Android intent filter for a particular file extension?

Question

I want to be able to download a file with a particular extension from the \'net, and have it passed to my application to deal with it, but I haven\'t been able to figure out

Answer 1

I've been trying to get this to work for ages and have tried basicly all the suggested solutions and still cannot get Android to recognise specific file extensions. I have an intent-filter with a "*/*" mimetype which is the only thing that seems to work and file-browsers now list my app as an option for opening files, however my app is now shown as an option for opening ANY KIND of file even though I've specified specific file extensions using the pathPattern tag. This goes so far that even when I try to view/edit a contact in my contacts list Android asks me if I want to use my app to view the contact, and that is just one of many situations where this occurs, VERY VERY annoying.

Eventually I found this google groups post with a similar question to which an actual Android framework engineer replied. She explains that android simply does not know anything about file-extensions, only MIME-types (https://groups.google.com/forum/#!topic/android-developers/a7qsSl3vQq0).

So from what I've seen, tried and read, Android simply cannot distinguish between file-extensions and the pathPattern tag is basicly a gigantic waste of time and energy. If you are fortunate enough to only need files of a certain mime-type (say text, video or audio), you can use an intent-filter with a mime-type. If you need a specific file-extension or a mime-type not known by Android however then you're out of luck.

If I'm wrong about any of this please tell me, so far I've read every post and tried every proposed solution I could find but none have worked.

I could write another page or two about how common these kinds of things seem to be in Android and how screwed up the developer experience is, but I'll save you my angry rantings ;). Hope I saved someone some trouble.
