865647 - Dungeon Fury fails to load with InvalidStateError

Status: RESOLVED WONTFIX

(Firefox for Android Graveyard :: Web Apps (PWAs), defect, P1)

Description

[James Willcox (:snorp) ([e-mail]) (he/him)]

If you try to run the installed version of Dungeon Fury (http://dungeonfury.playcanvas.com/), it will fail to load with some InvalidStateErrorS. Folks from PlayCanvas confirmed that it was doing some XHR stuff there. It seems like this could be a bug on our end? Everything works fine when running in the browser (not as a web app), and it also works in the B2G simulator.

I'm not fully convinced those errors are the actual cause of the hang. But they're certainly very concerning.

The lines about cache misses are expected and can be ignored. The 'InvalidStateError' is only printed for when running the packaged app vs the regular web page version of the game.

Probably something involving the app:// handling going awkward here.

It would be helpful to get a debugger hooked up to the app to better diagnose this. It could be this is due to cross-domain issues.

To wesj for now.

[Will Eastcott]

What is the process to attach a debugger to a packaged app?

> What is the process to attach a debugger to a packaged app?

There really is none yet. We talked about making an Intent, which could be sent to a running app, that would enable/disable the remote debugging tools.

Per bug 1235869, we're going to disable the Android web runtime, so we won't fix this bug in it.

(This is part of a bulk resolution of bugs in the Firefox for Android::Web Apps component, from which I attempted to exclude bugs that are not specific to the runtime, but it's possible that I included one accidentally.  If so, I'm sorry, and please reopen the bug!)
