That's what you specified in the intent filter -- you claim to support every HTTP(S) URL everywhere regardless of MIME type, host, or anything else. That's why the intent filter is evil. > 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. Then, if the sender uses Intent.createChooser(), like the Browser app does, you will appear as a viable option. 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.
