Bromite: Remote DevTools HTTP/1.1 404 Not Found

Cannot reproduce, works fine here. Perhaps you have a proxy or similar interception mechanism?

Your guess is as good as mine. I have no idea why. Probably will try test against a freshly wiped Android sometime.

That URL is reachable and there is no 404. You might have some malicious certificate installed. Does it happen equally on 4G or wifi?

If I had to guess though, it'd be that the inspector resources were marked as "non-critical" in Android builds and are no longer being bundled into local builds by default.

@nikolowry Chromium moved the devtools resources into a third-party git submodule and indeed there is a DFM for it. Bromite disables it with the dfmify_dev_ui=false GN arg, which causes chrome/dev_ui_resources.pak to be included in the APK. Perhaps you could try building with that set to true (the default) to see if problem persists?

There are no other relevant changes as far as I can recollect, and both Bromite and the corresponding Chromium builds use this flag so they should both be affected (have you checked?)

As I wrote here the address devtools://devtools/remote/serve_rev/@4738de409d42eeb4071c354860aae28c8ab13ce6/inspector.html?remoteVersion=81.0.4044.106 is accessible.

Fixed in 83.0.4103.46.
