1028091 - nsIExternalProtocolService lies about URI scheme support every single time

Status: RESOLVED INCOMPLETE

(Firefox for Android Graveyard :: General, defect)

Description

[:Gijs (he/him)]

STR:

0. Connect your Fx for Android app into a console for remote debugging.
1. Execute:

extProtService = Cc["@mozilla.org/uriloader/external-protocol-service;1"].getService(Ci.nsIExternalProtocolService);


extProtService.externalProtocolHandlerExists("bogus")
// true
extProtService.externalProtocolHandlerExists("noreallythisisridiculous")
// also true



A bit more digging led me to:

handlerInfo = extProtService.getProtocolHandlerInfoFromOS("thisistotallybogus", {});

handlerInfo.preferredApplicationHandler

which output:

{ /* snip'd interface stuff */ name: "Android chooser", detailedDescription: "Android's default handler application chooser" }


Which is all well and good, but this is kind of annoying. I would have expected an actual useful reply to "does someone know how to deal with this protocol", and it's essentially given me "yes" as a substitute for "maybe". :-(
