That is correct, yes. > That's why the intent filter is evil. "Evil" is a bit harsh, isn't it? :) After all, it's pretty much the same filter used by Browser (with the omission of about: URIs) > > Is there a way to circumvent this > > behavior in the Browser app, yet still present my app as an option > > when clicking links in email clients and the like? > > Intent filters are agnostic to the sender of the Intent, so anything in > the system could send an Intent that your intent filter will match.

I can see why the email app would invoke ResolverActivity, but why the Browser would do this for every clicked link and every entered URL is unclear to me. As mentioned, Steel doesn't do this. Setting Steel to the default URL handler will therefore, in effect, render the Browser app unusable since any click or address entry in Browser will be sent to Steel. It seems like the answer to my question is "no" then? > Furthermore, you really need to more tightly constrain that intent filter, > so it is only going to be used for MIME types you actually will support, > or only from certain sites, or something. Look at the <data> element in > the SDK documentation: Well, the MIME type of a HTTP(S) resource will be unknown until the network resource is opened, won't it? For example when I click a link in an email. Anyway, since text/html and application/xhtml+xml are among the MIME types I'm interested in, I guess it wouldn't help me if I did know the type beforehand; Browser would still pop up a chooser that contained my app along with Browser itself.
