Gmail will pass on the MIME type for the attachment unimpeded), the filter will match. But so long as the provider states your MIME type (E.g. The odd scheme out is 'content', for which the extension is not available to the filter. I haven't included other schemes like 'http' here, but they will probably work fine on all these filters. This isn't perfect, but is the only way to match the behaviour of file managers like ES File Explorer, and it is limited to intents where the URI/file extension matches. The global mime type pattern match will match all types so long as the file extension matches. The path patterns do apply, for 'file' scheme intents. The following filters get pretty close to sensible behaviour. The parser code is the other relevant piece of the puzzle. The intent filter implementation has logic that almost defies description. The best, and given the strange logic, possibly the only real documentation is the source code. There's a lot of misinformation on this topic, not least from Google's own documentation.

Having an app like Linda File Manager on your phone resisters itself generically allowing you to download any file type. I should note that this alone does not allow you to download this filetype in a browser, since this only registers with the file scheme. kdb file in an app like Linda File Manager, my app shows up as an option. For a more detailed discussion of this issue and a workaround see hereįinally, according to the Android documentation, both host and scheme attributes are required for the pathPattern attribute to work, so just set that to the wildcard to match anything. This pattern will fail to match paths that contain a.

* is not a greedy match like you would expect if this was a regular expression. These strings require double escaping, so \\. * at the beginning matches any squence of characters. PathPattern is where you specify what extension you want to match (in this example. MimeType can be set to */* to match any mime type. The scheme of file indicates that this should happen when a local file is opened (rather than protocol like HTTP). Here is how I defined my activity in my AndroidManifest.xml to get this to work.
