可以与其他应用程序交互的Android服务

Question

So I'm building an app that has the ability to run in the background and can potentially interact with other components of the OS.

Let's say you're navigating through your file manager, my app would want to add an additional action to what you can normally do with the file manager. The same thing can happen when say you're browsing with a browser, you have one additional action you can do. I've been looking at intentservices and bound services.

Can any body tell me if this is doable? Yes? No? A one line explanation would be great as well.

Answer 1

This has nothing to do with services. This has everything to do with having an <intent-filter> on an <activity> that identifies what file types you support for various Intent actions, like ACTION_VIEW . Well-written apps that launch such an Intent will either:

• use the system chooser, in which case you will appear in the option in that chooser, or

• use PackageManager and queryIntentActivities() to build their own "chooser", and you will appear in its UI

Note, though, that not all apps are well-written. Some morons will only support a fixed set of apps, and there is nothing you can do about that.
