I'm working on a WP8 app that will utilize the camera for a feature. 我正在开发一款WP8应用，它将利用相机拍摄一个功能。 I've read that, as of GDR2, you can now change which app opens with the camera button , but: 我已经读过，从GDR2开始，您现在可以使用相机按钮更改打开的应用程序，但是：

it appears that an app needs to be specially written to be used like this; 似乎应用程序需要专门编写才能像这样使用; not every photo or camera app can be configured to launch when you press the Camera button. 并非所有照片或相机应用程序都可以配置为在按下“相机”按钮时启动。

Question: What do I need to do in my app for it to become an available option in the "Pressing the camera button opens: " drop down when navigating to Settings -> Applications -> photos + camera? 问题：在我的应用程序中，我需要做什么才能成为“按相机按钮打开时：”导航到设置 - >应用程序 - >照片+相机时的下拉菜单？

Additionally , part 2 of this question would be (if part 1 is possible), when the application is launching, can I determine if the user opened it via the camera button (so that I could go straight to my camera feature)? 此外，这个问题的第2部分是（如果第1部分是可能的），当应用程序启动时，我可以确定用户是否通过相机按钮打开它（这样我可以直接进入我的相机功能）？

I've seen this article but it only describes how to use and handle the shutter button, it doesn't mention how to allow this button to open the app . 我已经看过这篇文章，但它只描述了如何使用和处理快门按钮，它没有提到如何允许此按钮打开应用程序 。

Has anyone been able to accomplish this? 有没有人能够做到这一点？

This thread ( http://forums.wpcentral.com/windows-phone-8/234751-changing-default-camera-app.html ) seems to suggest that only manufacturers can create apps that can do this. 这个主题（ http://forums.wpcentral.com/windows-phone-8/234751-changing-default-camera-app.html ）似乎表明只有制造商才能创建可以做到这一点的应用程序。 Not sure if it's definite, but I've never heard of a 3rd party camera app that can do more than register as a lens . 不确定它是否确定，但我从来没有听说过第三方相机应用程序可以做更多注册为镜头。
