[WebViewExample] Bundled HTML does not work

[lu-ko]

I cannot render bundled HTML file in WebView. I suppose it is a bug in React Native because it does not work also in your WebViewExample and UIExplorer.

Error in Android emulator:

• E/ReactNativeJS: Requiring unknown module "./helloworld.html". If you are sure the module is there, try restarting the packager.
• Restart of packager did not help.
• React Native version: 0.19

Error in your online UIExplorer:

• Error loading page. Domain: NSURLErrorDomain. Error Code: -1100. Description: The requested URL was not found on this server.
• See screenshot.

It's fixed in React Native v.0.20, but there is still the same error in UIExplorer. Maybe it was not upgraded to latest version yet. Thank you guys!

+1 It doesn't work on the latest 0.25.1

[slootzky]

@comiclee one solution is to load the html with require , I still haven't upgraded to 0.25 but it works for 0.23

@rotemsloo, require html files can work in develope mode, but fails in release apk file

+1. I'm seeing this on latest version. Debug build is fine, but release shows blank page.

Looking at release build now. Thanks for the heads up.

As far as I can tell this got fixed. I'm going to close this issue but if people see it recur with recent builds of React Native please feel free to open a new issue.

Its still not working, I mean its not fixed.

RN 0.36 on Android. Assets need to be manually placed as suggested above.

[eggli]

Not working on RN 0.37 as well.

[xsstomy]

Not working on RN 0.39.2 as well.

[Lxxyx]

Not working on RN 0.40 as well.

[raymall]

Not working on RN 0.41 as well.

on RN 0.40, require('./file.html') is failing for me in Build release variant. as others have mentioned above.
As workaround, I was able to put the file in android assets dir, and { uri: file:///android_asset/file.html } it in from there. Unfortunately for my situation, the html file loads remote third-party libs which internally reference protocol-agnostic resources: e.g., //domain.com/file.json. So those all got turned into file://domain.com/file.json links and of course failed.
I monkey patched XMLHttpRequest to change //... to https://... which solved that problem, but none of the images those libs attempt to load, will load. all broken. And I've been unable to find a way to determine what the requests look like for those images, to see why they break/fail-to-load.

As @lacker was saying we should open a new issue, has anyone opened a new issue for this? Or should we continue in this thread? For me, it seems we should continue here only and re-open this one.

It looks like this is being tracked in this issue now: #7924
