) 附带的键盘。我的问题是，有没有办法以编程方式锁定系统？或者我们是否需要使用只有字母数字按钮的特殊键盘？
I am working on a project where we have to put a Google TV in a public area. I am building a custom application for it that should be running all the time. Basically, we don't want someone to be able to switch out of this specific application. In a perfect world, people walking by should be able to use a keyboard that comes with the Google TV (Revue). My question is, is there a way to programmatically lock down the system? Or do we need to use a special keyboard that only has alphanumeric buttons on it?

我不是 Google TV 方面的专家，但是可以通过创建一个 Home 应用程序并将其设置为默认应用程序来在移动设备中处理此类问题。因此用户无法切换该应用程序。当然，您需要确保您的应用程序是在将默认的家庭应用程序分发给用户之前（无论如何，这是您的设备而不是用户）。我不确定 Google TV 是否有家庭意图。
I am not an expert in Google TV,but such a problem can be handled in the mobile by creating a Home application and making that as default.So the user cannot switch out the application.Of course you need to make sure that your app is the default Home app before giving it out to the user(anyways this is your device and not the users). I am not sure whether the Google TV has a home intent.
如果不创建您自己的自定义固件，目前 Google TV IIRC 还无法实现这一点。
您不仅需要这个，而且还必须获得一个与该设备兼容的键盘（不确定标准蓝牙键盘是否可以工作），然后您将遇到缺少“BACK”（返回）和“MENU”（菜单）等按钮的问题。您也许能够通过在应用程序中提供足够的导航来解决这些缺失的按钮，以避免用户需要它们。
Not without creating your own custom firmware, which at the moment is not possible for Google TV IIRC.
Not only do you need that, but you would have to get one that works with the device (not sure if a standard Bluetooth keyboard will work), and then you will run into problems with missing buttons like BACK and MENU. You might be able to engineer around those missing buttons by having adequate navigation in the app to avoid users needing them.
