Question

Is there a default activity in Android that handles the opening of files? For example in Quickoffice, you can open a file, but it doesn’t allow you to navigate directories. This might be an old-school type of request, but in an application I’m developing, I want to send an Intent to request the user to select a file. My application will then process that file.

Ideally, this will end up as a Settings configuration for a service that will be used by other applications.

Edit: I’m browsing the documentation at http://developer.android.com/guide/topics/data/data-storage.html, but in my case, I want to store and retrieve data that doesn’t fit in any of the categories:

• Music/ – Media scanner classifies all media found here as user music.
• Podcasts/ – Media scanner classifies all media found here as a podcast.
• Ringtones/ – Media scanner classifies all media found here as a ringtone.
• Alarms/ – Media scanner classifies all media found here as an alarm sound.
• Notifications/ – Media scanner classifies all media found here as a notification sound.
• Pictures/ – All photos (excluding those taken with the camera).
• Movies/ – All movies (excluding those taken with the camcorder).
• Download/ – Miscellaneous downloads.

For the types of files managed by MediaStore (e.g., MIME type audio/*), ACTION_PICK works. For arbitrary files, no.
