This will be follow-up (or part of) Bug 1250782. This ticket tracks adding code to https://dxr.mozilla.org/mozilla-central/source/mobile/android/services/src/main/java/org/mozilla/gecko/fxa/receivers/FxAccountDeletedService.java#40 to HTTP DELETE the relevant FxA device ID, if we can. At that point we should have access to the FxA authToken, so we can actually authenticate. I suppose this assumes the account is healthy, so we can get the authToken; if we can't, or the authentication fails, we can't make progress, so just give up. See https://bugzilla.mozilla.org/show_bug.cgi?id=1250782#c3.

Comment on attachment 8846784 [details] Bug 1254643 - Delete FxA device when Fennec Firefox Account is removed. https://reviewboard.mozilla.org/r/119790/#review122178 LGTM, patch seems to mimick how we do other fxaclient interactions (I haven't actually tested it locally). It seems to me that these kinds of actions should be side-effects of FxA state machine transitions, but it doesn't seem like a well isolated sort of a thing that is easy to change, so I'm OK with this for now. ::: mobile/android/services/src/main/java/org/mozilla/gecko/fxa/receivers/FxAccountDeletedService.java:78 (Diff revision 1) > Logger.warn(LOG_TAG, "Intent malformed: no account name given.

No, but since this is an interface we have to implement the method, so might as well do it right instead of throwing UnsupportedOperationException :)
