Android的 - 菜单项添加到Android内置的应用程序？

我想一个菜单选项添加到Android摄像头应用程序。这可能使用目前的SDK办？

I'd like to add a menu option to the Android camera app. Is this possible to do using the current SDK?

感谢。

编辑：确定，我知道我需要添加一个意图过滤器标签在我的活动。但我不知道我应该把MIME类型。我希望能够如果用户选择的菜单选项来处理直播相机previews。所以，我该怎么投入的意图过滤器的类型标签？

此外，我想我不会使用替代或选择的，替代的范畴，因为我要处理的整个意图是什么？

Edit : Ok I know I need to add an intent-filter tag in my activity. But I don't know what I should put in the mime type. I want to be able to process the live camera previews if the user selects the menu option. So what do I put into the type tag of the intent-filter?

Also I suppose I won't be using ALTERNATIVE or SELECTED-ALTERNATIVE for the category as I want to deal with the whole intent?

再次感谢。
